Steps to reproduce
It can be after a few hours, if WiFi 5g radio0 Qualcomm Atheros QCA9880 802.11nac (radio0) is configured to a Band B channel, it jumps to Channel 36 even though there is no apparent interference.
This appears to happen more frequently overnight during long periods of inactivity. Whilst the device is being used it does not happen.
After it does make the jump, if I stop and restart the device (using luci disable/enable) the device stops, but it fails to restart. Attempts to change the channel and re-enable the device also do not help.
It requires a reboot to restore service.
