Please try the below:
1. Stay close to the router to avoid automatic disconnection due to weak signal.
2. If many devices are connected to the same WiFi network, disconnect them.
3. If you're using a metal protective case, remove it and try again.
4. Turn the WiFi off and on to check again.
5. Try using another WiFi network.
If the issue persists, please contact our Customer Support for further assistance.
