To remedy this problem, I must deactivate / reactivate the WiFi card and the period of freeze again after 30min .When this occurs freeze period, the connection to the access point is muted. . I said that I have this problem on Windows XP, Windows Vista, the connection is stable, it impact 'with the same driver ...
