Public bug reported:
This was working perfectly on 17.04, but after installing 17.10 from
scratch, the wired network is not detected. It simply shows as Cable
Unplugged when in fact there is the same cable still connected directly
to the router. This same computer has Windows 10 and it detects the
network correctly. I also tested Fedora and it detected the network
correctly (The wired one). I am currently using only the Wireless
connection because of this.
