Re: [Gumstix-users] Overo Wifi is "turned off" after 2-3 minutes of inactivity.

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.
