Thanks Dave, but I alread went through all the error codes. I have to assume my 2WIRE modem/router is just incompatible. I found this thread here that describes the same problem I'm having:

I've had my modem/router for four years now and it is no longer supported by AT&T/Cingular.
At this point, I think the only thing I can do is first make sure a TMo HotSpot works first. If it does, I think that pretty much rules out the BB as the problem. Hopefully I can talk AT&T into sending me a new modem/router. That should be fun.
