T410i: Frequently disconnection of ethernet

[qbektrix]

I have Thinkpad T410i+Win7Pro and I did a clean installation (installed win 7pro, the ethernet driver and then thinkvantage that installed all the other drivers).

Now the issue is that the ethernet is frequently disconnecting and reconnecting automatically. I did download the new driver from Thinkpad site and when i try to install it, I am told that the same version of driver is already installed. When i try to uninstall that driver via the device manager, even though i select the option to "delete software for this device". It automatically installs the driver as soon as I uninstall the driver.

What can I do? Is there any log for ethernet that will tell me why am I getting disconnected? There is no issue with the wifi.
