i've searched for help in this forum on this, but no one seems to be having problems.... As far as i can see, all i have to do is put the card in, turn on the mac, open safari and it should automatically see my airport extreme and be happy. however it isnt being recognized. even in airport utility my AEBS can't be found. please help because i think i might have wasted 50 bucks. just to clarify. i have an airport extreme and express in a network that my Macbook Pro is connected to wirelessly. The G4 with the new card installed cant see a thing. It works fine when plugged straight into the AEBS.
