4. Setup Guide

4.1 Hardware Installation

1. Attach Antennas: Carefully screw all six detachable antennas onto their respective connectors on the back of the router. Ensure they are finger-tight.
2. Insert SIM Card(s): Locate the external Nano SIM card slot(s) on the front panel. Insert your Nano SIM card(s) into the slot(s) until they click into place. If using two SIM cards for dual modem functionality, ensure both modems are installed internally (refer to advanced setup if modems are not pre-installed).
3. Connect Ethernet Cables (Optional):
   • Connect your internet source (e.g., fiber modem, DSL modem) to the WAN port (typically labeled 'WAN').
   • Connect your wired devices (e.g., PC, gaming console) to any of the LAN ports (labeled 'LAN1' to 'LAN4').
4. Connect Power: Connect the provided power adapter to the DC IN port on the router and then plug it into a power outlet. The router will power on automatically.

4.2 Initial Network Connection

Once powered on, wait for the router's indicator lights to stabilize (typically Power, 4G, and Wi-Fi indicators). You can connect to the router via:

• Wired Connection: Use an Ethernet cable to connect your computer to one of the router's LAN ports.
• Wireless Connection: Search for the router's Wi-Fi network name (SSID) on your device (laptop, smartphone). The default SSID and password are usually printed on a sticker on the bottom of the router. Connect using the provided password.

4.3 Accessing the Router Interface

To configure advanced settings, access the router's web interface:

1. Open a web browser (e.g., Chrome, Firefox).
2. In the address bar, type the default IP address of the router (commonly 192.168.1.1 or 192.168.0.1) and press Enter. Refer to the 4G Common Manual for the exact default IP and login credentials.
3. Enter the default username and password (also found on the router's sticker or in the manual).
4. You will now be in the OpenWRT management interface, where you can configure Wi-Fi settings, network modes, firewall rules, and more.

5. Operating Instructions

5.1 Basic Wi-Fi Operation

• Connecting Devices: Use the Wi-Fi network name (SSID) and password to connect your wireless devices.
• Changing Wi-Fi Settings: Log into the web interface to change your SSID, password, security type (WPA2/WPA3 recommended), and channel settings for both 2.4G and 5G bands.

5.2 4G/LTE Connectivity

• The router will automatically detect and connect to the 4G network via the installed SIM card(s).
• Monitor the 4G indicator light on the router for connection status.
• In the web interface, you can view 4G signal strength, data usage, and switch between SIM cards if multiple modems are installed and configured.

5.3 Dual SIM Functionality (with Dual Modems)

If you have installed two compatible 4G modems, the router supports dual SIM functionality. This allows for failover or load balancing between two different cellular networks. Configuration for this feature is done through the OpenWRT web interface.

6. Maintenance

• Firmware Updates: Regularly check the manufacturer's website for firmware updates. Updating firmware can improve performance, add new features, and fix security vulnerabilities. Follow the instructions provided with the firmware update carefully.
• Cleaning: Keep the router clean and free from dust. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or aerosols.
• Ventilation: Ensure the router is placed in a well-ventilated area. The all-metal body is designed for heat dissipation, but proper airflow is still important for optimal performance and longevity.
• Resetting the Router: If the router becomes unresponsive or you forget your login credentials, you can perform a factory reset by pressing and holding the 'Reset' button (usually a small pinhole button) for about 10 seconds while the router is powered on. This will revert all settings to their factory defaults.

7. Troubleshooting

• No Power: Ensure the power adapter is securely connected to both the router and a working power outlet. Check the power indicator light.
• No Internet Connection:
  • 4G/LTE: Check if the SIM card is correctly inserted and activated. Verify the 4G signal strength in the web interface. Ensure your 4G modem(s) are properly installed and recognized.
  • WAN (Ethernet): Ensure the Ethernet cable from your internet source is securely connected to the WAN port. Check the WAN indicator light.
• Wi-Fi Not Connecting:
  • Verify that Wi-Fi is enabled on your devices and the router.
  • Check the Wi-Fi password.
  • Ensure your device is within the router's Wi-Fi range.
  • Try restarting the router.
• Slow Internet Speed:
  • Check your 4G signal strength or WAN connection speed.
  • Reduce the number of connected devices or bandwidth-intensive activities.
  • Consider changing Wi-Fi channels in the router's settings to avoid interference.
• Cannot Access Router Interface:
  • Ensure your device is connected to the router (wired or Wi-Fi).
  • Verify the router's IP address.
  • Clear your browser's cache or try a different browser.
  • If all else fails, perform a factory reset (see Maintenance section).

8. User Tips

• Dual SIM Card Functionality: If you intend to use two SIM cards for dual modem operation, you MUST order the router with two modems. If you only order one modem, only one SIM card slot will be functional.
• Modem Compatibility: When installing two modems for dual SIM functionality, ensure both modems are of the same type and compatible with the router for proper operation.
• Antenna Placement: For optimal Wi-Fi and 4G signal, position the router in a central location, away from obstructions and sources of interference. Adjust the antennas for best reception.
• OpenWRT Customization: The OpenWRT system offers extensive customization options. Familiarize yourself with its features to optimize your network for specific needs, such as VPN, advanced routing, or network monitoring.
