If people are running into problems like this on Ubuntu, the best thing
to do to help debug the issue is to either file a bug report in
Launchpad, or grab your /var/log/NetworkManager.log file, or if that
doesn't exist /var/log/daemon.log and send it to this list so that we
can try to figure out what's going on.

Especially int he case of PPPoE/DSL, to debug further you can:

1) stop NetworkManager
2) as root, run NetworkManager like this:

NM_PPP_DEBUG=1 /usr/sbin/NetworkManager --no-daemon

3) try to reproduce the issue
4) send the NetworkManager debug output to this list
