can't find nic, help needed

Post by lucifer663 » 2013/09/25 15:22:53

i was using two ethernet cards (one onboard - rtl8111/8168B and the other pci) on my centos box, i did not use any extra drivers when setting the system up. from yesterday, after a reboot, the onboard nic disappeared. the pci lan card is now recognized as eth0 and it works fine (accessing net from that at the moment). any help will be appreciated. note: i cant afford to reinstall the os, ( have some 3rd party licensed softwares in it). tried installing official drivers from realtec but did not work.

info:

Welcome to the [i]CentOS[/i] fora.

Please show the output returned by the following --

[code]
[b]lspci -nn | grep -i net
rpm -q kernel | sort
uname -r[/b]
[/code]

I am sorry but it seems like bad news. :-(

As the original NIC is not showing in the [b]lspci[/b] command's output, it looks like a hardware malfunction.

Do you have any Manufacturer's diagnostic programs that you could execute to test the motherboard?

Also check your BIOS settings and make sure that the on-board ethernet controller is enabled.
