If your 2Wire is functioning as the DHCP server, and has assigned your computer an IP address (and the LAN network light has gone green on the 2Wire) then you should be able to find the 2Wires address by looking at the Default Gateway address given to your computer. On Windows XP, you can see this quickly from a Cmd window by typing in IPCONFIG /all and look for the listing under Default Gateway. Try putting that IP address into your browser to access the 2Wire.

If your 2Wire is not doing DHCP (IE: It may be in bridge mode) and your computer cant figure out the 2Wires IP address (or the LAN Network light is not green) you will need to download and install a packet capture utility such as Ethereal (www.ethereal.com) and look for network traffic from the 2Wire.

Download and install Wireshark and then hook the 2Wire up via an ethernet cable directly to your computer. Start the packet capture on ethereal and let it run for a minute or 2.
Stop the capture and look for ARP messages in the form of:

ARP Who has zzz.zzz.zzz.zzz? Tell xxx.xxx.xxx.xxx

The xxx.xxx.xxx.xxx should be the IP address of the 2Wire. Say for example you see:

ARP Who has 192.168.2.111? Tell 192.168.2.254

This is the 2Wire at 192.168.2.254 looking to communicate with another machine (that likely does not exist, but thats ok.) Write that IP address down so you can try it in the browser in a moment.

Now you need to statically assign your computer to be in the same subnet as the 2Wire. That is you need to set your machines IP address to be like 192.168.2.5 (the .5 is just an arbitrary IP address) and a subnet mask of 255.255.255.0 That should allow the computer to talk to the 2Wire. Enter 192.168.2.254 into the browser address bar and see if the user interface comes up.

If it does not, in some circumstances you may need to try a netmask of 255.255.0.0 on your computer and then try 192.168.2.254 in the browser again.

Once you have the user interface up and running you can reconfigure your 2Wire to what you need, either by adjusting things or doing a factory reset and starting over.

  • Thanks. I was starting to think I bricked my router. This like will help with setting up the IP address: http://www.howtogeek.com/howto/19249/how-to-assign-a-static-ip-address-in-xp-vista-or-windows-7/ I looked hard for this info on Google & this page was the only thing close to what I was looking for which was exactly what I needed.
