My 800mhz iMac is having serious troubles with Airport connectivity. It is literally sitting right next to the base station and picks up no signal. My Pismo Powerbook is upstairs and has huge signal. I tried restarting the iMac, base station, changing channels, moving the base around with no change. Do Airport cards go bad over time? My theory is that it's either the card or the antenna in the iMac. Any help would be appreciated.
