Why does the computer not see the network card / local network?

Question

Computer networks

Good day to all. Now moved the PC to another room, closer to the router. Previously, the Internet was connected through a usb adapter. Now I put the PC right next to the router and connected it through a working cable (it works on another PC). After turning on the computer does not see the Internet at all. It does not even show the network card in the device manager.
