I have an intel 5300 as client and openwrt ath9k based router as AP. Some times (once in several days) I get wireless connection spontaneously dropped with this message on client: wlan1: deauthenticating from XX:XX:XX:XX:XX:XX by local choice (reason=3)

Ubuntu 11.10 on a Thinkpad X200 with Intel 5300:

$ dmesg | grep -i deauthenticating | grep "local choice" | wc -l
44
$ uptime
 18:31:07 up 1 day,  7:30,  3 users,  load average: 0.08, 0.03, 0.05

$ dmesg | grep "local choice" | cut -d ] -f2- | sort | uniq -c
     44  wlan0: deauthenticating from 00:21:91:dc:94:55 by local choice (reason=3)
     56  wlan0: disassociating from 00:21:91:dc:94:55 by local choice (reason=3)

 Not that this really creates problems for me, connection is quickly
restored and otherwise works fine.

For me it also mostly works fine, but sometimes I have to unload/reload the iwlagn module to make things work again, and sometimes the wifi LED just turns off and requires a reboot to get working again.

At least the 5300 stuff works much better in 3.0 than it did in 2.6.38.
