Ethernet Controller Properties

I saw a thread similar posted by a user, Carri. But the solution posted for her didn't work for me. So here I go:

I built myself my computer which was a risky thing since I'm by no mean a connoisseur. But everything worked until I moved. Something in my SSD was preventing a full boot. So I erased it's content and re-installed windows 7. Everything works great when I go into wifi (via my Iphone) but my internet connexion is only wired. Whenever I plug the wire which I'm using now in my laptop (so the cable isn't the problem) the icon stays red with an X and says [Not Connected - No connections are available] (my laptop automatically detects the ethernet cable and connects without any problem).

I've done as much troubleshooting as I could with my limited knowledge and patience. Now here are some screenshots that will work better than words:






From what I can tell: I need a driver update. But I can't find it because I don't know the provider. Nor the driver's name. It's all unknown, or Not Available. Somebody knows what to do?
