Re: [Gumstix-users] Confirmed Working Image (2.6.34 desktop) for Overo Wifi

[Louis Saint-R. <lou...@ep...>]

Hi Blaine,
if you are still interested, I use the Kernel 2.6.39 from August 2011 
and wifi (WEP secure, static IP) works mainly well. I always have the 
wifi ready(wlan1) at the end of the boot, but the wifi disconnects after 
few minutes if I do not use it, like you, but it is not a big issue for me.

I did like this, inspiring me from 
http://gumstix.8.n6.nabble.com/WiFi-problems-td564654.html and maybe 
somewhere else:
remove NetworkManager, edit /etc/network/interfaces, add a script in 
/etc/init.d which will scan and ifdown/up

Let me know if you want all the details.

Louis
