I have a Toshiba Satellite a75, and I have started to lose my wireless conncetion intermittently. When I try to reconnect to my wireless network, it will (it takes about a minute to do so), and then 5-10 min later it is on longer connected. My roommates all are accessing the wireless connection without a problem on their laptops. I have tried to download the newest wireless drivers from Toshiab to no avail. Any help would be appreciated.
