I have dual boot (Ubuntu 16.04 and Windows 10) installed on my laptop.
I found out, that when I shut down Ubuntu and run Windows then often happens that network cable stops working. I usually restart the laptop then and then it starts working (sometimes two restarts are needed) or I disconnect cable, shut down Ubuntu, run Windows and connect cable.
I know that earplugs do not have to work when you are on Ubuntu and then restart and run Windows (if you shut down Ubuntu and run Windows, they are OK). So I think that this may be similar problem.
Does anyone experienced it too? Some fixes?
