My ethernet was working until yesterday. Next day I opened the system and it shows "Cable unplugged". I am currently using Ubuntu 18.04 but I also tried my old 14.04 but no ethernet connection on that either. Although Windows 8.1 can connect to internet via ethernet. I have tried 2 different ethernet cable connected to network on different ports.

I shutted down the laptop and removed the battery for 15 mins. Then it has started working.

Had a similar problem where USB did not work on a desktop computer. Shutted down and cut all electricity and it worked.
