Thanks for your mail, but very pity, after checking, it doesn't as well. May you test it on your board? # iw reg get country US: (2402 - 2472 @ 40), (30, 0) (5170 - 5250 @ 80), (17, 0) (5250 - 5330 @ 80), (23, 0) (5735 - 5835 @ 80), (30, 0) (57240 - 63720 @ 2160), (40, 0) country_code=US hw_mode=a channel=149 #hostapd -B /etc/hostapd.conf Configuration file: /etc/hostapd.conf channel [19] (149) is disabled for use in AP mode, flags: 0x7 wlan0: IEEE 802.11 Configured channel (149) not found from the channel list of current mode (2) IEEE 802.11a wlan0: IEEE 802.11 Hardware does not support configured channel Could not select hw_mode and channel.

Please use a non-DFS channel like 36/40/149 and then try (or) change the country_code which has 104 allowed :-). You can also use "iw reg get" to get list of bands allowed, all the bands marked with passive-scan are not allowed in AP mode unless we implement full DFS functionality (CAC) and make the channel usable. Also use a separate thread, dont post in other threads. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
