Ok, here's the latest.

Did a fresh install and did th emods described here with rndis-lite. It appears to be getting an IP address as shown in var/log/syslog:

Aug 22 08:59:26 eeepc avahi-autoipd(rndis0)[11330]: Found user 'avahi-autoipd' (UID 104) and group 'avahi-autoipd' (GID 110).

However, as you can see, if the system tries to go anywhere, it can't.

I note my MTU is very high, MTU 3954. Could this be a problem?

Thanks again.
