Solved: A network cable is unplugged (different)

Hi, I have read a lot on this problem, but still have it.

I have got an old Compaq Presario S5000NX. The original users, never used the ethernet network card (just as a standalone PC). I have reinstalled Windows XP Professional, and the corresponding drivers from the site; also, the latest BIOS. Everything looks in good condition in the Device Manager.

The Local Area Network Connection icon says "A network cable is unplugged" with the (working) ethernet cable connected. I changed all the options in the configuration and checked that everything is OK in the BIOS. Also, tried with another working ethernet PCI card, and the problem is still there.

Some suggestions? Thanks,

Augusto

 

Need clarification:

Does this mean the network connection is working but is falsely indicating that the card is disconnected?

Check Device Manager. Does it indicate more than one network device?

 

Thank you for your reply.

I have checked the connection using the onboard ethernet adapter and the additional PCI ethernet adapter with Ubuntu; and have no communication at all.

No, there is only one network device in the Device Manager. It is recognized as a "good" network card; the same is for the PCI adapter (when installed in the slot).

 

Just to make sure: you assume the cable is working because you've plugged it to another ethernet port and it worked?

 

Yes, I connect the same ethernet cable to a different PC, and the Internet comes up instantly.

And, when I install another ethernet adapter, it gets the same message (a different port).

 

Sorry guys, you won't believe this! I have changed 3 different network cards, and the 3rd one worked.

So, the problem was that the onboard ethernet adapter and the next 2 PCI network cards were defective.

Now, I can work normally. Again, sorry (it is the first time I've got 2 net cards failing).
