There are times you are unable to connect to your WiFi router. This can be especially problematic when you have increasing number of WiFi dependent IoT devices. Many times, the remedy is to simply reboot the router i.e. unplug the power cord, wait for a few seconds and plug it back again.
If you do not want to go through that trouble on the ongoing basis, this apparatus will keep an eye on the wifi connectivity. If the connectivity goes down, it will turn on the buzzer to give warning to the user, then it will turn the router off for a predefined time using a relay. Will turn the router on again. After the router turns on, it will wait for a while to perform check on the WiFi.
