I have already ordered a new cable, as that is my first thought, however, this problem occurred when the cable was new and ceased happening for several months.
What the problem is, is my internet will drop out, saying that a network cable is unplugged. The way I fix this is to unplug and replug my cable repeatedly. Another thing that makes me wonder if it is actually the cable is that when I disable my network adapter and re-enable it repeatedly, it will also fix it. It's just more cumbersome that way. I don't think it's the network adapter either, as it's happened with multiple computers.
I've also had this problem across multiple routers and modems. The indicator on the router for the line I plug into is orange regardless of which port I plug it into.
