I have a belkin 802.11g wireless card hooked into my desktop PC and it constantly drops signal and often won't reconnect until i disable the connection and the re-enable it, though this always works. The wireless signal is broadcast by my university and my flatmate receives a steady signal in the same place as my desktop. I tried to update the drivers, but had problems with that. I was wondering if anyone please has any suggestions for me. The specific message it gives is the "wireless connection unavailable" and every so often it goes to no signal and then drops off for a longer period of time. Thanks for the help
