[Solved] Ethernet not working on SIERRA!!!

Hi!
I installed Sierra and all drivers for motherboard, but ethernet is not working. I tried to install all different drivers from multibeast.
Also usb 3 ports are not working only usb 2.0.
I installed Nvidia fix in multibeast and it looks ok, but i am not sure how to check if its ok.
I am guessing audio is ok but not checked it yet.

My system is:

Gigabyte GA-Z87-HD3 rev.1.x
Graphics: Nvidia GV-N670WF2-2GD | Graphics Card - GIGABYTE


Tnx
