Description Andrew Walker 2011-01-26 23:50:20 UTC
D-Link DWA-556 wireless adaptor using ath9k in-kernel driver works perfectly in 'master' mode as wireless gateway using it's own subnet but as soon as it is used in bridged br0 networking it no longer functions in 'master' mode.
May be related to bug 288170 as bridge is created without error but wlan0 not added to it.
baselayout-1.12.14-r1
hostapd-0.7.3
gentoo-sources-2.6.36-r5

Reproducible: Always

Steps to Reproduce:
1.Reconfigure wlan0 and eth1 as bridge br0
2.Restart networking
3.

Actual Results:  
Bridge br0 created listing eth1 but not wlan0
Wireless no longer accessible from external devices

Expected Results:  
Should had created br0 with wlan0 and eth1 joined on same subnet

I'm no expert and I'm not 100% I've set my wlan0 correctly but I was following this howto
http://en.gentoo-wiki.com/wiki/Atheros_Ath5k_Wireless_Access_Point
and my card does function perfectly in un-bridged networking. I'm not sure if 
modules_wlan0=( "!iwconfig" "!wpa_supplicant" ) is neccessary or not in /etc/conf.d/net but it seems to get ignored in bridged and try to connect itself.

What is the latest kernel that used to work?

I've not tried it on earlier kernels as I think the driver is only available in recent kernels and all the advice I've read says it needs greater than 2.6.33 to work in 'master'

Please test with gentoo-sources-2.6.38, and let us know the outcome
