All,

I'm having a hard time keeping a connection to a Ruckus ZoneFlex 7982 AP. 
The SSID is running WPA2/PSK/AES.  I'm running a recent iwlwifi kernel 
(3.12.0-rc3-wl+) and have a Centrino chipset.  After an hour or so, the 
interface is disconnected.  It can only reauthenticate when the iwlwifi 
module is removed and re-inserted.

Thanks in advance,
Ken

I'm running a recent wpa_supplicant with nl80211 like this:

/sbin/wpa_supplicant -Dnl80211 -s -i wlan0 -c ./gr-test.conf

The relevant log output is the following (I think):
