I just installed an Airport Extreme Card for my Dual 2ghz G5 PowerMac. I have a Linksys Wireless Router in my house that works fine w/ our other laptops, etc. For some reason, none of the dozen or so wireless networks in the area show up. The airport card seems to be hooked up fine, and is being recognized by the OS, but no clue on how to get my networks to show up, even if I type the network name and password in. Is there something I'm not configuring properly? Or is there something I don't know about compatibility between Airport cards and 3rd party wireless routers? Thanks for any help out there.
