What should I do if Video Doorbell S4(T8215) cannot connect to the router?
Troubleshooting steps: 1. Check the power supply: ensure the device is connected to AC power, and press the doorbell button to see if the light turns on, which confirms a proper AC power connection. 2. Check the Wi-Fi password: confirm the Wi-Fi password is entered correctly. 3. Adjust the positioning: keep the device close to the router and avoid metal wall obstructions.
