My z170 deluxe have 2 lan ports. The upper one works fine but the lower one can't be connected. When I connect cable to it, the light blink normally but the window didn't see it.
Easiest way is to read the manual, but you must have both drivers installed for both to work. Go to devices and check which one you have installed. Use the newer one obviously.
But you would think every time you boot you would get a found new hardware dialog if it is a driver missing.
One way to check might be to reboot with the network cable in the nonresponsive port

I did try install the missing driver before posting this question and for some reason it froze my PC.
