Comment 12 for bug 320268

well, unfortunately I don't even have the old kernel. I was using wireless and after deciding that the new kernel seems stable I removed the old one. then I went home, connected to my wired network and vola .... nothing. I can't get it to see my router or get any IP from eth0.
I searched around and tried all the different dhclient commands, starting/stopping interfaces ... nothing...I'm lucky my neighbour has an unsecure wireless lan :) or I could not use the machine.
The same happens at work where we have Cisco routers with DHCP, my netbook worked without problems there before, so we can assume that it's not something the router does but rather the network manager doesn't do or know.

I tried the "supersede nameserver" option as well and it changed nothing.
let's hope for another update that miraculously solves this just liked it got broken.
