I'm trying to use the channel
144 for wifi. I get the following error in the log file when I try to use it:
Sat Feb 25 21:50:38 2017 daemon.notice hostapd: Channel 144 (secondary) not allowed for AP mode Sat Feb 25 21:50:38 2017 daemon.warn hostapd: wlan0: IEEE 802.11 Configured channel (140) not found from the channel list of current mode (2) IEEE 802.11a Sat Feb 25 21:50:38 2017 daemon.warn hostapd: wlan0: IEEE 802.11 Hardware does not support configured channel Sat Feb 25 21:50:38 2017 daemon.err hostapd: Could not select hw_mode and channel. (-3)
iw list phy0 shows the following information for channel
* 5700 MHz  Maximum TX power: 27.0 dBm Radar detection Channel widths: 20MHz HT40- VHT80 VHT160 DFS state: usable (for 223 sec) DFS CAC time: 60000 ms
GB for the wireless device in
/etc/config/wireless. All other channels which show as available in
iw phy0 channels seem to work.
Any help is appreciated.
