I've noticed that "power management" is now ON with this new build. I tried to disable it, got a bad message:
root@overo:~# iwconfig wlan0 power off
Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan0 ; Operation not supported.

Crap.

This appeared to have worked at first, because the wifi stayed on for more than 2-3 minutes... but then this flashed on my console:
 
cfg80211: Calling CRDA for country: US

and then the blue wifi LED turned off. Still have IP, iwconfig says not connected to any access point.

any thoughts? the CRDA message is new to me.

Using the development image:
 Linux overo 3.0.0 #1 Tue Oct 11 11:37:21 PDT 2011 armv7l GNU/Linux

Thank you kishan. I'm currently using the stock image that came on the overo, built October 20 2010. I'll try a new image and see what it does. Thanks!

Are you using one of the pre-built development images (if yes, which one) or your own?

I had WiFi issues when I was using the factory pre-built development image. But when I used the latest development pre-built image, the WiFi worked fine.

After 2-3 minutes it turns off, and I have no network connectivity even though it think I do (with iwconfig, etc.). No dmesg statement, nothin'. I have to bring it down, bring it back up, and do the "iwconfig wlan0 essid on" to get it back up. Light comes back on and I'm good to go.
