My desktop sees a connection but it says i have limited connectivity.
This is going to sound like a simple question and I don't wish to offend, just got to start with the basics and rule them out before getting more technical. You have set up DHCP on the LAN interface haven't you. The limited connectivity is a sign that you haven't picked up an IP address. Put a static IP address in the PC on the same subnet as your LAN interface. Then ping the LAN port on the router. If you don't get anything, try plugging the ethernet cable into the other NIC on your router just to be sure that you didn't make a mistake when assigning the ports.
