I'm not sure if this is a hardware or software problem but in a fit of spring cleaning, I disconnected my desktop yesterday.
I connected it back together today but can't connect to the internet. I tried the diagnostic (in Windows 10) and it thinks I don't have a network cable plugged in. However, it's connected to my BT router with a cable and my other computers are working ok, so there's nothing wrong with the router. I tried different cables just to make sure it wasn't a faulty cable but I get the same result every time.
Curiously, the orange light next to the cable connection isn't flashing at all.
Could anyone help me identify the problem?
