HP ProDesk 405 G4 Base Model Desktop Mini PC
Microsoft Windows 10 (64-bit)

Hi, I have problems with Realtek PCIe GbE Family Controller on HP ProDesk 405 G4 Base Model Desktop Mini.

PC does not see the network, there is no connection with the router.

NIC fails the MAC Loopback test in Realtek Ethernet Diagnistic Utility.

I wanna hear your thoughts, dear colleagues.
