Follow these steps to check and refine the WiFi connection:

1. Ensure that the WiFi account and password are entered correctly.

2. Remove any special characters, spaces, or symbols (e.g. #, $, %, &, *) from the WiFi name or password.

3. Note that the device does not support 5G WiFi. If you are using a 5G network, switch to a 2.4G WiFi network.

4. If the previous attempts fail, you can try resetting the device. Refer to this guide for instructions: [https://www.youtube.com/watch?v=nLCp___nduY]. After resetting, reconnect the device to your WiFi.

5. If all the previous attempts fail, try connecting using a mobile hotspot. Please note that the device does not support 5G hotspots. If you can successfully connect using a mobile hotspot, it indicates that the brand/model of your router (WiFi) may not be compatible with this device.



Note: During the initial WiFi connection, the app will automatically initiate a mandatory upgrade for your device, which typically takes 2-3 minutes. Once the upgrade is complete, you can connect your device to the WiFi network.
