Further more i use this card in a bridged setup with a wired ethernet device. In this brigde the eternet device works ok. But on the wlan interface no broadcast or multicast seems to leave the interface. Clients attached to the AP seems to work fine. But when i for example try to reach any client from the ap the ARP does not get through to the client and im unable to connect to it until i first initiate some traffic from the client to the AP thus populating the ARP table the other way. Further more no multicast traffic seems to leave the AP such as fx mdns traffic. The AP it self on the other hand has no trouble receiving the same. Not sure if it gives any clue but running tcpdump on the AP tells me that the packets are "visible" on both the wlan0 and the br0 interface but the client does not pick them up, if they are sent. I thought that the "ath9k: Fix FIF_BCN_PRBRESP_PROMISC handling" in 2.6.29.3 should fix it but when reading https://bugzilla.redhat.com/show_bug.cgi?id=498502 i get the impression that this fix is for the problem the other way around, that the driver was unable to receive multi/broadcast. Cut down hostapd conf. Left out vme and logging config: interface=wlan0 bridge=br0 driver=nl80211 ssid=ap-test country_code=SE hw_mode=g channel=6 beacon_int=100 dtim_period=2 max_num_sta=255 rts_threshold=2347 fragm_threshold=2346 macaddr_acl=0 auth_algs=3 ignore_broadcast_ssid=0 ieee80211n=0 eapol_key_index_workaround=0 eap_server=0 own_ip_addr=127.0.0.1 wpa=3 wpa_passphrase=leftout wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP CCMP Anyone have any idea on where to dig further? Or is this a known issue? Best Regards, /Tor
