[ubuntu-uk] Lost networking during 8.04 to 8.1 upgrade

I have posted this on the Ubuntu support forums, but to see if I speed
up getting help, I have also posted it here.  This is a Thikpad T42,
and was working fine before the upgrade and although I allowed
Synaptic to manage the upgrade, I have, since it broke, booted from an
8.1 live CD and the networking is fine with the live CD.

When rebooting the network manager icon spins for a while and then
tells me the network is disconnected and that I am now offline. I have
tried rebooting a couple of times after the upgrade but this doesn't
help

Same problem occurs whether I try to connect to the wireless or wired networks.

This is only an interim upgrade on my way to jaunty, but I assume I
need to get 8.1 working properly before upgrading. In any case I,
ideally need, to get my network back up and runnning to download
Jaunty.

Below are the print outs from lshw -C network and ifconfig and
/etc/network/interfaces only has this in it:

auto lo
iface lo inet loopback


any suggestion gratefully recieved.

Thanks,

Graham
