How to troubleshoot if Wi-Fi device fails to connect successfully?
If the Wi-Fi device fails to connect successfully, you can troubleshoot by following these steps:
  1. Before starting the connection process, carefully read the product manual to ensure that the app you are using matches the recommended app in the manual.
  2. Ensure that the device is powered on and in the correct setup mode.
  3. Confirm that the device is using the 2.4GHz network frequency for connection and verify the accuracy of the Wi-Fi password.
  4. To rule out router issues, try using another smartphone to create a Wi-Fi hotspot (iPhone users should enable maximum compatibility) for the connection attempt. If the connection is successful, check the router settings; if it still fails, it may involve hardware faults or operational issues, and you should consult the seller.
