But someone cannot access internet. It not stable, I notice Ubuntu use very high CPU resource 95%!
The problem from NetworkManager bug.
So I try to stop the service by
sudo /etc/dbus-1/event.d/26NetworkManagerDispatcher stopand modify (insert) 'exit' in
sudo /etc/dbus-1/event.d/25NetworkManager stop
/etc/default/NetworkManageror remove this program by sudo aptitude remove network-manager
I have not use Ubuntu 8.10 yet. But I hope the problem will solove in the release.
