Help w/ gumstix wifi interface =\

[Blaine]

I completely forgot... we built in a ping command to our application.
WITHOUT this ping command every 30 seconds we get disconnected from AP
every 2-3 minutes. Completely forgot about that. We turned on some debug
and it looks like we just get a DEAUTH (deauthentication) message.

Linux overo 2.6.34 #1 Wed Oct 20 10:22:48 PDT 2010 armv7l GNU/Linux

New builds do not help from what we can tell.
