I currently use Airport Extreme router(old model) with firmware v5.7 and configured it with WEP 128 key. However, WEP is easy to hack. Is there a tweak that allows 2002 iMac G4(Mac OS 9.2.2) with original Airport card connect through Wi-Fi with router configured with WPA or WPA2? I cannot use Ethernet, cause only LAN port in my router is occupied by cable, which is connected to my PC.
