ok guys and gals here is my problem. I just got my 12' powerbook a couple of days ago along with that came an airport extreme basestation with no modem. For the first couple days i had no problems setting everything up and getting on to the internet but suddenly the other night my wireless stopped working. here is my setup: Comcast cable modem sends its connection to a linksys router and two computers and the basestation connect to the router. everything can get online if its connected by an ethernet cable, including the laptop. The laptop can even connect to the basestation via a ethernet cable. But for some reason it doesnt recognize any wireless networks. I've tried resetting the basestation, reconnecting wires, having the cable modem go to the basestation first and then have the router connect to it, but still nothing. If anyone could give me a little help that would be greatly appreciated. thanks in advance.
