It doesn't even show the LAN controller. I've never had problems with it under Windows either, Ubuntu just doesn't seem to be able to see it for some reason.

It doesn't even show the LAN controller.

Quite correct. Please post:

dmesg | grep -i warn
dmesg | grep -i error

You might also look around in the BIOS to see if there is a setting you can change to get the LAN recognized.

God I feel stupid...for some idiotic reason I must have turned the LAN controller off in BIOS, because that was all it was! It's working perfectly fine now...pebkac strikes (me) again again...

Thanks a ton for your patience and help chili555!

Hi, I'm having a similar problem. My old HP pavilion ze1110 works fine with everything up to Lucid. Once I reboot after install the net drops out. I'm using a belkin F5D5050 USB adapter which was working fine. I've tried to check the BIOS but all I can see are a date and time control, processor and memory info, noting else. I don't have a disk to reinstall from yet. This is the second time this has happened. I also got the "No network device detected" warning. what's going on? Is my machine just too old?
Thanks

As this has nothing to do with an Intel wired ethernet card, I'd suggest you start a new thread. Please post:

Thanks.
