I sent a patch to disable power save by default, but then work started
to fix it instead, but then stalled. Seems like 2.6.38 shipped with
broken power save enabled by default. Plese read the discussion
following my RFC patch:
http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2011-January/thread.html#3017
You can test if power saving causes your issue by disabling
it with "iwconfig wlan0 power off".
