Yes. I installed Sarge on a Laptop and sometimes the network goes down randomly. At
least, I can't figure out why.

This is exactly my error message. I think it can have several reasons. In my case it's the
firewire card (eth1) that takes over the network card (eth0), I don't know how this
happens. But in my case the fix is relatively easy. I do as root
ifconfig
Something like eth0 or eth1 should show up. If you have a Protocol:UNSPEC
something is wrong. You can try a combination of
ifconfig eth1 down (if this is the wrong card) and then
ifconfig eth0 up (if this is the right card).
Basically, you switch the card "off" with down and the other card "on" with up. Of course,
you choose the appropriate device name for your computer, but eth1 or eth0 should do
and you can try to switch your card on and off.
Even if this doesn't help you should post the result of ifconfig so that others might help
you.
