Bad Ethernet on O2

I've got an O2, came from a dumpster outside of Columbia University. Machine was "Bronk" in the music department.

Anyway, it runs just fine on 2 gig HD and 64 meg RAM, but...

The ethernet connection seems to be dead, no connect lights on my hub/router, never negotiates an IP address from DHCP. Nada

How many times, if ever, has anyone seen this? And assuming not a total hardware failure, any workaround to resurect the net connection?

It was free, via the dumpster, so not a huge thing if it never works again, just kinda like to have all my toasters running with everything working.

Thanks in advance.

You probably need to replace the motherboard . I've seen it a few times on a couple off O2's I've bought . Have you tried to run diagnostics ? It usually fails on MACE controller if ethernet is bad
Nothing shows up wrong in either diagnostics or confidence tests. Very odd.
have you done a chkconfig? one of the things there will tell you if it's doing dhcp. I think ifconfig is another thing that may give you some clue too your ethernet's working condition.
dont worry about that last post, if your not getting a connect led on the router then the hardware is down.

check the board for obvious signs - bad soldering on the socket, damaged socket, burned network chip etch.

if you know what your doing you can get a datasheet for the network controller and probe the signals on it.
