I have run into the wierdest problem with the internet connection i have ever heard of. Heres the basis: I have a powerbook, g4, which was connected to a wireless g linksys router. I had a connection, than one day, (three days ago) i couldnt get access. The internet is still up, as the other pc laptops that my roomates run can connect, but mine and my roomates (macbook) cant get a connection. I go into the network settings under system prefs., and it says: Aiport has a self-assigned IP address and may not be able to connect to the Internet. I have tried the basics, testing every setting available, renewing dhcp lease, restarting the computer holding apple option r and p, but i still cannot connect. The airport card is not broken however, because i can connect to the internet when i go to school and other hotspots, (coffee shops etc.). When i plug my computer into the router, it has the same problem, and when i connect the computer directly into the modem, bypassing the router, i STILL have the same problem. I finally gave up and called apple support yesterday, and after an hour of working with some guy, (who provided me with no extra support than the manuel had), he finishes the conversation saying to check the internet forums for the answer, as there is no known reason why this would be happening that he could think of. And i did update my airport software yesterday. Im really hopeing someone here can provide some help, because myself, my roomates, my prof, and the apple support can not figure this out. Thank you very much!
