Ok my mom just got a cable modem today. I have dsl at my house so I'm not sure if i'm doing everything right. The problem is, the airport is not getting an ip address from the modem. I just un-pluged everything for 8min and still nothing(This is applecare said to do.) The modem works fine when hooked up to a computer direct. Anyone have any hints at all. This is really getting to me. Shes running 10.2.6 and all the newest versions of airport/basestation etc.
