<span style="font-family: "trebuchet ms", sans-serif;"><b>Linksys Access Point : -</b>When you planning to buy the Linksys
access point for extend your existing wireless network, probably you have to
know about how configure this device. may be other network devices you know the how to configure the IP
address but there there is no DHCP server, its mean when you connect in your PC it will not generated IP because its don't have any default IP address, therefore we can show you how to configure you Linksys Access Point step by step...</span></div>

<span style="background-color: white; color: #505050; font-size: 16px; line-height: 30px;"><span style="font-family: Trebuchet MS, sans-serif;">802.11ac is the next generation for wireless networks and manufacturers are now deploying equipment with this new technology and marketing the heck out of it. Now the question is when should you look at deploying it and what do you benefit from these new wireless solutions ?</span></span></div>
<div style="text-align: justify;">

<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: Trebuchet MS, sans-serif;">If you have recently deployed an 802.11n network I wouldn’t
worry about it. You still have lots of life left in your investment and unlike
previous generations of wireless networks this one is ok to mix in with your
current 802.11n wireless network. That means you can buy an 11ac AP here and
there over time and replace or supplement your existing wireless network with
these new APs. There are lots of things to consider though when deciding how to
deploy this new technology but for right now we are going to focus on what does
AC offer versus N wireless.</span><o:p></o:p></div>

<div style="text-align: justify;">
<span style="font-family: Trebuchet MS, sans-serif;">The first big gain we get with 802.11ac wireless is faster speeds. Faster speeds mean more bandwidth for everyone involved because the faster I can get you the data you requested the faster I can get to the next guy in line who is trying to get to his Vine video of the day. With 802.11ac the first generation of APs is going to provide up to 1.3Gbps of bandwidth. This is about 3x the bandwidth we can currently get from an 802.11n AP with dual radios today. The speeds of course are all dependent on optimal variables like, client device capability, distance from the AP, RF quality, etc… So suffice it to say that 802.11ac is like replacing your family sedan with a Ferrari!</span></div>

<span style="font-family: Trebuchet MS, sans-serif;">
<b>Range</b></span></h3>
<span style="font-family: Trebuchet MS, sans-serif;">
<div>
<br /></div>
<div style="text-align: justify;">
The first point to make is the 802.11ac standard lives entirely in the 5GHz spectrum. While some more modern routers broadcast 802.11n in 5GHz as well as 2.4GHz they remain relatively rare. </div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEimwTy23I2T2sGsMyTAXmIhpfpglQTv_ksSIgGwhhre_x4GW-6oCrB9oxe2Y9ks7dMvhCH-sVkME7FQWG27qaL1gLro12qg_4U3gy0UM6duW7SluW18huHA9HFPZOHn2okg9JK0Jr6l1N5g/s1600/long-range-wifi.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEimwTy23I2T2sGsMyTAXmIhpfpglQTv_ksSIgGwhhre_x4GW-6oCrB9oxe2Y9ks7dMvhCH-sVkME7FQWG27qaL1gLro12qg_4U3gy0UM6duW7SluW18huHA9HFPZOHn2okg9JK0Jr6l1N5g/s1600/long-range-wifi.jpg" height="262" width="320" /></a></div>
<div style="text-align: justify;">

<div style="text-align: center;">
<script type="text/javascript"><!--

<div style="text-align: justify;">
Consequently, the 5GHz spectrum tends to be 'quiet', meaning much less interference from neighbourhood Wi-Fi. This more than counters the fact that, in lab conditions, 5GHz signals do not actually broadcast as far as 2.4GHz signals. 5GHz is also necessary to support the faster speeds of wireless ac. </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
The second key factor is 802.11ac makes ‘beamforming’ a core part of its spec. Rather than throw out wireless signal equally in all directions, WiFi with beamforming detects where devices are and intensifies the signal in their direction(s). </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
This technology has been around in proprietary form (it made a huge impact in the D-Link DIR-645), but now it will be inside every 802.11ac router and every 802.11ac device. </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
The combination of these two technologies is profound. This was most clearly seen with the Linksys EA6500 which hit speeds of 30.2MBps (241.6Mbit) when connecting to a device just two metres away, but still performed at 22.7MBps (181.6Mbit) when 13 metres away with two solid walls in the way. By contrast Linksys’ own EA4500 (identical except being limited to 802.11n) managed 10.6MBps (84.8Mbit) dropping to 2.31MBps (18.48Mbit) under the same conditions. </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
The real world result is 802.11ac not only enables you to enjoy the fastest 100Mbit (and beyond) fibre optic broadband speeds all over the house, but to enjoy it along with multiple streams of Full HD content, super low latency gaming and blazing fast home networking all at the same time. </div>
</span></div>
<h3 style="text-align: left;">
<span style="font-family: Trebuchet MS, sans-serif;">Capacity </span></h3>
<div style="text-align: justify;">
<span style="font-family: Trebuchet MS, sans-serif;">The next big gain 802.11ac provides us is better client capacity. With 802.11n wireless we recommended no more than 30-40 clients to an AP for optimal performance. This isn’t because of limitations in the access point hardware but rather limitations based on bandwidth. RF is a shared medium and there isn’t an unlimited amount of airtime or bandwidth. Because wireless clients are sharing the bandwidth on an AP each is only going to get a slice of the total amount of bandwidth offered by it. For instance, a dual radio 802.11n AP that provides 450Mbps to 50 clients is going to net each client about 9Mbps in total bandwidth. When you factor in overhead, spectrum interference, etc… the actual total bandwidth to the client will be much less. If my client count is less on the AP each client will have more bandwidth allocated to them. 25 clients on the same 802.11n AP will net 18Mbps per client which is much better than 9Mbps. With 802.11ac we have a lot more bandwidth to distribute and better methods of doing it so the client count can be much higher on an 802.11ac access point than on 802.11n.</span></div>

The first thing to get out of the way is - like past Wi-Fi standards - 802.11ac is backwards compatible with 802.11b, g and n. This means you can buy an 802.11ac-equipped device and it will work just fine with your existing router. Similarly you can upgrade to an 802.11ac router and it will work happily with all your existing devices. That said you will need both an 802.11ac router and an 802.11ac device to enjoy the standard’s biggest benefits. And those begin with…</div>

<b>What is FTP Server ?</b><br />
<b><br /></b>
<br />
<div class="MsoNormal" style="text-align: justify;">

<br />
<b>Why is require for business environment ?</b><br />
<br />
Setting up an FTP server becomes necessary for businesses that manage their own network and need to establish a file transfer connection to facilitate the exchange of documents between company employees. It is also needed by web hosting companies that empower their clients to upload websites to the hosting servers they are managing. Also, the installation of an FTP server application is a good solution if you're a person who needs to share a large number of files over the Internet.<br />

<b><br /></b></div>
<div style="text-align: justify;">
Most computer operating systems already come with an FTP client; however, it is not user-friendly. Start up a command prompt window, type "ftp" and then press “enter.” Chances are you will be greeted by an "ftp>" prompt. Unless you are well-versed with using command lines and enjoy typing, there are much easier ways to FTP.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
FTP Explorer is an FTP client application. It is designed to make FTP simple and hassle-free. Most people agree it is much easier to use than a command line FTP client. </div>

Supporting both SFTP and SCP protocols (upshot: secure transfers), WinSCP is fast and lightweight while still supporting advanced features like remote text editing. When you open a plain text file, WinSCP can open the file in your text editor of choice. Every time you save the file, it transparently saves and uploads the changes to the remote server. Added bonus: a portable version is available. WinSCP's synchronized browsing feature is also worth a look.</div>

FireFTP isn't the most feature-rich client of the bunch, but if all you need is a simple FTP client for the occasional upload or download, FireFTP is more than up for the job. Even better: You don't have to install a separate program for FTP, since it all runs from the warm and fuzzy comfort of the 'fox. If you're running Portable on your thumb drive, you can take FireFTP with you wherever you go.P</div>

<div class="MsoNormal" style="text-align: justify;">
Anybody who wants to test their
connection speed can easily do so from a speed test web site — but that isn’t
very geeky. Here’s how to do a test from the terminal prompt instead.<o:p></o:p><br />
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
<i>(Note: If you are using
Windows, you’ll want to either have Cygwin installed, or have a copy
of curl or wget installed. On the Mac you can use curl, but if you prefer wget,
you’ll need to install that.)</i><o:p></o:p></div>
<div class="MsoNormal" style="text-align: justify;">
<h3>
Testing Internet Connection Speed
with Curl</h3>
<o:p></o:p></div>
<div class="MsoNormal" style="text-align: justify;">
This is pretty simple. Just copy
and paste the following command:<o:p></o:p><br />
<br /></div>
<div style="text-align: center;">
<script type="text/javascript"><!--
google_ad_client = "ca-pub-8373630961471632";
/* 460*60 */
google_ad_slot = "6102938812";
google_ad_width = 468;
google_ad_height = 60;
//-->
</script>
<script src="//pagead2.googlesyndication.com/pagead/show_ads.js" type="text/javascript">
</script></div>
<div class="MsoNormal" style="text-align: justify;">
<i><b>curl -o
/dev/null http://speedtest.sea01.softlayer.com/downloads/test100.zip</b></i><o:p></o:p><br />
<i><b><br /></b></i></div>
<div class="MsoNormal" style="text-align: justify;">
The first thing to point out is
that we’re using a test file from Softlayer, but if your connection is
really fast, you might want to use a larger file from Thinkbroadband to
properly test. Secondly, that -o switch is the lower case form of the
letter O. It’s not a zero, and if you omit it, your terminal will turn into
crazyville since curl will try to output to the screen — it’s also important
because we’re outputting the file to /dev/null, which means it’ll basically be
automatically deleted.<o:p></o:p></div>
<div class="MsoNormal" style="text-align: justify;">
<h3>
Testing Internet Connection Speed
with Wget</h3>
<o:p></o:p></div>
<div class="MsoNormal" style="text-align: justify;">
If you prefer using wget, or that
is what you have installed, the switch is the same. That is a capital letter
“o” and it sends the output straight to null, so you don’t have any files to
delete.<o:p></o:p><br />
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
<i><b>wget -O /dev/null
http://speedtest.sea01.softlayer.com/downloads/test100.zip</b></i><o:p></o:p><br />
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
This file is only 100 MB, so if you
have a really fast connection, this isn’t going to work very well, and you’ll
want to find a bigger file to download from the site linked above.</div>

<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: Trebuchet MS, sans-serif;">In computer networking, DMZ is a
firewall configuration for securing local area networks (LANs).<o:p></o:p></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: Trebuchet MS, sans-serif;">In a DMZ configuration, most
computers on the LAN run behind a firewall connected to a public
network like the Internet. One or more computers also run outside the firewall,
in the DMZ. Those computers on the outside intercept traffic and broker
requests for the rest of the LAN, adding an extra layer of protection for
computers behind the firewall.<o:p></o:p></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: Trebuchet MS, sans-serif;">Traditional DMZs allow computers
behind the firewall to initiate requests outbound to the DMZ. Computers in the
DMZ in turn respond, forward or re-issue requests out to the Internet or other
public network, as proxy servers do. (Many DMZ implementations, in
fact, simply utilize a proxy server or servers as the computers within the
DMZ.) The LAN firewall, though, prevents computers in the DMZ from initiating
inbound requests.<o:p></o:p></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: Trebuchet MS, sans-serif;">DMZ is a commonly-touted feature
of home broadband routers. However, in most instances these features are not
true DMZs. Broadband routers often implement a DMZ simply through additional
firewall rules, meaning that incoming requests reach the firewall directly. In
a true DMZ, incoming requests must first pass through a DMZ computer before
reaching the firewall.</span><o:p></o:p></div>

<span style="font-family: Georgia, Times New Roman, serif;">Last couple of month we are facing the problem of frequently
dropping internet connection, and after the reset internet line from ISP we
don’t get any change of situation, I asked to the ISP help desk but they doesn’t
successfully resolve the issues.</span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;">Dropping connectivity is not good impact to business as well users, and after lots of goggling finally i got the solution of dropping connection, I try to degrade the my Linksys Router (WAG160N), and its un-believable after degrade my problem is resolve. Now Internet connection is working perfectly and no more dropping . </span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;">So if you are also getting the problem of dropping Internet connection
then try to degrade the router firmware.</span><br />

<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;">With the priority of the Asterisk box set to high, we should
be all set. It turns out that unless you cap the bandwidth, you will
still have QoS problems. Enter around 85% of your up and down bandwidth
in the Uplink and Downlink boxes. Capping the bandwidth is required to
keep the latency low. Otherwise, your bandwidth is filled up with large
packets and the priority settings are not effective for VOIP traffic. See <a href="http://www.dd-wrt.com/wiki/index.php/Quality_of_Service">http://www.dd-wrt.com/wiki/index.php/Quality_of_Service</a> for

<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;"><br /></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Like all sufficiently advanced
technologies, Wi-Fi can feel like magic. But Wi-Fi isn’t magic – its radio
waves. A variety of things can interfere with these radio waves, making your
wireless connection weaker and more unreliable.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;"><br /></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">The main keys to improving your
wireless network’s signal are positioning your router properly — taking
obstructions into account — and reducing interference from other wireless
networks and household appliances.</span></div>
<h4 style="text-align: left;">
<span style="font-family: georgia, "times new roman", serif;">Wireless Router Positioning</span></h4>
<div class="MsoNormal" style="text-align: justify;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjWT8BrgEjfvjmDCTmpWsjpkvNQzwTh9AzSYzSuepxzfLESnARqJ-N-l9Q4Vf3ye4wNBI_4kpQ4Q-_EXLvUIt7DNV965Hl7OdFvsvOsSrtdlLaSzN5HjyPIi4OeS3YH5pQmmkn-8zWs1g0u/s1600/Positioning.jpg" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="180" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjWT8BrgEjfvjmDCTmpWsjpkvNQzwTh9AzSYzSuepxzfLESnARqJ-N-l9Q4Vf3ye4wNBI_4kpQ4Q-_EXLvUIt7DNV965Hl7OdFvsvOsSrtdlLaSzN5HjyPIi4OeS3YH5pQmmkn-8zWs1g0u/s200/Positioning.jpg" width="200" /></a><span style="font-family: georgia, "times new roman", serif;">Your wireless router’s
positioning can greatly affect your coverage area and the strength of your
signal. Follow these quick tips to position your router for the best signal.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;"><br /></span></div>
<div class="MsoNormal" style="text-align: justify;">
</div>
<ul>
<li><span style="font-family: georgia, "times new roman", serif;">Place the router in the middle of
your house. If you place the router in a room off to the side of your house,
you won’t get as strong a signal on the other side of your house.</span></li>
<li><span style="font-family: georgia, "times new roman", serif;">Position the router’s antenna
vertically, so that the antenna is standing straight up. Many antennas can be
adjusted and lie horizontally, but standing straight up is generally the ideal
position.</span></li>
<li><span style="font-family: georgia, "times new roman", serif;">Elevate your router away from
floors. You’ll get better reception if the router is on a desk, not on the
floor.</span></li>
</ul>
<br />
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">You should also pay attention to
the kinds of materials the router is near. For example, placing the router on a
metal desk or up against a metal wall will cause problems. Signals can travel
through a wood desk easily, but metal will obstruct the signals.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Other types of obstructions can
also cause problems. For example, if there’s a metal filing cabinet between
your computer and the router, you may not receive a wireless signal. The same
applies to other types of dense objects.</span></div>
<h4 style="text-align: left;">
<span style="font-family: georgia, "times new roman", serif;">Interference From Other Wireless
Networks</span></h4>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Interference from other wireless
networks in the area can cause issues with your wireless signal. To determine
whether interference is occurring, you can use an app like <a href="https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer&feature=search_result" target="_blank">Wi-FiAnalyzer for Android</a>. It will show you the wireless channels nearby
networks are using and recommend the ideal network for you to use — one that
isn’t being used by as many networks. This app will also allow you to walk
around the area and see where you get the best signal and where the signal is
weakest – you can do this with any other device, too.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">If multiple wireless networks are
competing for the same channel, this can cause problems. To fix this, you can change
the wireless channel in your router’s web interface. You can do this even
if you don’t have access to a wireless-analyzing app – change the signal to a
different channel and then see if your wireless connection improves.</span></div>
<h4 style="text-align: left;">
<span style="font-family: georgia, "times new roman", serif;">Interference From Household
Appliances</span></h4>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">A variety of household appliances
can cause wireless interference, including cordless phones, baby monitors, and
microwave ovens. Depending on the positioning of your wireless router, your
networked device, and the appliance, you may even have the wireless network cut
out when the microwave or cordless phone is in use.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Problems with cordless phones can
be solved by replacing your phones with phones that operate on a different
frequency, such as 900 MHz or 1.9 GHz. Cordless phones using the 2.4 Ghz
frequency will interfere with wireless networks.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Problems with microwaves can
often by solved by positioning the your devices such that the microwave isn’t
between your router and the device. it’s also possible that a new microwave
will help, if the new microwave has better shielding.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Other devices can also cause
problems. For example, older Bluetooth devices can interfere with nearby Wi-Fi
signals, although newer Bluetooth devices don’t.</span></div>
<h4 style="text-align: left;">
<span style="font-family: georgia, "times new roman", serif;">Repeaters, Antennas, and Reflectors</span></h4>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiEYGoK3KJGT2nzHgN8BgyxAhFnUtDIHnQI4SGT8s4oXuBNIhYvNNDu1BuZ1WrpAeY31p1Ho1GUF2xO7Uh77jCsSoTEE4-JFdtZNvQFmZcc5IZ6nwXLSYMiVt0hGiNb39QftL9JY-Ex_x32/s1600/wifi2.jpg" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="98" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiEYGoK3KJGT2nzHgN8BgyxAhFnUtDIHnQI4SGT8s4oXuBNIhYvNNDu1BuZ1WrpAeY31p1Ho1GUF2xO7Uh77jCsSoTEE4-JFdtZNvQFmZcc5IZ6nwXLSYMiVt0hGiNb39QftL9JY-Ex_x32/s200/wifi2.jpg" width="200" /></a></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">If you need to cover a large area
with a wireless signal and your router just isn’t cutting it, you can buy a
wireless repeater or range extender. These devices repeat the wireless signal,
extending its area. You don’t even need special devices for this – if you have
some old routers around, you can use
multiple routers to extend your Wi-Fi network.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Depending on your router, you may
be able to attach an improved
antenna that gives your signal additional range. You can also try building
a Wi-Fi reflector that reflects the signal in a specific direction.</span></div>

<span style="font-family: georgia, "times new roman", serif;">Many businesses depend upon the
ability to access their servers and documents from multiple locations. To
enable that, many take advantage of the Virtual Private Network (VPN). When
proposing this to end users, it is very often met with fear and uncertainty. It
is change and people don't like change. To make that easier for end users,
selecting the right VPN client is key. Some VPN servers (such as Sonicwall and
Fortinet) require you use their own proprietary clients. But other VPNs allow
the use of third party clients.<span style="background-color: white; color: #37414b; font-size: 8pt; line-height: 115%;"> </span>As
for the third-party clients, there are quite a lot of them out there. Some are
free, some are cheap, some are worth your time, and some are not. I have
gathered together five of the clients I believe to be worth looking into. Each
client may or may not meet your VPN needs – that will depend upon the server
you are running. But each client offers plenty of features and each offers
different levels of user-friendliness.</span></div>

<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Cables are commonly used to carry
communication signals within LAN. There are three common types of cable media
that can be used to connect devices to a network and they are coaxial cable,
twisted-pair cable, and fiber-optic cable.</span></div>
<h4 style="text-align: left;">
<ul style="text-align: left;">
<li><span style="font-family: georgia, "times new roman", serif;"><u>Coaxial cable</u></span></li>
</ul>
</h4>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Coaxial cable looks similar to
the cable used to carry TV signal. A solid-core copper wire runs down the
middle of the cable. Around that solid-core copper wire is a layer of
insulation, and covering that insulation is braided wire and metal foil, which
shields against electromagnetic interference. A final layer of insulation
covers the braided wire.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">There are two types of coaxial
cabling: thinnet and thicknet. Thinnet is a flexible coaxial cable about ¼
inches thick. Thinnet is used for short-distance. Thinnet connects directly to
a workstation’s network adapter card using a British Naval Connector (BNC). The
maximum length of thinnet is 185 meters. Thicknet coaxial is thicker cable than
thinnet. Thicknet cable is about ½ inch thick and can support data transfer over
longer distances than thinnet. Thicknet has a maximum cable length of 500
meters and usually is used as a backbone to connect several smaller
thinnet-based networks.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">The bandwidth for coaxial cable
is 10 mbps (mega bits per second).</span></div>
<h4 style="text-align: left;">
<ul style="text-align: left;">
<li><span style="font-family: georgia, "times new roman", serif;"><u>Twisted Pair Cable</u></span></li>
</ul>
</h4>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Twisted-pair cable is the most
common type of cabling you can see in todays LAN networks. A pair of wires
forms a circuit that can transmit data. The pairs are twisted to provide
protection against crosstalk, the noise generated by adjacent pairs. When a wire
is carrying a current, the current creates a magnetic field around the wire.
This field can interfere with signals on nearby wires. To eliminate this, pairs
of wires carry signals in opposite directions, so that the two magnetic fields
also occur in opposite directions and cancel each other out. This process is
known as cancellation. Two Types of Twisted Pairs are Shielded Twisted Pair
(STP) and Unshielded Twisted Pair (UTP).</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Unshielded twisted-pair (UTP)
cable is the most common networking media. Unshielded twisted-pair (UTP)
consists of four pairs of thin, copper wires covered in color-coded plastic
insulation that are twisted together. The wire pairs are then covered with a
plastic outer jacket. The connector used on a UTP cable is called a Registered Jack
45 (RJ-45) connector. UTP cables are of small diameter and it doesn’t need
grounding. Since there is no shielding for UTP cabling, it relies only on
the cancellation to avoid noise. </span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">UTP cabling has different
categories. Each category of UTP cabling was designed for a specific type of
communication or transfer rate. The most popular categories in use today is 5,
5e and 6, which can reach transfer rates of over 1000 Mbps (1 Gbps).</span></div>
<h4 style="text-align: left;">
<ul style="text-align: left;">
<li><span style="font-family: georgia, "times new roman", serif;"><u>Optical Fiber Cabling</u></span></li>
</ul>
</h4>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Optical Fiber cables use optical
fibers that carry digital data signals in the form of modulated pulses of
light. An optical fiber consists of an extremely thin cylinder of glass, called
the core, surrounded by a concentric layer of glass, known as the cladding.
There are two fibers per cable—one to transmit and one to receive. The core
also can be an optical-quality clear plastic, and the cladding can be made up
of gel that reflects signals back into the fiber to reduce signal loss. </span><span style="font-family: georgia, "times new roman", serif;">There are two types of fiber
optic cable: Single Mode Fibre (SMF) and Multi Mode Fibre (MMF). </span><span style="font-family: georgia, "times new roman", serif;">1. Single Mode Fibre (SMF) uses a
single ray of light to carry transmission over long distances. </span><span style="font-family: georgia, "times new roman", serif;">2. Multi Mode Fibre (MMF) uses
multiple rays of light simultaneously with each ray of light running at a
different reflection angle to carry the transmission over short distances.</span></div>

<span style="font-family: georgia, "times new roman", serif;">Almost
anyone who has connected to the Internet through a broadband connection (like
cable or DSL) has used an Ethernet cable to do it. You have connected your PC’s
network interface card (NIC) to your cable modem, DSL modem, or home router
with an Ethernet cable. Because of the commonality of this, if I say “use
an Ethernet cable” you have a picture of a cable in your mind. However,
you should know that there is more than one type of Ethernet cable.</span></div>

<span style="font-family: georgia, "times new roman", serif;">Cat 3 cable
is an unshielded twisted pair cable (UTP). UTP is used in scenarios where
electromagnetic interference is of little concern; the wire architecture
shields the individual wires from crosstalk. In using UTP, network architecture
spending can remain low while offering sufficient reliability for short- to
mid-range signal transmission.</span></div>

<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">CAT5 (also, CAT 5) is
an Ethernet network
cable standard defined by the Electronic Industries Association and
Telecommunications Industry Association (commonly known as EIA/TIA). CAT5 is
the fifth generation of twisted pair Ethernet technology and the most popular
of all twisted pair cables in use today.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">CAT5 cable contains four pairs of
copper wire. It supports Fast Ethernet speeds (up to 100 Mbps). As
with all other types of twisted pair EIA/TIA cabling, CAT5 cable runs are
limited to a maximum recommended run length of 100m (328 feet).</span></div>
<div class="MsoNormal" style="text-align: justify;">
</div>
<ul>
<li><b><span style="font-family: georgia, "times new roman", serif;"><u>Category 5 (CAT 5e)</u></span></b></li>
</ul>
<br />
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">This category is an enhanced
version of Cat 5 that prevents interference between one unshielded twisted pair
to another twisted pair running in parallel within the same cable (Far End
Crosstalk - FEXT).<br />
As network and telecommunication applications become more complex, increased
data transport is required to accommodate fast data transfer speeds. CAT 5 is
typically used in Local Area Networks (LAN) and premise cabling. Category 5e
cabling is an enhanced version of CAT 5 cabling. The main difference between
CAT 5 and CAT 5e cabling is the specifications. The amended specifications
provide full-duplex Fast Ethernet cabling. CAT 5e uses better insulation to
improve attenuation and crosstalk performance. An additional plastic rib has
been placed in the center of CAT 5e cabling to reduce crosstalk. A twist
internal to the jack prevents untwisting and crosstalk to other wire pairs.
Some of the benefits of CAT 5e interconnect include:</span></div>
<div class="MsoNormal" style="text-align: justify;">
</div>
<ul>
<li><span style="font-family: georgia, "times new roman", serif;">Speed: can carry speeds up to
100 Mb/second, will expand to 10 Gigabits/second in the future.</span></li>
<li><span style="font-family: georgia, "times new roman", serif;">Bandwidth: greater bandwidth
than CAT 3, 4</span></li>
<li><span style="font-family: georgia, "times new roman", serif;">Distance: Cables support
distances up to 50 ft</span></li>
<li><span style="font-family: georgia, "times new roman", serif;">Price: CAT 5e cabling is much
cheaper than fiber and coax cable</span></li>
<li><span style="font-family: georgia, "times new roman", serif;">Reliable: the most implemented
and proven standards</span></li>
<li><span style="font-family: georgia, "times new roman", serif;">Size, weight and flexibility:
smaller connectors allow for high port density, the cable is lightweight, and
the jacket is flexible hp CAT 5e networking and telecommunications connectivity

<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Short for Category 6, Cat-6 network cabling
is used as the cabling infrastructure for 10BASE-T (Ethernet), 100BASE-TX (Fast
Ethernet),1000BASE-T (Gigabit Ethernet, or GbE) and 10GBASE-T (10-Gigabit
Ethernet, or 10 GbE) networks. The Cat 6 standard provides performance of up to
250MHz (500 MHz for the newer Cat 6a standard) and can be used up to a
maximum length of 100 meters (55 meters for 10GBASE-T networks).</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">The Cat 6 standard was first
released in 2002 as part of the Telecommunications Industry Association’s
TIA/EIA-568-B.2-1 document specification. Cat 6 is backward compatible
with the Cat 3, Cat 5 and Cat 5e cable standards, and as with Cat 5 and
Cat 5e cabling, Cat 6 cables consist of four unshielded twisted pairs
(UTP) of copper wire terminated by RJ45connectors. </span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">In addition to its support for
higher performance than the Cat 5 specification, the Cat 6 standard also
includes more stringent specifications for crosstalk and system noise. While
Cat 6 is expected to supersede both Cat 5 and Cat 5e cabling in the future, all
three types of cables continue to be popular for use in network installations.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: georgia, "times new roman", serif;">Category 6 cables are by
definition a twisted pair, 100 Ohm cable which has transmission parameters
specified up to 250 MHz, Category 6 cable is also a recognized cable in

Category 7 cable (Cat 7), (ISO/IEC 11801:2002 category 7/class F), is a cable
standard for Ethernet and other interconnect technologies that can be made to
be backwards compatible with traditional Cat 5 and Cat 6 Ethernet cable. Cat 7
features even more strict specifications for crosstalk and system noise than
Cat 6. To achieve this, shielding has been added for individual wire pairs and
the cable as a whole.<br />
<br />
The Cat 7 cable standard has been created to allow 10 Gigabit Ethernet over 100
m of copper cabling (also, 10-Gbit/s Ethernet now is typically run on Cat 6a).
The cable contains four twisted copper wire pairs, just like the earlier
standards. Cat 7 can be terminated either with 8P8C compatible GG45 electrical
connectors which incorporate the 8P8C standard or with TERA connectors. When
combined with GG45 or TERA connectors, Cat 7 cable is rated for transmission
frequencies of up to 600 MHz.</span></div>
<div class="MsoNormal">
<span style="font-family: georgia, "times new roman", serif;">Category 7a (or Augmented
Category 7) operates at frequencies up to 1000 MHz, suitable for multiple applications in
a single cable including 40 Gigabit Ethernet, 100 Gigabit Ethernet,
and CATV (862 MHz). Simulation results have shown that 40 Gigabit Ethernet is
possible at 50 meters and 100 Gigabit Ethernet is possible at 15 meters. Mohsen
Kavehrad and researchers at Pennsylvania State University believe that either
32 nm or 22 nm circuits will allow for 100 Gigabit Ethernet at 100 meters.<br />
This cable type is a standard for Ethernet and other interconnect
technologies, that are backward compatible with traditional Cat 5 and Cat 6
Ethernet cables. As it has more strict specifications for crosstalk and system
noise than Cat 6 and Cat 5e, its cables and the wires, within are completely
shielded. the cable contains four twisted copper wire pairs and supports up to
600Mhz.</span><br />

<span style="font-family: "trebuchet ms", sans-serif;">Each device connected to a
network is assigned a unique IP address to identify it to the network. When one
IP address is accidentally assigned to more than one device, an IP address
conflict occurs. If your computer is using an IP address that is conflicting
with another device, you will get a pop-up error telling you that the system
has detected a conflict. To find out where the conflicting device is, check the
system log for your computer and look up the conflicting device's MAC address
by using the IPconfig command.</span></div>

<span style="font-family: "trebuchet ms", sans-serif;">At
some point, every administrator will need to diagram a network. For some, it's
their primary duty, and they tend to rely on powerful, But for those who need to use a diagramming tool only
occasionally, a cheaper solution is best. Luckily, there are several free apps
that handle the task well.<o:p></o:p></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">Here
are five tools that can help you diagram your network without breaking your

developed primarily as a CAD tool, but it also serves as a handy network
diagramming tool. It's a 2D vector editor for Windows. Although it doesn't have
all the bells and whistles of some costlier tools, it can handle the task of
diagramming your network with ease.<o:p></o:p></span></div>

open source, GTK+ diagramming tool that has a shallow learning curve and can
help you create basic network diagrams. Like CADE, Dia was inspired by Visio —
but with a much more casual approach and feel. Dia loads and saves XML
formatted documents that are gziped by default to save space. Dia is also

the old-school feel of the application. DD features include customizable

<div class="MsoNormal" style="text-align: justify;">
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">An IP address (or Internet
Protocol address) identifies each networked computer and device on a network.
When computers communicate with each other on the Internet or a local network,
they send information to each other’s IP addresses.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">Your computer likely has public
and private IP addresses. You’ll need the IP address if you’re hosting server
software – the client computers will need your computer’s IP address to connect
to it.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<h3 style="text-align: left;">
<span style="font-family: "trebuchet ms", sans-serif;">Public vs. Private IP Addresses</span></h3>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">IP addresses can be either public
or private. “Public” means an IP address can be reached from the Internet,
while “private” means it can’t. For example, in a typical home network, a
router has a public IP address on the Internet. The computers, smartphones,
game consoles, and other devices behind the router all have unique private IP
addresses on the home network. The router acts as an intermediary, forwarding
traffic to the local IP addresses that request it. From an outside perspective,
all devices on the home network are communicating with the Internet from a
single public IP address.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">Assuming you’re behind a router
performing network address translation, you have two IP addresses that
matter. Your computer’s IP address is likely a private IP address,
probably starting with 192.168 — is a range of IP addresses specially allocated
to private networks. You also likely have a public IP address, which is used
when communicating with other computers over the Internet.</span></div>

<div class="MsoNormal" style="text-align: justify;">
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">For example, if you’re hosting a
server on your computer, people on the Internet will need the public IP address
from your router to connect to your server. People behind your router — on the
same local network as your computer — will need the local IP address from your
computer to connect.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">If your computer is connected
directly to the Internet with no router sitting in between, your computer’s IP
address is a public IP address.</span></div>

<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">The easiest way to find your
public IP address is by asking a website, since that website sees your public
IP address and can tell it to you – for example, you can search for what
is my ip or what is my ip address on Google. Google will display
your public IP address.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">You can also access your router’s
administration page to find this information. This page displays your public IP
address and other information about your Internet connection. Different routers
have different administration page layouts and different default local IP
addresses – consult your router’s manual if you need more information.</span></div>

addresses aren’t necessarily fixed. Your Internet service provider may

assign your devices new IP addresses.</span><span style="text-align: left;"> </span><span style="text-align: left;"> </span></div>

<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">So how to speed up network ?
Nothing is as annoying as slow network connection. Even if you have good
hardware, you will not enjoy the real speed of your computer if your Internet
connection is slow. Sometimes the only way to make things faster is to upgrade
your broadband plan. However, there are some tips how to speed up network that
really make a difference without costing anything. Here they are.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<h3 style="text-align: left;">
<span style="font-family: "trebuchet ms", sans-serif;">Remove My Network Places
shortcuts</span></h3>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">If you are wondering how to speed
up network and make sharing files faster, you should remove all shortcuts from
My Network Places. These shortcuts are created automatically and most of the
time they are not needed. Not to mention that they often become invalid. And
when they become invalid, Windows still searches for them even when they are
never shared anymore. This slows things down. To remove these shortcuts,
highlight them and press Delete on your keyboard.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="background-color: white; font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<h3 style="text-align: left;">
<span style="background-color: white; font-family: "trebuchet ms", sans-serif;">Reset your network</span></h3>
<div class="MsoNormal" style="text-align: justify;">
<span style="background-color: white; font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">If you are thinking how to speed
up network when your Internet becomes very slow all of a sudden, you should
reset your network by restarting your router. That’s easy enough - simply
disconnect from the Internet and power down your PC. Then restart your router
by switching it off and on again. Wait for the router to fully boot and start
your computer. The speed should be back to normal.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<h3>
<span style="background-color: white; font-family: "trebuchet ms", sans-serif;">Check your router and home phone
for possible conflicts</span></h3>
<br />
<div class="MsoNormal" style="text-align: justify;">
<span style="background-color: white; font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">Another suggestion how to speed
up network. Sometimes your Internet connection can become slow because of home
phone and router conflicts. This happens when your router and your cordless
phone use the same frequency. If that’s the case, it can cause your Internet
connection to slow down every time your phone is used. So, check your phone’s technical
specs and see if there are any conflicts. If the phone uses the 900Mhz
frequency, then it shouldn’t be affecting your router. But if your phone is
using 2.4Ghz or 5.8Ghz, then it may be the cause of slow Internet connection.
To fix the problem, try moving the phone to a different room or buy a different
phone for your house.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<h3>
<span style="background-color: white; font-family: "trebuchet ms", sans-serif;">Upgrade the firmware for your
router</span></h3>
<br />
<div class="MsoNormal" style="text-align: justify;">
<span style="background-color: white; font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">Another answer to the how to
speed up network question is upgrading the firmware for your router. Quite
often your network can become slow if your router’s firmware is out of date.
That’s why you should check your router manufacturer’s site every now and again
for firmware updates and apply them as soon as they are issued. Just make sure
that you are applying the correct update for your model.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<h3>
<span style="background-color: white; font-family: "trebuchet ms", sans-serif;">How to speed up network even
more? Perform PC maintenance!</span></h3>
<br />
<div class="MsoNormal" style="text-align: justify;">
<span style="background-color: white; font-family: "trebuchet ms", sans-serif;"><br /></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">Even if you are on a fast
broadband plan, browsing the Web won’t be fast if your computer is slow. So
another way how to speed up network has little to do with the network itself –
you simply need to perform some PC maintenance. Believe it or not, deleting
temporary files, defragmenting your hard disk and running PC speedup software
can speed up your Internet connection a great deal.</span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "trebuchet ms", sans-serif;">These simple how to speed up
network tips will make using your network and browsing the Web faster and a lot
more enjoyable.</span></div>

<div style="font-family: verdana, sans-serif;">
<span style="font-size: small;"><br />
</span></div>
<span style="font-family: "trebuchet ms", sans-serif; font-size: small;">WPA2 security is one of the highest-security options available for wireless networks. It is designed with longer encryption keys to make it more difficult for hackers to break into the network. If you are unable to connect to a WPA2-enabled wireless Internet network, the problem may lie with your computer hardware or the Internet service itself.</span></div>
<div style="text-align: center;">

<span style="font-family: "trebuchet ms", sans-serif; font-size: small;"><b>Wireless Settings </b></span></h2>
<h2 class="header Heading3" style="color: black; text-decoration: none;">
<span style="font-family: verdana, sans-serif; font-size: small;"><span style="font-weight: normal;">If your computer is not allowing you to connect to a network with WPA2 security, your wireless settings may be the problem. Because most computers hide the passwords for a wireless login, double-check the password, paying attention to case and characters. Ensure that WPA2 security is selected from the drop-down box. If you choose the wrong security type, your computer will not be able to connect to the router</span>.</span></h2>
<h2 class="header Heading3" style="color: black; text-decoration: none;">
<span style="font-family: "trebuchet ms", sans-serif; font-size: small;">Wireless Card</span></h2>
<div style="color: black; text-decoration: none;">
<span style="font-family: "trebuchet ms", sans-serif; font-size: small;">Computers that came with built-in wireless networking capabilities usually support most types of security. If you modified your computer by adding a wireless adapter and you cannot connect to a WPA2 network, the card may be the problem. Some older wireless cards are not able to support WPA2 security. In this case, you will need to replace the wireless adapter with one that is designed to support newer security protocol.</span></div>
<div style="color: black; text-decoration: none;">
<span style="font-family: "trebuchet ms", sans-serif; font-size: small;"><br />
</span></div>
<h2 class="header Heading3" style="color: black; text-decoration: none;">
<span style="font-family: "trebuchet ms", sans-serif; font-size: small;">Drivers and Firmware</span></h2>
<div style="color: black; text-decoration: none;">
<span style="font-family: "trebuchet ms", sans-serif; font-size: small;">If your wireless adapter drivers or router firmware is out of date, it can hinder the computer's ability to connect to a WPA2 network. The most recent drivers will be available for download on the manufacturers' websites. Updating your computer's software can also enable it to communicate with the wireless adapter. On a PC, choose Windows Update from the Start menu. On a Mac, choose Software Update from the Apple menu.</span></div>
<div style="color: black; text-decoration: none;">
<span style="font-family: "trebuchet ms", sans-serif; font-size: small;"><br />
</span></div>
<h2 class="header Heading3" style="color: black; text-decoration: none;">
<span style="font-family: "trebuchet ms", sans-serif; font-size: small;">Wireless Utility</span></h2>
<div style="color: black; text-decoration: none;">
<span style="font-family: "trebuchet ms", sans-serif; font-size: small;">For computers running Windows, the wireless utility controls how you connect to the Internet. If your wireless utility is outdated or corrupt, it can cause trouble connecting to a network. In Windows XP, for example, problems connecting to WPA2 networks are known issues. The wireless capabilities come with service pack updates; to find the most recent updates, visit the Microsoft Download Center.</span></div>

<span style="font-size: small;">I know, that wasn't very helpful. But it's actually accurate. Your computer was able to connect the network in one way, but was unable to complete the next step.</span></div><span style="font-size: small;"><a href="http://www.blogger.com/post-edit.g?blogID=4684031584708958338&postID=412245809876991066"></a></span><br />
<div style="color: #0c4599;"><span style="font-size: small;">•</span></div><div class="entrymore"><span style="font-size: small;">"Limited connectivity" happens when:</span><br />
<table class="floatbug" style="margin-left: 0px; margin-right: 0px; text-align: left;" summary="float bug work around"><tbody>
<tr><td><ul class="spacedlist"><li><span style="font-size: small;">Your computer detects that a network is present and operating. That means that it detects that the network cable is plugged in, or that it was able to connect to a wireless access point.</span></li>
<li><span style="font-size: small;">Your computer's request for an IP address went unanswered.</span></li>
</ul></td></tr>
</tbody></table><span style="font-size: small;">It's that last one that needs a little explanation.</span><br />
<span style="font-size: small;">An IP address is how your computer is located on its network. The vast majority of machines are configured to connect to the network using <a href="http://ask-leo.com/what_is_dhcp.html"><b><span style="color: #0c4599;">DHCP</span></b></a> to get what's called a "dynamic" IP address. That means that rather than permanently assigning a specific IP to that machine, the machine "asks" for an IP address when it connects to the network.</span><br />
<span style="font-size: small;">Dynamic IP addresses are simpler to configure, and allow for IP addresses to be re-used when the machines that they were temporarily assigned to are taken offline.</span><br />
<div class="pullQuote"><span style="font-size: small;">"If you check your IP on your machine and it starts with '169.' that's a made-up IP address."</span></div><span style="font-size: small;">A DHCP request for a dynamic IP address is very simple: your computer broadcasts to all the devices listening on its network "Would the DHCP server listening please assign me an IP address!". On each such network there should be one device that hears that request and responds with something like "Here ya go: you will be 192.168.1.4 - and by the way, when you want to talk to others on your network, here's some more information, and when you want to send something to the internet, send it here."</span><br />
<span style="font-size: small;">In other words your computer gets both its IP address as well as instructions on how to talk to the rest of the world.</span><br />
<span style="font-size: small;">At that point your computer is ready to communicate with the world.</span><br />
<span style="font-size: small;">So, what happens if no one responds?</span><br />
<span style="font-size: small;">Your computer will repeat that request ("Would the DHCP server listening please assign me an IP address!") a few times, and then it'll give up.</span><br />
<span style="font-size: small;">And declare that you have limited connectivity.</span><br />
<span style="font-size: small;">Connectivity is "limited" because your computer will likely <i>make up</i> an IP address. If you check your IP on your machine and it starts with "169." that's a made-up IP address. Only your computer knows about it, which means that no other computer knows how to contact yours. In addition, your computer doesn't know how to find or send packets to anyone else.</span><br />
<span style="font-size: small;">Limited connectivity is <i>extremely</i> limited. In practice, it means <i>no</i> connectivity.</span><br />
<span style="font-size: small;">There are scenarios where, if you know what you're doing and you're willing to jump through some hoops, you can actually force communication while you're in this state by doing things like manually configuring TCP/IP settings on your network card. But it's not meant to be a long term solution at all.</span><br />
<span style="font-size: small;">So, what do you do?</span><br />
<span style="font-size: small;">DHCP is typically handled by your router, or in some cases your broadband modem. If you have a single PC connected to the internet, it may also be handled by your ISP.</span><br />
<span style="font-size: small;">Believe it or not, 90% of the time what you did is exactly right: reboot your router. Sometimes routers just "get into a state" and need to be rebooted. It's silly, and in an ideal world shouldn't be needed, but it is what it is. I probably reboot my router once a month, on average.</span><br />
<span style="font-size: small;">Wireless access points, those which are not routers but simply provide the wireless connectivity to a wired network, can sometimes also hiccup and fail in such a way as to cause this problem. I believe it happens when the wireless side of the device keeps working while the wired connection is, for some reason, inoperative. Again, a reboot of the device typically clears this up.</span><br />
<span style="font-size: small;">In either case, it's easiest to then reboot your computer(s) to force them to request new IP address assignments from the now functioning router.</span><br />
<span style="font-size: small;">If the reboot resolves the problem, but then it reoccurs quickly, I would check with the manufacturer of that device to see if there is new firmware available for it. Even though we think of routers and access points as hardware, they are in fact small computers running programs, and the programs sometimes have bugs. Sometimes those bugs don't manifest until something outside of the device changes. (I've heard anecdotal evidence that the new TCP/IP code in Windows Vista has exposed issues with some routers, for example.)</span><br />
<span style="font-size: small;">If your firmware is up to date, and the problem repeats frequently, I would investigate trying a new router or access point to see if that clears things up.</span></div></div></div>Prashant Sharmahttp://www.blogger.com/profile/04338119069519709335noreply@blogger.com0tag:blogger.com,1999:blog-2447270396302975586.post-7804265723154930652011-12-20T09:08:00.001-08:002020-05-31T23:52:35.860-07:00Give Priortize in you Network Traffice with DD-WRT<div dir="ltr" style="text-align: left;" trbidi="on"><div class="thecontent" style="font-family: verdana, sans-serif;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOgkBM3cQLJaQdsGuc1Ge4CZtzx1pqGLFhhkG9rNxhghUEN2eB582xd4mZtgQjRnLcqr2VI2FBdtKndXPny_r30lTfRMy_BAGg9P-889Ncx3Pau3gNYWkwd5FmLLpn2mZw_h6hQSfpxyVU/" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="375" data-original-width="666" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOgkBM3cQLJaQdsGuc1Ge4CZtzx1pqGLFhhkG9rNxhghUEN2eB582xd4mZtgQjRnLcqr2VI2FBdtKndXPny_r30lTfRMy_BAGg9P-889Ncx3Pau3gNYWkwd5FmLLpn2mZw_h6hQSfpxyVU/s320/Linksys_WRT54G-removebg-preview.png" width="320" /></a></div><span style="font-size: small;"><br /></span></div><div class="thecontent" style="font-family: verdana, sans-serif;"><span style="font-size: small;"><br /></span></div><div class="thecontent" style="font-family: verdana, sans-serif;"><span style="font-size: small;">Having a media server is really awesome, unless the other people on your network don’t know how to share the bandwidth. Using some simple QoS rules, you can give your computer a priority and stop your streams from dropping out.</span></div><div class="thecontent" style="font-family: verdana, sans-serif;"><span style="font-size: small;"><br /></span></div><div class="thecontent" style="font-family: verdana, sans-serif;"><span style="font-size: small;"><img alt="banner-01" border="0" height="300" src="http://www.howtogeek.com/wp-content/uploads/2011/08/banner-016.png" style="background-image: none; border: 0px none; display: inline; padding-left: 0px; padding-right: 0px; padding-top: 0px;" title="banner-01" width="650" /></span><br /><br />
<span style="font-size: small;">If you have a media server or a HTPC that streams, you’ll obviously want to make sure you can watch your content without having it stutter or drop out. The problem is, with a ton of devices on your network, the bandwidth on your HTPC needs a priority. Alternatively, maybe you have a kid who streams a little too much and is sucking up more than his or her fair share of bandwidth. You can throttle the connection to one computer without messing with the rest.</span><br />
<span style="font-size: small;">Because this tip can be used to unbalance your bandwidth as well as balance it, we urge you to exercise caution and restraint. With the great power of QoS and DD-WRT comes great responsibility.</span><br />
<h3><span style="font-size: small;">Prioritizing via MAC Address</span></h3><span style="font-size: small;">Using a computer’s MAC address is a great way to prioritize its traffic because it will work even if its IP changes. However, this really only affects prioritization if the connection is initiated from this hardware address. That means if traffic was initiated elsewhere, our settings won’t make a difference even if the destination is this particular computer. As such, this works well when trying to add importance to traffic that a computer starts, like streams, and is less effective for things like throttling torrents.</span><br />
<span style="font-size: small;">Open up your browser and head over to your DD-WRT-enabled router’s login page. Click on NAT/QoS and then QoS. This will bring you to the Quality of Service page.</span><br />
<span style="font-size: small;"><img alt="" border="" class="lazyLoad" height="327" src="http://www.howtogeek.com/wp-content/uploads/2011/08/sshot-12.png" style="background-image: none; border: 0px none; display: inline; padding-left: 0px; padding-right: 0px; padding-top: 0px;" title="sshot-1" width="623" /></span><noscript>&amp;lt;p&amp;gt;&amp;lt;img src="http://www.howtogeek.com/wp-content/uploads/2011/08/sshot-12.png" alt="" /&amp;gt;&amp;lt;/p&amp;gt;</noscript><br />
<span style="font-size: small;">Here, you want to make sure that Quality of Service is enabled, it’s set to WAN, and you’re using HTB as the packet scheduler.</span><br />
<span style="font-size: small;">You also want to set the Uplink to somewhere between 80% and 95% of the max upload bandwidth you have. The Downlink should between 80% and 100%. In theory, you want to make sure that if there’s a bottleneck in speed going into or out of your network, it’s at the router so that it can be managed.</span><br />
<span style="font-size: small;">Next, head down to the MAC Priority section.</span><br />
<span style="font-size: small;"><img alt="" border="" class="lazyLoad" height="132" src="http://www.howtogeek.com/wp-content/uploads/2011/08/sshot-23.png" style="background-image: none; border: 0px none; display: inline; padding-left: 0px; padding-right: 0px; padding-top: 0px;" title="sshot-2" width="619" /></span><noscript>&amp;lt;p&amp;gt;&amp;lt;img src="http://www.howtogeek.com/wp-content/uploads/2011/08/sshot-23.png" alt="" /&amp;gt;&amp;lt;/p&amp;gt;</noscript><br />
<span style="font-size: small;">Enter your computer’s MAC address. If you’re not sure how to look it up, check out <a href="http://www.howtogeek.com/69612/how-to-set-up-static-dhcp-on-your-dd-wrt-router/">our article on Static DHCP</a> and scroll down to see how to find your MAC address.</span><br />
<span style="font-size: small;"><img alt="" border="" class="lazyLoad" height="195" src="http://www.howtogeek.com/wp-content/uploads/2011/08/sshot-32.png" style="background-image: none; border: 0px none; display: inline; padding-left: 0px; padding-right: 0px; padding-top: 0px;" title="sshot-3" width="619" /></span><noscript>&amp;lt;p&amp;gt;&amp;lt;img src="http://www.howtogeek.com/wp-content/uploads/2011/08/sshot-32.png" alt="" /&amp;gt;&amp;lt;/p&amp;gt;</noscript><br />
<span style="font-size: small;">Then, you can just set the priority. You can set it to Premium or Express, both of which will vastly improve the speeds your computer will get.</span><br />
<h3><span style="font-size: small;">Prioritizing via IP Address</span></h3><span style="font-size: small;">When you change priorities via IP address, DD-WRT will manage all traffic, not just traffic that is initiated by that particular computer. This means that receiving IMs, torrenting, and other traffic that the computer is receiving that may start from an outside source is affected. As such, you can use this method to deprioritize a computer on your network much more efficiently, though the consequences can be made more severe by utilizing specific choices. This method works very well with a <a href="http://www.howtogeek.com/69612/how-to-set-up-static-dhcp-on-your-dd-wrt-router/">Static DHCP setup</a>, so that IP addresses are tied to individual computers and they don’t change.</span><br />
<span style="font-size: small;">Follow the above instructions, but instead of going to the MAC priority section, go down to the Netmask Priority section.</span><br />
<span style="font-size: small;"><img alt="" border="" class="lazyLoad" height="137" src="http://www.howtogeek.com/wp-content/uploads/2011/08/sshot-41.png" style="background-image: none; border: 0px none; display: inline; padding-left: 0px; padding-right: 0px; padding-top: 0px;" title="sshot-4" width="622" /></span><noscript>&amp;lt;p&amp;gt;&amp;lt;img src="http://www.howtogeek.com/wp-content/uploads/2011/08/sshot-41.png" alt="" /&amp;gt;&amp;lt;/p&amp;gt;</noscript><br />
<span style="font-size: small;">Add the IP address of the target computer, followed by the mask. The mask will tell DD-WRT what length of the IP address to apply the rule to. For example, a mask of 24 will change the priority for 192.168.1.x addresses, and a mask of 32 will change the priority of a single IP address. You will likely want to use 32.</span><br />
<span style="font-size: small;"><img alt="" border="" class="lazyLoad" height="193" src="http://www.howtogeek.com/wp-content/uploads/2011/08/sshot-51.png" style="background-image: none; border: 0px none; display: inline; padding-left: 0px; padding-right: 0px; padding-top: 0px;" title="sshot-5" width="621" /></span><noscript>&amp;lt;p&amp;gt;&amp;lt;img src="http://www.howtogeek.com/wp-content/uploads/2011/08/sshot-51.png" alt="" /&amp;gt;&amp;lt;/p&amp;gt;</noscript><br />
<span style="font-size: small;">Next, you can change the priority. If you want to increase it, choose Premium, as that will work best. If you wish to lower it, choose Standard and use this in conjunction with a prioritized computer elsewhere on the network. If you really want to be mean, you can choose Bulk for severely deprioritized traffic. Choosing Bulk will only allocate significant bandwidth when all other classes are not receiving traffic. This is perfect for a BitTorrent or FTP server on your network, as well as forcing a misbehaving user to come talk to you about reduced bandwidth.</span><br />

If so, I have been in your place at one time too. Since then, I have learned a lot about what a VLAN is and how it can help me. In this article, I will share that knowledge with you.</span></div><h3 style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">What is a LAN?</span></h3><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">Okay, most of you already know what a LAN is but let’s give it a definition to make sure. We have to do this because, if you don’t know what a LAN is, you can’t understand what a VLAN is.</span></div><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">A LAN is a local area network and is defined as all devices in the same broadcast domain. If you remember, routers stop broadcasts, switches just forward them.</span></div><h3 style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">What is a VLAN?</span></h3><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">As I said, a VLAN is a virtual LAN. In technical terms, a VLAN is a broadcast domain created by switches. Normally, it is a router creating that broadcast domain. With VLAN’s, a switch can create the broadcast domain.</span></div><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain.</span></div><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">Because switches can talk to each other, some ports on switch A can be in VLAN 10 and other ports on switch B can be in VLAN 10. Broadcasts between these devices will not be seen on any other port in any other VLAN, other than 10. However, these devices can all communicate because they are on the same VLAN. Without additional configuration, they would not be able to communicate with any other devices, not in their VLAN.</span></div><h3 style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">Are VLANs required?</span></h3><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">It is important to point out that you don’t have to configure a VLAN until your network gets so large and has so much traffic that you need one. Many times, people are simply using VLAN’s because the network they are working on was already using them.</span></div><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">Another important fact is that, on a Cisco switch, VLAN’s are enabled by default and ALL devices are already in a VLAN. The VLAN that all devices are already in is VLAN 1. So, by default, you can just use all the ports on a switch and all devices will be able to talk to one another.</span></div><h3 style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">When do I need a VLAN?</span></h3><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">You need to consider using VLAN’s in any of the following situations:</span></div><ul style="font-family: verdana, sans-serif;"><li><div style="text-align: justify;"><span style="font-size: small;">You have more than 200 devices on your LAN</span></div></li>
<li><div style="text-align: justify;"><span style="font-size: small;">You have a lot of broadcast traffic on your LAN</span></div></li>
<li><div style="text-align: justify;"><span style="font-size: small;">Groups of users need more security or are being slowed down by too many broadcasts?</span></div></li>
<li><div style="text-align: justify;"><span style="font-size: small;">Groups of users need to be on the same broadcast domain because they are running the same applications. An example would be a company that has VoIP phones. The users using the phone could be on a different VLAN, not with the regular users.</span></div></li>
<li><div style="text-align: justify;"><span style="font-size: small;">Or, just to make a single switch into multiple virtual switches.</span></div></li>
</ul><h3 style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">Why not just subnet my network?</span></h3><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">A common question is why not just subnet the network instead of using VLAN’s? Each VLAN should be in its own subnet. The benefit that a VLAN provides over a subnetted network is that devices in different physical locations, not going back to the same router, can be on the same network. The limitation of subnetting a network with a router is that all devices on that subnet must be connected to the same switch and that switch must be connected to a port on the router.</span></div><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">With a VLAN, one device can be connected to one switch, another device can be connected to another switch, and those devices can still be on the same VLAN (broadcast domain). </span></div><h3 style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">How can devices on different VLAN’s communicate?</span></h3><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">Devices on different VLAN’s can communicate with a router or a Layer 3 switch. As each VLAN is its own subnet, a router or Layer 3 switch must be used to route between the subnets.</span></div><h3 style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">What is a trunk port?</span></h3><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">When there is a link between two switches or a router and a switch that carries the traffic of more than one VLAN, that port is a trunk port.</span></div><div style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small;">A trunk port must run a special trunking protocol. The protocol used would be Cisco’s proprietary Inter-switch link (ISL) or the IEEE standard 802.1q.</span></div><h3 style="font-family: verdana, sans-serif; text-align: justify;"><span style="font-size: small; font-weight: 700;">How to configure VLAN on a Cisco Switch?</span></h3><h3 class="MsoNormal" style="font-family: verdana, sans-serif; margin: 12pt 0in 0.25in; text-align: justify;"><font size="2" style="font-weight: normal;">VLAN stands for virtual LAN and technically we can say, a VLAN is a broadcast domain created by switch. When managing a switch, the management domain is always VLAN 1, the default VLAN. All ports of switch are assigned to VLAN 1 by default. VLAN increase the performance of a network because it divide a network logically in different parts and limit the broadcasts.</font><font size="2" style="font-weight: normal;">Any member of VLAN 2 can not talk with any member of VLAN 3 without router but all the members of VLAN 2 and VLAN 3 can talk with other members within their VLANs.This Lab will also help how VLANs can be used to separate traffic and reduce broadcast domains. To create a VLAN, first enter global configuration mode to run the following commands.

The advantage of this type of Internet is that you can take it anywhere you want to, without having to get tied down by cables of wired internet. But one of the major woes that have been attributed to this type of Internet is that it cannot be shared with another computer in an easy way, or so it has been assumed. But the fact is that you can easily achieve it by using just a router, without any additional software. Here is how.</span><br style="font-family: verdana, sans-serif;" /><br style="font-family: verdana, sans-serif;" /><span style="font-family: verdana, sans-serif;">Before we start, there are certain requirements in the PC to be able to share USB dongle Internet. You will need a PC with one Ethernet port and a router (with Wi-Fi if you want to share the Internet over Wi-Fi). We are using Windows 7.</span><br style="font-family: verdana, sans-serif;" /><br style="font-family: verdana, sans-serif;" /><ul style="text-align: left;"><li><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><span style="font-family: verdana, sans-serif;">Open Control Panel by clicking on Start and Control Panel.</span></span></li></ul></span><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><br style="font-family: verdana, sans-serif;" /><ul style="text-align: left;"><li><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><span style="font-family: verdana, sans-serif;">Under Network and Internet section, click on View network status and tasks to open Network and Sharing Center.</span></span></li></ul></span><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><br style="font-family: verdana, sans-serif;" /><ul style="text-align: left;"><li><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><span style="font-family: verdana, sans-serif;">Click on Change adapter settings link located on the left of this window.

This is normal because the user name and password for USB dongle Internet is usually stored inside the dialer program that comes with it. Click OK to continue.</span></span></li></ul></div><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><br /></span><div style="text-align: justify;"><ul><li><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><span style="font-family: verdana, sans-serif;">Now you can choose one of the available connections in the drop down list to share the internet. If you have more than one network adaptors or Wi-Fi, you must choose the Local Area Network connection which you would connect to the router.</span></span></li></ul></div><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><br /><ul style="text-align: left;"><li><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><span style="font-family: verdana, sans-serif;">After you choose Local Area Network, click OK to save the internet sharing setting.</span></span></li></ul></span><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><div align="center"><br /></div><ul style="text-align: left;"><li><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><span style="font-family: verdana, sans-serif;">You will now see that the USB dongle connection icon shows that it is shared.</span></span></li></ul><div align="center"><br /></div></span>
<div style="text-align: justify;"><span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><span style="font-family: verdana, sans-serif;">Now plug in the RJ-45 jack at one end of a cross-crimped Ethernet cable into the LAN port of your computer (the same port which has been chosen for internet sharing), and plug in the RJ-45 jack at the other end of this cable into the socket market Internet on your router. It is a good idea to reset the router before connecting. It is also a good idea to make sure that the shared LAN connection does not have any IPv4 values pre-assigned to it, rather set it to get them assigned automatically.</span></span><br />

<span style="color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; height: 1%; line-height: 15px;"><span style="font-family: verdana, sans-serif;">Power on your router and connect another PC to its LAN port using another cross-crimped Ethernet cable to make sure that the Internet connection sharing is working. If you have any Wi-Fi devices such as a laptop or an iPod touch or a mobile phone with Wi-Fi, then you may want to rather use a Wi-Fi router. In that case, you can refer to </span><a href="http://www.techtree.com/India/Guides/Securing_your_WiFi_network/551-93219-560.html" style="font-family: Verdana, sans-serif;" target="_blank">this article</a><span style="font-family: verdana, sans-serif;"> to create a secure Wi-Fi connection.
