Do NOT drop the mailing list. ALWAYS Reply All. I do not do private debugging 
unless you are paying!

The dmesg fragment showed no reason for a failure to even try to connect. On my 
system, I get

It looks exactly like your output through the "link is not ready" message. At 
that point, NetworkManager starts the authentication process.

What do you see in the NM log file? It should be at /var/log/NetworkManager?

I would also like to see the output of the 'iwlist scan' command when run as root.
