yeah, i have the original white Airport Basestation (Not extreme) and i've tried resetting it and the modem. I even did a hard reset on the Base station and reconfigured all the setting and still no luck. I've also tried plugging straight into the cable modem and I get the same problem.
What's even more baffling is my girlfriend subscribes to the same cable provider (Rogers in Toronto btw) and when I bring my PowerBook there it works fine.
Oh great show btw...I've been a faithful listener from the beginning!!
