Wireless wont work... possibly corrupted.

Hello,

I have an ASUS U-81 Laptop and as of late my wireless capability will not turn on. I have tried the switch, I have tried Fn + F2, but it does not seem to work. I troubleshot the problem, but it told me it couldn't diagnose the problem. I went to additional information, and it said my wireless was turned off. As if I didn't know. I tried to do a system restore to a few days back when it was working, but it tells me that I have a file system corruption. It asks me if I wish to check for errors. I say yes, It tells me that next time it starts up it will check for errors. So I restart it and it did nothing of the sort. I try system restore again, and it gives me the same message. Help, please?
