Troubleshooting Steps:

1. Check if the Wi-Fi hub light is functioning normally. When not in network configuration mode, the light should be flashing red; after successful configuration, the indicator should be flashing green.
2. Check the model of the user’s home router, the internet service provider, and other information to ensure that the home network is functioning correctly and that there are no overdue payments causing a disconnection.
3. If the Wi-Fi hub light is not on, try replacing the power supply or power cable to see if the light functions normally.
4. If the Wi-Fi hub light is functioning normally, press the doorbell button to test and observe whether the Wi-Fi hub produces a doorbell sound. If there is no sound, it indicates that communication between the Wi-Fi hub and the lock has been interrupted, and you will need to re-pair the Wi-Fi hub with the lock.

5. The process to re-pair the Wi-Fi hub with the lock:
5.1. Restore the Wi-Fi hub to factory settings (press and hold the reset button for about 10 seconds until the Wi-Fi hub’s purple light turns on, indicating a successful reset; after the reset, the red light on the Wi-Fi hub will flash).
5.2. Pair the lock with the Wi-Fi hub by pressing the program button on the back panel of the lock to enter pairing mode, and click the PR button on the screen.
5.3. Press the PR button on the display. Be sure to wait for the lock to beep twice (“beep beep”) before pressing the reset button on the Wi-Fi hub three times in quick succession. At this point, wait for the lock to emit a long beep, indicating that the Wi-Fi hub and lock have been successfully paired. If you do not hear this sound, it means the pairing was unsuccessful, and you need to repeat this action until pairing is successful.
5.4. After successful pairing, follow the lock binding process in the app step by step until the binding is successful.

6. If a connection timeout occurs during the binding process, try moving the Wi-Fi hub as close to the lock as possible. Place the Wi-Fi hub on a flat surface, ensuring that the connected WiFi is 2.4G, not 5G. The router settings must separate the 2.4G and 5G signals and cannot be set to a dual-band mode. If it still does not work, switch the phone’s network to a 4G signal or switch from the original 4G signal network to the same WiFi network and try again.

Additionally, you can use a mobile 4G hotspot for connection testing to check if it works. If the mobile hotspot can connect, it indicates that there is an issue with the home WiFi network, which is unrelated to the product, and further investigation of the home WiFi network is needed.
