Uverse, anyone?

Running Debian etch, and since getting AT&T Uverse service, I cannot
connect my T30 wirelessly to the "Gateway" - a combo modem, router - SSID
2wire341. I've tried w/ and w/o WEP, used different channels, auto
channel - I keep getting "No DHCPOFFERS received" from the Gateway. I am
pretty sure the set-up's OK on the T30 end, and don't know what else to
fool with on the Gateway. A Windows machine and an iphone do wireless
automagically.

The bad news is at http://rafb.net/p/xpwPCb36.html. If anyone else here
has Uverse and successfully set up wireless from Linux, I'm all ears.
