    Hi guys this is my first post here, anyway heres the problem.

    Basically I cannot connect my laptop (using it right now to type this) to ethernet. I currently have the ethernet cable plugged in to the router or modem (i know its not working i tried both dont worry). I have opened my laptop before, to fix my overheating issue. I sometimes see when i try to do some stuff to fix it ethernet might go on rarely (happened today) like on and theres no red X around it and I can see it's there but then it goes away. I am going to post a ipconfig /all with it plugged in. (attached file). I can use wifi but I cannot use ethernet. Im using windows 8.1, a realtek pcie fe family controller as the ethernet but it says "network cable unplugged". Its been like a week trying to fix it. I will try anything you guys can suggest.

    You've tried with the wireless disabled, right? And tested the cable with another computer?
