Comment 7 for bug 50099

I have the same problem. I need to deactivate and reactivate eth0 from Gnome networking prefs. There is my /etc/network/interafces :

auto lo eth0
iface lo inet loopback

iface eth0 inet static
address 192.168.1.102
netmask 255.255.255.0
gateway 192.168.1.1
wireless-essid kothlis
