I believe, that the bot does not try to log into the WiFi once it was kicked out (connection lost) and power cycled again.
Could you please change that, such that the bot always tries (for some times) to connect to the last known WiFi after power off / on cylce?
The bot does attempt to connect to the last used WiFi network after power cycles and reboots. It will only not attempt this if you factory reset the device.
