Hello Trung, apologies for not getting back to you earlier.
The Overo does not support AP mode due to the wireless driver limitation.
People have tried Libertas ThinFirm with success however. Details can be

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. 

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!?
