I'm very happy to see this, I have been eagerly waiting for the official AP support in mac80211. I tried to test this with latest hostapd (commit b6a55236) and wireless-testing (commit d80fe0040), but unfortunately I wasn't succesful. Here's the output from hostapd with b43: $ sudo ./hostapd -dd wlan1.conf Configuration file: wlan1.conf ctrl_interface_group=0 Opening raw packet socket for ifindex 0 BSS count 1, BSSID mask ff:ff:ff:ff:ff:ff (0 bits) SIOCGIWRANGE: WE(compiled)=22 WE(source)=21 enc_capa=0xf Failed to update rate sets in kernel module 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 Could not set passive scanning: Unknown error 4294967295 Flushing old station entries Deauthenticate all stations Mode: IEEE 802.11g Channel: 5 Frequency: 2432 MHz Failed to set CTS protect in kernel driver Failed to set Short Slot Time option in kernel driver Could not set preamble for kernel driver Using interface wlan1 with hwaddr 00:11:50:f4:c2:42 and ssid 'test' ioctl[SIOCSIWESSID]: Operation not supported len=4 Could not set SSID for kernel driver wlan1: Unable to setup interface. Flushing old station entries Deauthenticate all stations With ath5k I had to add BIT(NL80211_IFTYPE_AP) to wiphy->interface_modes and the output is similar: $ sudo ./hostapd -dd wlan1.conf Configuration file: wlan1.conf ctrl_interface_group=0 Opening raw packet socket for ifindex 0 BSS count 1, BSSID mask ff:ff:ff:ff:ff:ff (0 bits) SIOCGIWRANGE: WE(compiled)=22 WE(source)=21 enc_capa=0xf Failed to update rate sets in kernel module 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 Could not set passive scanning: Unknown error 4294967295 Flushing old station entries Deauthenticate all stations Mode: IEEE 802.11g Channel: 5 Frequency: 2432 MHz Failed to set CTS protect in kernel driver Failed to set Short Slot Time option in kernel driver Could not set preamble for kernel driver Using interface wlan1 with hwaddr 00:0f:3d:a9:7d:82 and ssid 'test' ioctl[SIOCSIWESSID]: Operation not supported len=4 Could not set SSID for kernel driver wlan1: Unable to setup interface. Flushing old station entries Deauthenticate all stations rmdir[ctrl_interface]: No such file or directory Especially I'm worried about "SIOCSIWESSID: operation not supported" messages. I'm sure I'm just doing something wrong, but what? I tested this on Lenovo X60s laptop running debian unstable in 32 bit environment.
