msi Z87 G45 lan not working

Can anyone tell me how to solve this? I have tried multiple cords but none of them register as connected. I have the killer network program by the way.

I've had to replace at least a dozen LAN ports on that board with LAN cards -- the Killer NIC sucks.

The easiest and best solution is to add an Intel gigabit NIC, specifically THIS ONE, which is the most stable best card available.
