My built in Ethernet card decided it was going to quit on me. So I popped in a new Ethernet card, my only problem is that ifconfig eth1 up does not work with any other that eth0 even though that built in one does not work. I tried turning off in the bios, Nothing is working. I was wondering if this is a simple hardware failure with a simple solution.

PS.

I have tried 2 live cds the gentoo one and linux mint, same issue.

Hi -

I believe the solution is to configure your working Ethernet as eth0.

Turning the failed on-board NIC OFF in the BIOS is a good start, but, as you've discovered, isn't necessarily the whole solution.

Once you boot into Linux, you should be able to DELETE your current eth0, then RECONFIGURE the working Ethernet as eth0 from the GUI (e.g. from Network Manager).

Failing that, you should be able to edit the appropriate files under /etc/sysconfig/network.

If you're booting only from Live CD (and haven't installed anything to hard disk), all bets are off as to what can or will persist between reboots

'Hope that helps .. PSM

ifconfig eth1 up does not work with any other that eth0

It is telling me you need a driver for the new nic.

I feel really stupid, I just unplugged my switch then blew out the dust and it worked again. I think the contacts must not have been in contact with each other. Sorry for wasting you time for this simple solution. Though I did find that the built in one was really broken.

I may have been misleading, this was the gentoo machine sorry.
