How to repair a faulty ethernet port?

I tried uninstalling the drivers and reinstalling but that did not work. I'm using Windows 8 and a Lenovo G50.

Have to ask… The ethernet cable.did you try that cable on another computer to make sure the cable is not faulty? If the cable is good. When you go to plug the cable in, you should hear it click ( that means it is firmly seated )…

If the cable is good and when plugged in it is firmly seated and your not having and modem / router issues and you do have access to the internet… Sorry to say you may have to contact lenovo support…
