I have my modem/wifi plugged to the KP303 power bar and set it to reboot over night daily. It looks like the modem is rebooted in the morning but the power bar would not reconnect to the wifi (shows powered off in Kasa app and the green light is blinking which means it's trying to find the network). 

However, my other wifi devices could all re-connect automatically. 

How can KP303 re-connect to wifi properly?

I tried to look for new firmware in Kasa but it is up-to-date.
