4. Setup Instructions
This section outlines the basic steps for setting up your HLK-RM65 module, especially if using the development board kit.
- Module Installation: Carefully insert the HLK-RM65 module into the designated slot on the development board. Ensure proper alignment to avoid damage to the pins.
- Antenna Connection: Attach the provided dual-band antennas to the I-pex Generation 1 cradle connectors on the module or development board. Ensure they are securely fastened.
- Power Connection: Connect the 12V 1A input adapter to the development board's power input. Verify that the power supply meets the module's requirements (DC3.3V5A for the module itself, the adapter provides 12V for the dev board).
- Network Connections:
- For WAN access, connect your internet source (e.g., modem) to the WAN port using an Ethernet cable.
- For local network devices, connect them to the available LAN ports using Ethernet cables.
- Initial Access: Once powered on, the module should boot up. You can typically access the web configuration interface by connecting a computer to one of the LAN ports and navigating to the default IP address (refer to the module's specific documentation for the default IP).
5. Operating Instructions
After successful setup, follow these steps to configure and operate your HLK-RM65 module:
- Access Web Interface: Open a web browser on a computer connected to the module's LAN and enter the module's IP address (e.g., 192.168.1.1). Log in with the default credentials (usually admin/admin or similar, check documentation).
- Configure WAN Access: Navigate to the WAN settings. Select your internet connection type (PPPoE, Dynamic IP, Static IP, 3G/4G/5G) and enter the necessary details provided by your Internet Service Provider.
- Configure Wireless Settings: Go to the Wireless section to set up your 2.4GHz and 5GHz Wi-Fi networks. Configure SSID (network name), password, security type (WPA2/WPA3 recommended), and channel settings.
- Advanced Network Features: Explore advanced settings for specific needs:
- Static Address Assignment: Assign fixed IP addresses to specific devices on your network.
- Virtual Servers (Port Forwarding): Configure rules to direct incoming internet traffic to specific devices on your local network (e.g., for gaming servers or remote access).
- DMZ Hosts: Designate a device to be exposed directly to the internet, bypassing most firewall protections (use with caution).
- Firmware Upgrade: Periodically check for and apply firmware updates. This can usually be done via the web interface (Web page upgrade) or through a command port upgrade for advanced users.
6. Maintenance
To ensure optimal performance and longevity of your HLK-RM65 module, adhere to the following maintenance guidelines:
- Environmental Conditions: Operate and store the module within the specified temperature and humidity ranges:
- Working Temperature: -20°C to 80°C
- Storage Environment: 5°C to 40°C, 10% to 90% Relative Humidity (non-condensing)
- Power Supply: Always use a stable power supply that meets the module's voltage and current requirements (DC3.3V5A for the module).
- Firmware Updates: Regularly check the manufacturer's website for the latest firmware updates. Applying updates can improve performance, add new features, and enhance security.
- Physical Inspection: Periodically inspect the module and connections for any signs of damage, loose cables, or dust accumulation. Keep the module free from dust and debris to prevent overheating.
7. Troubleshooting
If you encounter issues with your HLK-RM65 module, try the following troubleshooting steps:
- No Power:
- Ensure the power adapter is correctly connected to both the module/development board and a working power outlet.

- No Network Connectivity (Wired):
- Check all Ethernet cable connections between the module, modem, and connected devices.
- Verify WAN settings in the web interface are correct for your internet connection type.
- Restart the module and your modem/router.
- No Wireless Connectivity:
- Ensure antennas are securely attached.
- Check wireless settings (SSID, password, security type) in the web interface.
- Verify that the wireless function is enabled.
- Try changing the Wi-Fi channel to avoid interference.
- Slow Performance:
- Check for network congestion or interference.
- Ensure the module is operating within its specified temperature range.
- Consider updating the firmware.
- Module Unresponsive:
- Perform a power cycle (unplug and replug the power).
- If accessible, try a factory reset (refer to specific documentation for reset procedure).
8. User Tips
- Linux Secondary Development: Leverage the OpenWrt21 default firmware for advanced customization and development. Familiarize yourself with OpenWrt documentation for best practices.
- Power Supply Capacity: For continuous high-load operation, ensure your 3.3V power supply can provide 5A or more to the module to maintain stability.
- Antenna Placement: Optimize Wi-Fi signal strength by carefully positioning the external antennas, avoiding obstructions.
- Security: Always change default login credentials for the web interface immediately after initial setup to prevent unauthorized access.
