Help! I have a G4 1GHZ laptop running 10.3.5 with a airport card in it, I dont think its the extreme one. Under system profile card type is: AirPort Firmware 9.52. Everything seemed to be working fine at my brothers place using his wireless network. I think someone at his place changed the setting to do a computer to computer network.. Now for some reason I cant connect to any wireless network it doesnt even see any of them (home, school). I dont know if the card is bad or what the strange thing is, in one of the buildings I have class in, it finds a linksys network using netstumbeler and shows that the signal is strong and says its a computer to computer connection, but in the upper right hand corner of the screen were the airport icon is it doesnt show any signal even when the linksys network is selected, I get no green bars for the signal strength. Ive tried everything I can think of other then re-installing the OS, which I really dont want to do. Is there any utility out there that can reset the airport card?? I zipped the PRAM and that didnt work. Any help would be grate!
