"network cable unplugged" error on new computer. No port lights

[sonn]

Hello. So I've been trying to fix this for two days now. My onboard lan is a Realtek pcie gbe family controller, and it's been giving me a "network cable unplugged" error since The beginning. There are no green or orange lights on the lan port, ever. But the network device does show in the device manager. I've updated the drivers for everything using a usp storage device and it's still not working. I've done all the basic procedures, connect/disconnect/shutdown/restart/ uninstalled and reinstall drivers/enable realtek in bios. It seems to me as long as there is no light on that port, it just won't work, even if Windows recognizes the lan port. I'm using Windows 7. The motherboard is an asus prime b350. Please, any help would be wonderful. I'm losing all hope here.

A different cable is not one of the troubleshooting steps listed as having been tried.
