[ubuntu] Internet working in live mode and during installation, not after installing.

Okay, so I have Windows 10 and attempted dual booting Ubuntu 16.04 with it. Everything went fine and I used EasyBCD to get to Ubuntu (I wanted to avoid overwriting the windows MBR for safety). The problem? I had no inteet even though it took all the updates during installation and worked in live mode (Also tried installing w/o updates as I thought an update was the culprit). I checked my router and the lights indicated it was sending a signal + It works without issues in windows 10.

I moved away from Ubuntu and tried Linux Mint 17.3 (Yes, It's based on ubuntu, but as far as I know, it isn't as up-to-date). The scenario was exactly the same... Any clue what's up?

My motherboard is an MSI Z97 SLI Plus. All help appreciated, thank you very much.
