Using the Gumstix Angstrom Factory image as available at http://cumulus.gumstix.org/images/angstrom/factory/2011-08-30-1058/, I have run a problem with the WIFI not being able to connect to any type of access point (unencrypted or WPA2). 

I am able to scan the local environment and indeed find available access points with high signal. 

I have removed the network manager and followed instructions at http://wiki.gumstix.org/index.php?title=Overo_Wifi to the tee without success. I have noticed a large amount of problems with the wifi dating from 2010 to 2012 from the mailing list. 

Questions:
1. Has there been resolution on this issue? How can we use the wifi in managed mode via WPA2? 
2. How can we use the WIFI hardware in access point mode!?
