Have RPi3b on 2.4gzh. Never had any issues.
But recently it was un-responsive, did not do its tasks, and unable to SSH to check - but still AX88U reported it as connected on wifi.
Settings on 2.4ghz is WPA2, 20/40mhz, with auto-channel, (no auto for ch 12,13) and the router had selected ch 9 (in yellow).
Changed the channel to manually ch1, the RPi3b now respond on SSH - and works as it should again.
This happend after update to 386.2_4. Some firewall/port problems in AX88U which blocks sometimes?
