Wi-Fi Connection Failure

Applicable Products: B221, B220, POE Doorbell, Battery Doorbell

Wi-Fi connection failures for wireless cameras are typically caused by signal interference, configuration errors, or hardware issues. This guide provides a systematic troubleshooting plan to help you locate and resolve the problem quickly.

I. Solutions for Initial Configuration Failure

1. Confirm Wi-Fi Band Compatibility The B221 and B220 models support 2.4GHz only (not compatible with 5GHz). Please check your router management interface to:

• Ensure the 2.4GHz network is enabled.
• If your router has "Smart Connect" (Dual-band Steering) enabled, it is recommended to temporarily disable it. Ensure both your smartphone and the camera are connected to a dedicated 2.4GHz signal during setup.

2. Password Verification and Optimization

• Wi-Fi passwords are case-sensitive. Use the "Show Password" icon to verify your entry.
• To improve connection stability, keep your SSID (network name) and password simple (letters and numbers). Avoid using special characters like %, &, or #.

II. Troubleshooting Frequent Disconnections

1. Check Device Status Confirm the power adapter is functioning. Observe the indicator light to determine the device status:

• Solid Blue: Online and working correctly.
• Flashing Red/Blue: Needs reconfiguration or indicates a device abnormality.

2. Network Environment Diagnosis

• Internet Connectivity: Verify the router can access the internet by testing other devices.   
• Configuration Changes: If you recently changed your Wi-Fi name or password, the camera must be reconfigured.
• Router Security Settings: Ensure MAC address filtering or parental controls are not blocking the camera. If necessary, add the camera’s MAC address to the "Allowed" list.

3. Wireless Signal Optimization

• Signal Strength Test: Temporarily move the camera closer to the router to rule out signal attenuation caused by walls or distance.
• Channel Interference: Log in to your router and manually set the 2.4GHz channel to 1, 6, or 11 (avoid "Auto" mode) to reduce interference from microwaves or Bluetooth devices.

III. Advanced Troubleshooting

If the steps above do not work, try the following:

1. Reset and Restart

• Regular Restart: Power cycle both the camera and the router to clear network cache.
• Factory Reset: Press and hold the Reset button on the device for 3–8 seconds. Reconfigure the network after the reset. (Note: Back up important recordings before resetting).
• Router Reset: If other devices are also struggling, consider resetting your router to factory defaults to clear configuration errors.

2. System and Network Adjustments

• Firmware Update: Visit the manufacturer's website to download the latest firmware. This often fixes compatibility bugs. (Ensure the device is fully charged before updating).
• IP Conflict Check: Check the DHCP client list in your router. If the camera’s IP conflicts with another device, assign a Static IP to the camera.

3. Network Isolation Test (Hotspot Test) Set up a mobile hotspot on a smartphone with the same SSID and password as your 2.4GHz router network. Attempt to connect the camera to the hotspot. If it connects successfully, the issue lies within your router’s settings.
