ethernet problem

[marhleet]

wasn't it in the header of the forum........

what does a lspci show, as it seems the nic has failed, does it still show ?
also, with the cat5 plugged, does the port light up to show net detection ? this also shows on the router end.
apart from if it is alive and lighting, it might be still dead inside, lights on, no-one's home.

in the router, does it have an 'attached devices' option to show the DHCP is working?
in the logs (fingers crossed) can you see the mac address requesting an IP.?

If you still haven't resolved this yet, try swapping the outlets on the router/hub. Plug the network cable of the knoppix computer into one of the outlets of the working windows machine.

I have seen a failure on a combined router/hub before (also after a power cut) where a particular hub outlet was faulty
(no connectivity) even though the LED against the port indicated a connection.

Problem solved.

I inserted a new network card and got pretty much the same error messages that
I received with the existing network interface. So I went back to assuming the
problem is software, not hardware.

Then I started looking for some network control in the window manager and found
knoppix->network/interface->network interface configure (note: I'm not on the
knoppix pc right now, so I may not have the exact names in the menus correct).
I configured the network card and ran 'route add default gw 192.168.1.1' to map
a route to my router. And then everything worked find.

Bottom line is that when I lost power, I lost my network interface card configuration
and I forgot to reset it.

Thanks to everyone for adding their thoughts and suggestions.

Thanks for the update and it's good to know that the problem is resolved. The thing is, I've very confused about what you just said and I would like to uderstand it better to be able to help others or in case I ever run across this myself. You're talking about some sort of setting, apparently to Knoppix, that I've never had to do. And in your very first post you started this whole discussion with

I've been running Knoppix 3.7 from CDROM on my PC for about 2 months. .....

I've always been able to boot the Knoppix CD and it's set itself up by DHCP. We don't need no stinkin' "route add default gw" command. It has worked this way for me on several different computers and on maybe a half dozen different routers. So I'm hard pressed to understand why booting from a Live CD you need this command (and how you even determined that you need it). And why when booting from a live CD you would not do this each time, if you have to do it at all.
