    Can you see the LAN controller in your Device Manager of Windows ? If yes, then the LAN chip is being seen by the motherboard. That is a good start.

    Check the RJ45 connector pins that you use for mating the Ethernet cabling. Do any of the pins look bent to you? The connector may need to be replaced.

    Otherwise, you will have to open up the laptop to inspect near the LAN connector to check for possible high transient damage that is possible for this port.

    A quick fix is to just source a low cost USB Ethernet dongle. If you do this, source a USB 3.0 to Gigabit dongle (Asix or Cypress are good chipsets).

      Windows sees it in the peripheral list and visually disassembling it, everything looks ok even the connector pins. I'd rather fix it

        Do you know the history of the laptop , was the bios flashed recently.Is the LAN disabled in bios settings. Can you boot from linux and get a MAC address

              Glad you managed too fix the issue it took me a few hours too figure it out myself, this happened when updating a pc to windows 10 it was working fine on wireless but i like too make sure all ports etc work before i pass a pc on.
