I brought my macbook (white 13 inch bought in early 2008) to a repair shop I had used in the past in order to have the screen replaced since the the inverter board was failing. My screen is nice and spiffy however... First the repair person could not get my computer to boot and claimed that my hard drive was failing. When I turned over my computer to them, it was booted up and I've had no issues that would hint the hard drive was failing. So the guy wipes the hard drive and reinstalls snow leopard (Don't worry--I use time machine). Now my airport card isn't working properly. I can only connect to the wireless when I'm standing two feet from my router, but the wireless works fine with my iPhone. The repair guys is claiming that everything on my computer is just failing at once. I'm not a hardware person so I'm having a hard time telling if this guy is full of crap and if so how to tell him that. Advice please?
