Errors

uninstall the drivers for the wireless card then run windows live update the wireless card should be found and the drivers should d-load and then install themselves if that doesn't work try resetting your router or modem for the internet... sometimes certain computers in a house will receive a signal, and you might get the signal as well but the computers are messing around with the wireless... this happens more with belkin routers just restart the router and just run that one computer on the wireless network and it should start working. then you can allow all the other computers back onto the network
