No HT features enabled. I believe there is at least one station running powersave, because I got this message from hostapd: wlan1: STA 90:4c:e5:b7:d2:cb IEEE 802.11: authenticated wlan1: STA 90:4c:e5:b7:d2:cb IEEE 802.11: associated (aid 2) wlan1: STA 90:4c:e5:b7:d2:cb RADIUS: starting accounting session 4D39A118-00000001 wlan1: STA 90:4c:e5:b7:d2:cb WPA: pairwise key handshake completed (WPA) wlan1: STA 90:4c:e5:b7:d2:cb IEEE 802.11: deauthenticated due to local deauth request Data/PS-poll frame from not associated STA 90:4c:e5:b7:d2:cb Data/PS-poll frame from not associated STA 90:4c:e5:b7:d2:cb The wireless interface is running bridged with a VLAN ethernet interface. Traffic is mostly ssh and some http and it's bellow 500 kbps We have another AP (Cisco) running with the same SSID on a different channel and stations hop between them both without problems. Since this is our office, I immediately switched of the hostap when I got this message to avoid disrupting my colleagues work. But I can repeat the test on Monday if you like. hostapd config bellow: ctrl_interface=/var/run/hostapd ctrl_interface_group=wheel macaddr_acl=0 auth_algs=3 ignore_broadcast_ssid=0 wpa=1 wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP CCMP wpa_passphrase=XXXXXXXXXX driver=nl80211 interface=wlan1 hw_mode=g channel=11 ssid=ISP_Outsourcers bridge=br0 Regards, Jorge -------------- next part -------------- A non-text attachment was scrubbed...
