Will WPA2 work at all with the original AirPort Card? On my Cube and 2002 eMac they know what WPA2 is, but when I try to connect to my network via the AirPort Card, it says it cannot connect to it.
With the G4 DA if you want an external USB adapter, make sure you have either a USB 2 card in, or you get a USB 1.1 compatible wireless adapter. I tried an N USB Wi-Fi adapter from ASUS on the eMac running 10.4.11 (needed min. 10.3.9), but said nothing about needing a USB 2.0 port, and it didn't work properly.
