Network cable not connected

[Tanvir]

Hello
I have a concern that I can not resolve, one of my PC to a network problem.
Indeed it does not seem to recognize the network cable that is connected.

The motherboard in question is a "775Dual-VSTA.
I add another NIC to the pc to see if it comes from the network adapter built into the motherboard and I am the same worries. The drivers are installed for time. Someone would have a miracle solution to see a track or seek some information.
In advance, thank you for your help.

You tested with another cable?
Or the cable on another pc?

You tested with another cable and another connector on your router (I guess you have a router)? It seems surprising but may need a crossover cable and you have a right one (or vice versa).

You have enabled the "LAN on board" in the bios?
Might be it only, but you never know.
But it would explain why the network card it would not work ...
So yeah the cable must be the culprit.

This error was popping to me for the last 2 months and finally found out that the culprit was the onboard NIC.
