The PC is:

Target OS:
Ubuntu 7.10

Target WWW interface:
-- It is working fine with Vista OS via USB now.

The Ethernet connection works, but WWW connetivity is nil.
I suspect that DHCP configuration is the problem, not some deeper hardware
config problem.

When I go to
"Devices - Network Tools"
> "Ethernet Interface (eth0:avahi)" [Configure]

it says
"The interface does not exist"

I am able to get routing information from "Netstat" tab just fine.

It is my understanding that as this is a brand new computer that the BIOS is
fine, and that WWW connectivity probably worked at installation.
