I am not 100% sure what you mean with __default__ gateway.
I started in recovery mode and then I did  init 3, logged in an the network worked

seb at notebook:~$ ifconfig eth0
eth0      Link encap:Ethernet  HWaddr
           inet addr:192.168.0.2  Bcast:192.168.0.255  Mask:255.255.255.0...

ifconfig seems fine to me here.

I then restarted, normal, logged in and it worked again. Strange things are happening here ?:-\

ifconfig -a eth0
eth0      Link encap:Ethernet  HWaddr
           inet addr:192.168.0.2  Bcast:192.168.0.255  Mask:255.255.255.0

ifconfig shows the same result here.

Thanks very much for your help

Cheers, Sebastian
