My internet is provided by a really cheap company, and it dies very often. On my old computer that was an annoyance that could be fixed by simply restarting the net. However, on my new computer when the net dies it doesn't come back. I can make it work for about 3 minutes by troubleshooting in the network and sharing center, but then it dies again and stays dead. If I restart the net it comes back just fine on the other computer. Does anyone know what might be causing this?
