Description Hernan G Solari 2009-12-03 12:33:36 UTC
I believe this BUG me be the same or related to bug 13943. At least has several features in common. The wifi is working fine with madwifi-hal-0.10.5.6-current. And works with ath5k but I hit this warning some times (see below) and have to retry the connection in such cases. 02:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01) Subsystem: AMBIT Microsystem Corp.

This last too are in agreement as we know. Bug reported. Regresion.

The network is open (insecure). Happens only at the first attempt to connect. The second attempt is succesful. Using as network manager wicd. Connections made directly with iwconfig and dhclient3 do not trigger the bug.
Comment 1 John W. Linville 2010-03-01 18:58:07 UTC
Are you still seeing this with 2.6.33?
Comment 2 Hernan G Solari 2010-03-05 17:39:20 UTC
The problem is still there in 2.6.33. There is no much information in dmesg output now. But the behaviour is the same. I am attaching dmesg output (relevant part), iwlist scanning of node and iwconfig
Comment 3 Hernan G Solari 2010-03-05 17:42:23 UTC
Created attachment 25369 [details] iwlist iwconfig and dmsg output when connected
Comment 4 John W. Linville 2010-08-13 16:12:26 UTC
The warning has been removed, so I'm going to optimistically close this one. :-)
