Hi all,

I have a Lenovo 3000 N200 notebook which has been working fine for the past month with Ubuntu 8.04. Last night when I went to bed I suspended the laptop. Upon resuming it this morning I had no network connection. After some investigation I found that the eth0 device wasn't being listed with the 'ifconfig' command. I tried doing a '/etc/init.d/networking restart' and rebooting the laptop, but eth0 doesn't exist.

Please could someone help me sort this out? It's really frustrating :(

Thanks,
G

Is Ubuntu set up to download and install updates without needing your approval?

Thanks for the replies. Here's the output from dmesg and lspci:

However, I'm worried the problem is much deeper. I booted off a live Ubuntu CD (8.04 too) and I get the same problem. I've never encountered HW failure on a NIC card? Especially considering the laptop's only two months old. Any ideas....?

I suppose it is possible that the builtin Ethernet port went bad.

Usually when a cable is plugged into mine there is a flashing green light.
Or just a steady green light when there is no traffic.

I do get a green solid light, and a flashing orange light....

Can you go into the BIOS. Disable the NIC. Boot with Ubuntu.
Shutdown your machine completely.

Then go into the BIOS. Enable your NIC. Boot with Ubuntu.

After that post the output of the following :


lsmod
lspci
lshw -c network
dmesg
ifconfig -a
route -n
cat /etc/resolv.conf

Please post here as output.txt attachment(s).
