Okay, I have a 2Wire modem and service through AT&T. I also have an Airport Extreme base station for a computer n the other room where I cannot run a wire nor support a wireless card.
I cannot get the two to talk to each other. I can go wireless from my main computer (G4) to the 2Wire DSL (by unplugging the DSL's ethernet connection to the G4. I can access the internet wirelessly from the G4. I can see and configure the Airport base station (albeit not while connected to the other wireless network). I have configure the base station to go WDS and have the MAC address from the 2Wire in there as well.
When connected to the base station (as a client), it indicates that the IP is self assigned and does not connect to the internet.
How can I get my base station to act as a repeater/slave/client of my 2Wire DSL so that my other computer can surf/
