Hey guys! I recently dropped my powerbook g4 and I think it broke my airport card since my mac could no longer detect it. I'm wondering how i can change the computers airport card without costing me a fortune. I purchased a minu usb wireless adapter from Fry's yesterday but it's really not working that well. Is there any advice you can give me? will it be better to change the card ( if there is one built in the computer) or just purchase a usb wireless adapter? Thanks for the help!
