NM prints information to /var/log/messages about what's going on with
the network.  If you could pastebin the section of
your /var/log/messages that shows a connection attempt or two, we can
diagnose further.  Based on the /var/log/messages I may ask that we move
this to bugzilla.

More info on debugging NM can be found here:
