Wired connection stopped working on Dell D620, help :(


I'm not currently able to connect through to my wired connection (though I was able to yesterday) but am able to just fine wirelessly, not sure what happened?

I get a light when the ethernet cable is attached & others can connect through the same cable just fine. When I go through Network Manger to try to edit the eth0 settings & click apply, I can see that it tries to negotiate a connection but after some time just fails.

lspci:
09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express (rev 02)
0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 01)

I'm on a Dell D620 running the latest Karmic Koala release;
Linux dell-laptop 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux


Any help that would get me connected would be appreciated.

Yes, but when you tried to get IP from router DHCP, can others did the came?

What is LAN address of the router?

Weird, doesn't show my eth0 now?

And if I try to bring it up;

sudo ifconfig eth0 up
eth0: ERROR while getting interface flags: No such device


What gives?

Looks like I discovered some strange Bug with this latest Kernel version, 2.6.31-14. When I revert back to previous Kernel, 2.6.28-16, I can connect through the wired network just fine
