Hi everyone. I'll keep it quick. Unlike most overo issues, when my wifi is working it works fine (I think). I can ping google and for now that's all that matters.
I can see the little blue LED on my board. When I connect to an access point successfully, it flashes and then stays on. 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.
If I hold a ping command like "ping google.com
" there are no problems and it will stay on continuously until 2-3 minutes after stopping the ping.
I remember that the LCD display has a power saving mode that we never figured out how to disable. Is this related? All I want is stable wifi that doesn't turn off. I can't figure out what is causing this behavior. Suggestions are greatly appreciated.
