I bought an AirPort card (not AirPort extreme) for my iMac G4. I can't connect to my WPA2 network. I didn't realize this would be a problem until later. The iMac G4 is running 10.4.11. Is three some sort of update I can get or hack I can do so I can connect to the network? I know I can lowed the secuirty on my router to WPA but I don't want to unless I absolutely have to. Any help would be great.
