I just recently built a new computer and was over at my grandpas housee when i did when I had the ethernet cable plugged in over there everything was fine. When I brought the computer back home for the first time I realized that the internet kept disconnecting and recconecting. I then tested my wifi and it was working fine and then I checked my xbox's internet which is connected to an ethernet cable and it worked fine too. I even triedd switching the cable but to no avail. Please help, i think this may have to do with the fact that i connected to mygranpa's internet first but I really have no idea whats going on.
