whose your ISP? I strongly suggest caling them out to get it checked since it doesnt seem like you know too much about it, feel free to correct me if im wrong and i can kind of direct you what to do. But it sounds like your ISP-router keeps disconnecting you/resetting itself. Mine will do it often, ended up eliminating a splitter not long ago and it has stopped. Although it starts up again sometimes when the weather is crappy.
