I have an iBook G4 14". I am running an Apple Airport Extreme with Cable modem. I can not get a good connection since I moved. I have the same broadband provider. All was well until a few weeks ago when I woke up and I had no connection. The laptop will work with Airport away from the apartment. I can not connnect with ethernet or airport at home. The airport shows a strong connection yet there is no actual. I have connected the modem to a PC and I am able to get cable to work from modem not the airport. Thank you.
