Hello, I am running a hostapd with following setup: interface=wlan0 bridge=br0 driver=nl80211 hw_mode=g channel=5 ssid=xxx auth_algs=1 wnm_sleep_mode=1 beacon_prot=1 ieee80211w=1 wmm_enabled=1 #wmm_ac_* like in example ap_isolate=1 ieee80211n=1 ht_capab=[HT40-][GF][SHORT-GI-20][SHORT-GI-40] dynamic_vlan=1 per_sta_vif=1 wpa=2 wpa_psk_file=/etc/hostapd/hostapd.wpa_psk wpa_key_mgmt=WPA-PSK rsn_pairwise=CCMP In general it works. But I noticed that after two days multicast communication fails for all stations. (mdns discovery stops working.) At the time it fails I noticed in the hostapd log the rekey entries. The default is a rekey every 24h. So I changed it to 5 minutes to check: wpa_group_rekey=300 Now multicast failed after 10 minutes. (So the first rekey after 5 minutes worked, but the second and any further rekey succeed according to log, but multicast does not work.) (I could increase rekey interval or disable it all together, but I guess thats not recommended. ;) ) Deauthenticating the clients with "hostapd_cli deauthenticate" sometimes recovers multicast for up to 10 minutes. Not sure why it does not recover everytime. Hardware is a ALFA AWUS036ACHM with mediatek mt76. Kernel is 6.6.37, linux-firmware from July. Recently updated hostapd to latest git version. All stations are affected, at the moment android devices and various smart home devices from different brands. Any idea what the problem could be? Is it a misconfiguration or some bug? Any help is highly appreciated. Thank you, Markus _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
