This was the first thing that came to me when I was reading your
original e-mail, because I've had some serious issues with avahi on
Ubuntu on a laptop.  It is supposed to be some sort of zeroconf
program to setup networking on small networks with no real network
config (as I understand it, I only glanced at it briefly).  All it's
ever been to me was a huge pain in the ass.

The fact that the Ethernet link seems to be dropping makes me think
your specific issue here might not be related to avahi, but I would
strongly recommend killing it entirely and seeing if that helps any.
It was taking over the default route on my box and killing network
connectivity constantly until I removed it.
