Network problem (kubuntu 8.10)

[Emanoil Kotsev]

This is a silly network management issue I had too

the answer is that the kde network manager is not working if you have something set in /etc/network/interfaces

you hsould have tehre only 

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0


try this I hope it works for you
