			<content:encoded><![CDATA[<p>Here are the settings for if you want to replace the standard o2 Thomson modem/router with the Netgear DGN2000. These should be entered into the web interface.</p>
<h3>Setup / Basic Settings</h3>
<p>Does Your Internet Connection Require A Login? No<br />
Account Name:  Blank<br />
Domain Name:   Blank<br />
Internet IP Address: Get Dynamically From ISP (If you have a static IP address, enter it here).<br />
Domain Name Server (DNS) Address:  Get Automatically From ISP (I&#8217;m actually using the OpenDNS servers, so I have entered 208.67.222.222 and 208.67.220.220)<br />
NAT (Network Address Translation): Enable<br />
Router MAC Address: Use Default Address</p>

<h1>Routing Issues</h1>
<p>Unfortunately, I suffered intermittent routing issues &#8211; other users have reported similar issues in <a href="http://forum.o2.co.uk/viewtopic.php?t=22311">this thread</a>.</p>
<p>Thanks to wilderbeastie, there is a workaround detailed <a href="http://forum.o2.co.uk/viewtopic.php?p=140379#140379">here</a>:</p>
<h2>Option One</h2>
<p>1. Enable telnet access in the router.</p>
<p>http://192.168.0.1/setup.cgi?todo=debug</p>
<p>2. Login via telnet to 192.168.0.1 (via putty or the command line)</p>
<p>3. Run the following command: -</p>
<p>&#8220;echo 0 &gt; /proc/sys/net/ipv4/neigh/nas0/ucast_solicit&#8221;</p>
<p>This setting doesn&#8217;t survive a reboot so needs re-applying every time.</p>
<p>If you suffer loss of routing, this procedure also seems to restore it (i.e. you shouldn&#8217;t need to reboot first).</p>
<h2>Option Two</h2>
<p>This is exactly the same fix as detailed in option one but the command is inside the following link &#8211; all you need to do is copy &amp; paste (all one line) into your browser and enter the username and password: -</p>
<p>http://192.168.0.1/setup.cgi?todo=ping_test&#038;c4_IPAddr=%26/bin/echo%200%20%3E/proc/sys/net/ipv4/neigh/nas0/ucast_solicit</p>
<p>Again, this fix doesn&#8217;t survive a reboot.</p>
<h2>Option Three</h2>
<p>James from ADSL24 has patched the standard firmware to run the relevant commands on startup of the router.</p>
<p>The downloads are <a href="http://adsl24.co.uk/forum/showthread.php?t=7628">here</a>.</p>
<p>This method will survive a reboot.</p>
