WiFi Checker

This app will access the network on a regular basis and notify you if communication fails.

When the scheduled operation is started, it pings the default gateway periodically (every 15 minutes by default, or at irregular intervals depending on the power saving function of the OS) to check the response. Notifies you if the connection fails 3 times. Check communication even if the screen is off. However, it is not checked when Wi-Fi is off.
