10.04 wired connection stopped working

[Worp8d]

Hi,

Installed 10.04 (fresh) on my media centre, everything worked fine and has done so for a week now. Turned it on today and there's no connection to the router. The router is fine as I'm connected on my laptop through it now. Pretty sure the cabling is fine (have checked it and have no reason to suspect anything has damaged it in the last 24 hours). I suspect an update has changed something but I don't know where to start looking for and fixing the problem. Anyone got any ideas?

sudo lshw -C network detects the network card and everything there looks normal.

If you use DHCP, post results of sudo dhclient eth0

Well, now we know why the connection isn't working... now why DHCP isn't working. I'm a bit curious if the highlighted text is a typo, or if the system is doing something weird.

Yeah I'm sorry, the 'etho0' should actually be 'eth0'; with not network connection I'm having to copy commands/responses off the screen.
