lo, the loopback interface, is (close your eyes now if you don't want
the geek explanation) what client/server protocols on the same system
use to speak to each other. Loopback is not your problem, and I'd be
worried if it *wasn't* working.

I suspect the problem may be with routing. You can type "route" at the
command line (or use the gnome-network-tools item from your System menu,
I think) to see which interface is used to send information out. On my
computer it says
[EMAIL PROTECTED]: ~] route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.11.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0
0.0.0.0 192.168.11.1 0.0.0.0 UG 0 0 0 wlan0
which means that, to reach the outside world, packets must be sent to my
wireless interface wlan0. If your default (0.0.0.0) interface is eth0,
as I suspect, then packets are being spewed out of your ethernet
interface and thus not making it to the internet.
If you're feeling intrepid, you could fix routing problems by following
the instructions on the man page for route - some command like "route
add default ppp0" - without editing or restarting anything.
You can fix it by disabling eth0 (either using the network configuration
tool from the menu or by editing /etc/network/interfaces) and then
restarting your network ("sudo /etc/init.d/network restart" or however
you do things - perhaps just restart).
I may be wrong, but let us know what route says, and for good measure
also what "arp -n" outputs. The gurus on this list might be able to
tell you how to configure routing the right way.
