okay i'll try explain it best i can being that i don't know much about this stuff..first of all, i have a 12" powerbook G4 connected to a linksys wireless G router wirelessly and also, a pc connected to it via cable. when i am running both computers at the same time on the internet, the pc seems to lose signal while the mac still has its wireless signal. also, the cable box that my internet service provider gave me seems to act different when the pc loses signal. the lights cable, data send, data recieve, and power stay constantly on while the pc light blinks..if anyone can please help me! this is so frustrating, i have to always keep resetting the router and the box..thanks so much to anyone who can help!
