4. Einrichtung

The HLK-RM65 module is typically used with a development board for testing and integration. The development kit includes the module, a development board, dual-band antennas, connecting lines, and a 12V1A input adapter.

4.1. Erstmontage

1. Carefully connect the HLK-RM65 module to the designated slot on the development board. Ensure proper alignment and secure connection.
2. Attach the provided dual-band antennas to the IPEX connectors on the module. The module typically has 5 IPEX connectors for optimal Wi-Fi performance.
3. Connect any necessary peripheral devices (e.g., Ethernet cables to LAN/WAN ports, USB devices) to the development board.
4. Connect the 12V1A input adapter to the power input of the development board.

4.2. Firmware

The HLK-RM65 module comes with default OpenWrt21 firmware, supporting Linux secondary development. This allows for extensive customization and configuration of routing functionalities.

5. Bedienungsanleitung

Once the HLK-RM65 module is assembled and powered on, it functions as a routing module. The default OpenWrt firmware provides a web-basierte Schnittstelle zur Konfiguration.

1. Einschalten: Connect the power adapter. The module should power on, and indicator lights (if present on the development board) will illuminate.
2. Netzwerkverbindung: Connect a computer to one of the LAN ports on the development board using an Ethernet cable. Alternatively, search for the default Wi-Fi network broadcast by the module and connect to it.
3. Zugang Web Schnittstelle: Öffnen Sie ein web browser and navigate to the default IP address of the OpenWrt router (commonly 192.168.1.1). You may be prompted for a username and password (default credentials are often root with no password, or admin/admin).
4. Configure WAN: Set up your internet connection under the Network > WAN section. Choose your WAN access mode (PPPoE, Dynamic IP, Static IP, or 3G/4G/5G if supported by your setup).
5. WLAN konfigurieren: Navigate to Network > Wireless to configure your 2.4GHz and 5GHz Wi-Fi networks, including SSID, password, and security settings.
6. Erweiterte Einstellungen: Explore other sections for advanced configurations such as static address assignment, virtual server, port forwarding, DMZ host, and firewall rules.

6. Wartung

To ensure the longevity and optimal performance of your HLK-RM65 module, follow these maintenance guidelines:

• Umgebungsbedingungen: Operate the module within the specified working temperature range of -20℃ to +80℃. Avoid exposure to extreme temperatures, high humidity, or direct sunlight.
• Reinigung: Keep the module and development board clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or solvents.
• Stromversorgung: Always use the recommended 3.3V power supply for the module and the 12V1A adapter for the development board. Using an incorrect power supply can damage the device.
• Firmware-Updates: Regularly check for and apply official firmware updates for OpenWrt to benefit from security patches, bug fixes, and new features. Follow the instructions provided by the OpenWrt community or Hi-Link for safe updating procedures.
• Physische Handhabung: Handle the module with care to avoid physical damage. Do not apply excessive force to connectors or components.

7. Fehlerbehebung

If you encounter issues with your HLK-RM65 module, consider the following troubleshooting steps:

• Kein Strom: Ensure the power adapter is correctly connected to the development board and plugged into a working power outlet. Check the power indicator lights.
• Keine Netzwerkverbindung: Verify that Ethernet cables are securely connected. If using Wi-Fi, ensure the antennas are properly attached and that your device is connecting to the correct SSID. Try restarting the module.
• Kein Zugriff möglich Web Schnittstelle: Double-check the IP address (default 192.168.1.1) and ensure your computer's network settings are configured to obtain an IP address automatically (DHCP). Clear your browser's cache or try a different browser.
• Langsame WLAN-Geschwindigkeit: Ensure antennas are correctly installed. Check for interference from other devices. Verify your Wi-Fi channel and bandwidth settings in the OpenWrt interface.
• Modul reagiert nicht: If the module becomes unresponsive, try a hard reset by disconnecting and reconnecting the power. If the issue persists, a firmware reflash might be necessary (consult OpenWrt documentation).
