Can you confirm that the proper mac address shows up if you do ifconfig
or macchanger -s?  I think it's just not associating.  

Also can you try specifying the ap again to trigger a probe after 
ifconfig up:

    $ iwconfig wlan0 ap <your AP's mac address>

Though I did forget about this gem, try this too:
