no network today. It worked fine yesterday...
I'm running a new install of Kubuntu 10.04. I installed it a week ago. I'm using wired ethernet. Yesterday everything was working fine. I have not made any changes other than installing some updates yesterday. Today I have no network interfaces listed in ifconfig except lo.
But my network cards are listed in lspci.
What are the next troubleshooting steps? Thanks
ifup ethX reports the interface is unknown.
shows only the lo interface, not eth0 or eth1.
If using the GUI to launch KNetworkManager, the application doesn't open. Nothing happens. No error, but KNetworkManager just doesn't open.
(I've only been using KDE a short while. I'm not used to any of the tools.)
grep -i eth /var/log/messages
doesn't show any obvious errors. I can't paste the file at the moment because that machine has no network and the memory card reader isn't working (a hardware problem that's existed for a long time).
