Hello, I ran into problems configuring multiple BSSID in hostapd, because hostapd is running in an error. My intention is to set up one public ssid and one private ssid. I think it is a configuration problem, but neither Google nor http://linuxwireless.org/ gives a hint. I did following steps: debian:~# iw reg set DE debian:~# ip link set wlan0 addr 00:15:6d:84:0e:00 ...works so far config file /etc/hostapd/hostapd.conf contains following content: interface=wlan0 bridge=br0 driver=nl80211 ieee80211n=1 ht_capab=[SHORT-GI-40][DSSS_CCK-40][HT40-][HT40+][HT20] ctrl_interface=/var/run/hostapd ctrl_interface_group=0 ssid=cftest country_code=DE ieee80211d=1 hw_mode=g channel=1 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 wme_enabled=1 wme_ac_bk_cwmin=4 wme_ac_bk_cwmax=10 wme_ac_bk_aifs=7 wme_ac_bk_txop_limit=0 wme_ac_bk_acm=0 wme_ac_be_aifs=3 wme_ac_be_cwmin=4 wme_ac_be_cwmax=10 wme_ac_be_txop_limit=0 wme_ac_be_acm=0 wme_ac_vi_aifs=2 wme_ac_vi_cwmin=3 wme_ac_vi_cwmax=4 wme_ac_vi_txop_limit=94 wme_ac_vi_acm=0 wme_ac_vo_aifs=2 wme_ac_vo_cwmin=2 wme_ac_vo_cwmax=3 wme_ac_vo_txop_limit=47 wme_ac_vo_acm=0 eapol_key_index_workaround=0 eap_server=0 own_ip_addr=127.0.0.1 bss=wlan0_0 ssid=taunusstein.net after starting hostapd with that config following happens: debian:~# hostapd -ddd /etc/hostapd/hostapd.conf Configuration file: /etc/hostapd/hostapd.conf ctrl_interface_group=0 Opening raw packet socket for ifindex 166465272 BSS count 2, BSSID mask ff:ff:ff:ff:ff:fe (1 bits) SIOCGIWRANGE: WE(compiled)=22 WE(source)=21 enc_capa=0xf nl80211: Added 802.11b mode based on 802.11g information Allowed channel: mode=1 chan=1 freq=2412 MHz max_tx_power=20 dBm Allowed channel: mode=1 chan=2 freq=2417 MHz max_tx_power=20 dBm Allowed channel: mode=1 chan=3 freq=2422 MHz max_tx_power=20 dBm Allowed channel: mode=1 chan=4 freq=2427 MHz max_tx_power=20 dBm Allowed channel: mode=1 chan=5 freq=2432 MHz max_tx_power=20 dBm Allowed channel: mode=1 chan=6 freq=2437 MHz max_tx_power=20 dBm Allowed channel: mode=1 chan=7 freq=2442 MHz max_tx_power=20 dBm Allowed channel: mode=1 chan=8 freq=2447 MHz max_tx_power=20 dBm Allowed channel: mode=1 chan=9 freq=2452 MHz max_tx_power=20 dBm Allowed channel: mode=1 chan=10 freq=2457 MHz max_tx_power=20 dBm Allowed channel: mode=1 chan=11 freq=2462 MHz max_tx_power=20 dBm Allowed channel: mode=0 chan=1 freq=2412 MHz max_tx_power=20 dBm Allowed channel: mode=0 chan=2 freq=2417 MHz max_tx_power=20 dBm Allowed channel: mode=0 chan=3 freq=2422 MHz max_tx_power=20 dBm Allowed channel: mode=0 chan=4 freq=2427 MHz max_tx_power=20 dBm Allowed channel: mode=0 chan=5 freq=2432 MHz max_tx_power=20 dBm Allowed channel: mode=0 chan=6 freq=2437 MHz max_tx_power=20 dBm Allowed channel: mode=0 chan=7 freq=2442 MHz max_tx_power=20 dBm Allowed channel: mode=0 chan=8 freq=2447 MHz max_tx_power=20 dBm Allowed channel: mode=0 chan=9 freq=2452 MHz max_tx_power=20 dBm Allowed channel: mode=0 chan=10 freq=2457 MHz max_tx_power=20 dBm Allowed channel: mode=0 chan=11 freq=2462 MHz max_tx_power=20 dBm HT40: control channel: 1 secondary channel: 5 RATE[0] rate=10 flags=0x2 RATE[1] rate=20 flags=0x6 RATE[2] rate=55 flags=0x6 RATE[3] rate=110 flags=0x6 RATE[4] rate=60 flags=0x0 RATE[5] rate=90 flags=0x0 RATE[6] rate=120 flags=0x0 RATE[7] rate=180 flags=0x0 RATE[8] rate=240 flags=0x0 RATE[9] rate=360 flags=0x0 RATE[10] rate=480 flags=0x0 RATE[11] rate=540 flags=0x0 Passive scanning not supported Flushing old station entries Deauthenticate all stations Mode: IEEE 802.11g Channel: 1 Frequency: 2412 MHz Using interface wlan0 with hwaddr 00:15:6d:84:0e:00 and ssid 'cftest' Failed to add BSS (BSSID=00:15:6d:84:0e:01) wlan0: Unable to setup interface.

My platform: * Alix 2D3 * Ubiquity SR-71A (driver ath9k from compat-wireless-2009-07-31) * Debian Lenny * Kernel 2.6.30.4 * compat-wireless-2009-07-31 * 2009.04.17-regulatory.bin * crda-1.1.0 * hostapd-0.6.9 * iw-0.9.15 As long as no additional bss is configured, everything works well including WPA/WPA2 and 802.11n but channels 12/13 - but at this time I don't care about that missing channels.
