It copes fine on my LAN, which is 192.168.1.xx. So it's not a nonzero
3rd octet; that works fine.

Do you have DHCP?

GNOME Network Manager (the thing in the panel) is a userspace program.
It doesn't need root privileges.

I would not expect that to work. Did you keep backups of any files you
replaced? Can you revert this change?

What does `sudo -i` do? I've never needed it.

As I said, it's a userspace tool. It doesn't need sudo access, but if
you have hardwired stuff into place using config files from 4 versions
back, then you might well have broken it so that it /cannot/ now work.

Does for me. I use it all the time. Are you saying that even the
LiveDVD could not access the network? This is a key question.

You'll only break it further, I think.
