Disconnects from wifi
Kindle Fire automatically turn off Wifi after the device is idle for certain period of time. So When Funamo tries to sync the data each night, it will try to turn on the wifi, do the sync and then turn the wifi off. Normally, wifi should automatically reconnect once the device comes out of idle state. If your device does not do it for some reason, you can try to install an app called Wifi connection manager.
So your son can turn on/off wifi without opening Settings.
