Dell XPS 8700 Desktop i7-4790 16GB RAM dual boot Win 10 home / Ubuntu MATE 18.04.1

Win 10 installed on 1T HDD, UM on 120GB SATA SSD

When booted into Windows, both WiFi and ethernet connect

When booted into Ubuntu MATE, WiFi connects but ethernet will not.

I am not very experienced in linux CLI and seek guidance from those well versed in linux and networking.

If someone is kind enough to assist this old guy, it will be much appreciated. Please let me know what information I might provide. The necessary commands will be very helpful.

Same problem here.
Ethernet connection suddenly gone. Switched to Wifi, can’t reconnect to ethernet even after reboot.
