ok I was trying to setup a network between my pc upstairs and my iMac but apparently I accidentaly disabled my airport card... The Aiport is recognized by my Dell PC, iBook, and (iPhone via wifi) but my iMac can't find the airport.. when it searches for airports nothing comes up... I don't really wanna go to the Genius bar =/ I am just assuming I somehow disabled my built in Airport card so does anyone know what I can do? it says i'm connected to the right Network but the airport doesn't come up when I search... any help? Thanks!
