'unavailable' could mean a couple things:

1) supplicant isn't running or can't be contacted via D-Bus
2) rfkill is blocking wifi
3) the driver returned ENOENT in response to the dev_open() call,
indicating that it does not have any firmware available

The logs you've posted don't look complete; do you get *anything* else
shown?  You can also:

killall -TERM NetworkManager
NetworkManager --no-daemon --log-level=debug

to get more information.

Let me know,
