My recollection is that I went out for 3-4 hours (today), came back and the Ethernet connection is no longer working. Wifi is OK.

I have an HP ProBook G1, running W10 Professional (and is up-to-date).

I have tried the W10 Troubleshooting, including some of these.

I don't know the name of the network adapter.

I have a NUC running W10 Home, in the same room. Tried switching ports on a D-Link 4 port powerline. The NUC continued to work.

Also shutdown, the HP, NUC and NAS and switched off the D-Link Powerline. No change.

Tried an Acronis System Image Restore to last nights backup, but still no joy.

I don't know what to do next.

Device Manager shows:
