This past couple of month's have been very frustrating with going over data usage. We usually come close to the wire the last few day's and use about 1% a day. But for some reason within 2 week's we are at 85% nothing has changed with our internet usage. We got up to 105% so I shut the modem off for a week until it rolled over into the next month and when I turn it back on We somehow managed to jump from 105% to 111% with absolutely no internet use... How is this possible???
