I have a 2008 MBP and every time I try to connect it to a wifi network the airport will turn off on me. I will admit it has been a rough life for the poor thing. With 2 years in Iraq and a few dents in it, I am not surprised that I am having the problem. Everything else works great on it. I have tried to reboot. I opened the computer up and reseated the card with a little luck. My next option is to buy a "new" card for it. I have seen them out there for around $90 or so. Does anyone else have any ideas or is the new card the best option?
