Lost Ethernet Connection

I am unable to connect to my LAN.  The error is "Unidentified Network - No Internet".  The system was fine on Friday, but on startup Monday the functionality is gone, although WiFi works to connect to the internet.  I require LAN access for connectivity to my NAS, so WiFi is only a stop-gap solution.

 

Troubleshooting has included:
Rebooting all involved devices.

Remove and automatically discover NIC in the Device Manager

ipconfig

Different network cable, different switch port

Windows & Intel driver updates

Onboard Devices in the BIOS

Recover (re-install) Windows

 

A few more random things in the middle of each of those, but I think you get the idea.

Model: BOXNUC8i3CYSM1

purchased slightly less than a year ago - but Intel has decided it's past End of Life, so won't support it......... even though it's still under warranty.

You may try:

1. Restart the Router.

2. Run the Windows build in Network Troubleshooter.

3. Disconnect the Power Adapter and the CMOS Battery and reconnect them after few minutes.
