4.2 Power over Ethernet (PoE) Connection
- Connect one end of the Ethernet cable to the PoE IN/WAN port on the AP820 unit. Ensure the weather-sealed cap is properly installed around the cable.
- Connect the other end of the Ethernet cable to the PoE port on the PoE converter.
- Plug the power adapter into the PoE converter and then into a power outlet.
4.3 Initial Configuration (Web Interface)
- Connect your computer directly to the LAN port of the PoE converter using an Ethernet cable.
- Open a web browser and enter the default IP address (e.g., 192.168.188.253) or the domain name (e.g., wifi.wavlink.com) provided in the quick start guide to access the web management interface.
- Follow the on-screen instructions to configure the device's operating mode (AP, Gateway, or Repeater), Wi-Fi settings (SSID, password), and other network parameters.
4.4 Mounting the Device
The AP820 can be mounted on a wall or pole using the provided installation package. Ensure the device is installed in a location that is not higher than 2-3 meters (6.562 to 9.843 feet) from the ground and not higher than the upstream router or subordinate devices by the same height range.

6. Maintenance
- Regularly check the device for any physical damage or loose connections, especially after severe weather conditions.
- Ensure the weather-sealed caps on the ports are securely fastened to prevent water ingress.
- Keep the device's firmware updated to ensure optimal performance and security. Refer to the manufacturer's website for the latest firmware versions and update instructions.
- Clean the exterior of the device periodically with a soft, dry cloth to remove dust and debris.
7. Troubleshooting
- No Power: Check the power adapter and PoE converter connections. Ensure the power outlet is functional.
- No Wi-Fi Signal: Verify that the antennas are correctly installed and tightened. Check the device's operating mode and Wi-Fi settings in the web interface.
- Poor Signal Strength: Adjust the device's placement to minimize obstructions. Ensure antennas are oriented correctly. Consider using Repeater Mode if extending coverage over a large area.
- Cannot Access Web Interface: Ensure your computer is directly connected to the PoE converter's LAN port. Verify your computer's IP settings are compatible with the device's default IP range. Try resetting the device to factory defaults using the Reset button.
- Intermittent Connection: Check for interference from other wireless devices or electrical equipment. Ensure the Ethernet cable length does not exceed 60 meters (196 feet) to prevent power loss over PoE.
