My internet connection stops working after either a few hrs or a few minutes. It appears that this happens because of a lack of activity and also more at night than during the day. The office computers are all HP notebooks confiqured to run wirelessly. This happens with only one notebook. It seems to have happpend when mozy.com was configured for unlimited backup. I do not have ZoneAlarm and never had. When conputer goes off line then I need to reboot.
