Best thing to do is to file a bug in Red Hat bugzilla and then we can
diagnose this issue further.  If you could put some more details into
the bug report, like:

1) What kernel version, what wireless card, and what driver the card is
using

2) Attach a /var/log/messages that shows a NetworkManager connection
attempt to the bug report

#2 is important; without that it's hard to figure out where things are
going wrong.

Thanks,
