Hello, I'm attempting to configure two (and I hope eventually four) SSID's on my Atheros AR2425-based card, but am getting an error. Some system details first, then the output (and error) I'm getting from hostapd: # uname -a Linux demo-01 3.2.0-0.bpo.4-686-pae #1 SMP Debian 3.2.32-1~bpo60+1 i686 GNU/Linux # dmesg |grep "ath5.*chip" [ 3.076088] ath5k phy0: Atheros AR2425 chip found (MAC: 0xe2, PHY: 0x70) # hostapd -v hostapd v0.6.10 # cat /etc/hostapd/hostapd.conf interface=wlan0 driver=nl80211 ssid=demo1 channel=1 hw_mode=g auth_algs=1 bss=wlan0_0 ssid=demo2 # hostapd -dd /etc/hostapd/hostapd.conf Configuration file: /etc/hostapd/hostapd.conf Opening raw packet socket for ifindex -1216462906 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 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 Mode: IEEE 802.11g Channel: 1 Frequency: 2412 MHz Flushing old station entries Deauthenticate all stations Using interface wlan0 with hwaddr 00:25:56:22:bf:04 and ssid 'demo1' Could not set DTIM period for kernel driver Failed to add BSS (BSSID=00:25:56:22:bf:05) wlan0: Unable to setup interface. Failed to remove interface. That "Failed to add BSS" bit is where I'm stumped. I've seen several people on mailing lists discussing the MAC address mask, and while I haven't found an explanation of that idea that I fully understand, it seems relevant so I've tried a few variations on my configuration following their lead. My card's actual MAC address is 00:25:56:22:bf:04, but I've tried changing my card's MAC address using the following commands: ifconfig wlan0 down ifconfig wlan0 hw ether 02:25:56:22:bf:04 ifconfig wlan0 up I tried that particular address since one person said the first two digits being "02" would make it locally-administered, which they seemed to think was desireable. I also tried: 00:25:56:22:bf:00 (since another said the last digit should be 0) 02:25:56:22:bf:00 (trying both of those ideas at once) I tried each of those MAC addresses both with and without a "bssid=" line appended to hostapd.conf followed by a wide array of likely-seeming, neighboring MAC addresses (the last digit incremented or decremented by 1 or more). Every time though, I get that error message. Does anyone have an idea of what I might be doing wrong? I'm at the end of my rope!
