Turn flight mode on and off
Usually, when having network issues, it is a common practice to restart your device.
But there is an easier alternative to get the same result: activate the Airplane mode from the notification bar and, after a few seconds, turn it off again.
This procedure will disable all the wireless transmission functions, such as the mobile network, the Wi-Fi or the Bluetooth, and then start them back again, without having to go through a full reboot.
Reset the network settings
When you can’t connect to a Wi-Fi network or you experience other network issues, it is recommended to reset the network settings.
This will erase all your saved Wi-Fi networks and their passwords and will bring the network settings back to their original state.
After the reset, you will be able to set up all your mobile and Wi-Fi networks and clear out any potential issues.
