I have a Gateway laptop. It is connected via ethernet cable/modem. I am also running Windows 7. For some reason, when I leave my laptop on over night, it drops the internet connection. I don't know what causes it. It is frustrating because it is trying to create a new network connection that does not work. So, I have to disable, and delete the new network (which is called NETWORK by default). Then re-enable my old working network connection. This fixes it every time, but is very lame to have to do. How can I fix this?
