So I just built a new system and my Ethernet port doesn't work. Can't install drivers because I get a can't find intel network adapter warning. I've taken my mobo out and ran it on the box it came in to make sure there's no shorting issues but still the same problem. The lights on the Ethernet port do not come on with a cord connected and I've tried multiple cords. Any ideas on what is wrong?

 
I've tried to install the driver from the msi site but ends in an error saying no network adapter found. In the device manager it doesn't show any network adapters except for the generic ones.
 
I've got the same issue on an MSI x399. I have a few other boards of the same spec but on one the ethernet is simply missing from the advanced menu in the bios as if theres no hardware element fo it. MSI were very unhelpful other than saying to get in contact with the reseller
