I recently got an iMac G4. It had no wireless, and since that's what I use I bought the (correct) Airport Express Card. I installed it without a hitch, and it seemed to be working fine, until I reinstalled Leopard. Now every 2-3 minutes Airport will simply drop the connection. I have no idea why. I have updated all the firmware, but it continues to drop the connection. Can someone please help? I should also note that I'm on a MacBook right now that hasn't dropped the connection to the same wireless network.
