Wi-Fi keeps disconnecting/not connected: There may be many reasons why your phone doesn’t connect to Wi-Fi or the connection keeps dropping. Sometimes the Wi-Fi problem is related to the Bluetooth. If your Bluetooth is on try toggling the icon putting it off might work better.

  • Ensure that the Power Saving option is turned off – you can find the option by going to Settings > Battery.

Not Registered On Network
