One pc can ot connect to the network. All other computers can connect using wi-fi, lan cable and network plugs. The pc in question can connect to the internet through the network plugs but I understand the plugs are assigned the i.p. and not the computer connecting through them. When the pc is connected to the router by a lan cable a message says network cable unplugged. Have tried restarting router, ensured all of the settings in windows and on the router are correct. Diagnostics of the connection results in a message sawing "warn network adaptor status not healthy" among other things. What does this mean?
