internet died after ubuntu 16.10 upgrade

internet 16.10

Please help me, I am tired of googling. After upgrading from 16.04.01 to 16.10, my wired internet connection just died. (It is by Ubuntu, because I've dualbooted with Windows using the same connection).

Please help me - What should I download from where? And what should I type into the commandline - I am a Windows programmer, but a Linux noob

This is 'the info' of everything I googled after seeing my internet connection die, it should contain the information needed.

Thank You very much, I am actually in the process of testing Ubuntu to forget Windows forever.

Solution 1:

Modify your interfaces file:

sudo nano /etc/networking/interfaces

auto lo
iface lo inet loopback

auto enp9s0
iface enp9s0 inet dhcp

Save your changes and restart.
