Need Help with Boot Camp Wi-Fi

Ok, I have a macbook PRO and im running boot camp. Everytime i get onto boot camp it says its connected to my wireless network. Then after about 10 minutes, it says "unable to connect to network" but i can still surf the web and stuff. But then I can't use the net and then i can again. But it doesn't say its connected again. I want to play Team Fortress 2, but I can't. I tried to reinstall the drivers for Wi-Fi but i keep getting an error when trying to reinstall them. Ill get a screenshot of the error if you guys want. So..... Thanks in return.

screenshot would be nice...

Wi-Fi works flawlessly for me using bootcamp
