I have a laptop, an ethernet adapter, windows 10, and I'm using a cable box as a source of connection. It has an ethernet port.
When I diagnose ethernet in Network Connections it says "Plug an ethernet cable into the network adapter." Then I click check to see if the problem is fixed it says "An ethernet cable is not plugged in or might be broken."
