Ok I just got an airport express, I have an older graphite G4 and I have been using a microsoft wireless basestation (i know, i know). I got this type of router b/c it "works best with xbox," ok i know i fell for it. All has been working fine, and I have no airport card. I got my airport express today mainly just to play music in my house. I figured it would work like my wireless xbox reciever, just hook it up and my wireless router would recognize it, well no dice. Nothing. Called up Apple, they said i needed an airport card. Is there anyway I can do this without an airport card??? Your help would be greatly appreciated. Thanks!
