Latitude D630 Wired Connection Problem

Hello,

My ethernet connection device does not seem to be working. I already tried to trouble shoot it, but nothing worked. First, I have checked that the ethernet cable, and internet port are working properly. Then, i have looked in the device manager, and it indicates that my wired connection device are detected and enabled. However, when I connect a network cable to the ethernet jack on my laptop, there is no network light showing up. I have also updated the BIOS and wired network driver.

Please advise.

Thanks.
