You should pick a non-overlapping channel frequency for better performance [Fig. 5]. Channels 1, 6 and 11 do not overlap with each other in the United States. For example, if your repeater is broadcasting on channel 7 you can select either channel 1 or 11 on the second router. Everything will work even without proper channel assignments. This is just a precaution to avoid interference.

Also type in the SSID. This is the name you will see when connecting to the router wirelessly. It should be different from the SSID of the repeater.

The last and the most important step is to go to the "Setup" tab [Fig 6]. Under "Basic Setup" we'll change the "Local IP Address" to place the second router in the repeater's subnet. In this case the repeater IP is 10.0.0.1 so I changed the IP address on the second router to 10.0.0.120. The last place number (120) can be any number smaller than 255 and other than 0 or 1.

Select "Disable" under "DHCP Server" on the same page.

At this point you are ready to connect to the internet as long as the repeater is working properly. The LAN ports on the WHR-G125 and the wireless connection are both available for use at this time. You can still access control panels for each router by entering their respective IP addresses into a browser. In this case 10.0.0.1 takes you to the repeater's GUI and 10.0.0.120 takes you to the Buffalo router.
