Ethernet Connection is Not being detected in Windows 7

I have faced a problem just a few hours ago for the first time that my Ethernet Connection is not being detected.

I have a Lenovo essentials b570-e laptop, with a core i5 processor and 2 GB Ram.

I have never before experianced this problem. I have already tried via another cable, connecting it from the other way and stuff like that. It works on my Brother's Laptop. I also know for certain that is it not a hardware issue as I have tested it on a live boot from Ubuntu 11.10 that I had lying around and the internet worked perfectly fine. So I know that the problem is with windows.

Can someone please help ASAP.

Any replies are most welcome and Thanks in Advanced :)

Have you updated your drivers recently. If so roll them back to the previous version.

If not look at your manufactures website for the latest drivers.

Does it get detected in windows mode with networking?

Hey.

Have you tried the basics.

Check device manager, to make sure Driver is installed correctly?.

Also check for a driver update.

When you plug the CAT5 Cable in, Does it say: "Network Cable unpluged"? Or limited or no connectivity?.

Are you running DHCP (router) or Manual IP?

Yeah I just checked device manager and it turned out that it was disabled Thanks for the reply :)
