4.3 Antenna Connection
- Attach the four provided 2.4G/5G antennas to the corresponding antenna connectors (ANT1, ANT2, ANT3, ANT4) on the adapter enclosure.
- Ensure the connections are secure but do not overtighten.
4.4 Power and Data Connection
- Connect the adapter to your computer using the provided USB 3.0 cable. Insert one end into the USB 3.0 port on the adapter and the other into a compatible USB 3.0 port on your PC.
- For auxiliary power, connect the provided Type C cable to the "TYPE C PWR" port on the adapter and to a suitable power source (e.g., a USB charger or another USB port on your PC). The "USB PWR" port can also be used for power only.
- Close the adapter enclosure securely.

5. Operating Instructions
Once the adapter is connected to your PC with the M.2 module and SIM card installed, your operating system should detect the new hardware.
- Driver Installation: Your operating system may automatically install necessary drivers. If not, you may need to download and install drivers for your specific M.2 4G/5G module from its manufacturer's website.
- LED Indicators:
- USB PWR LED: Indicates power supply via USB.
- TYPE C PWR LED: Indicates power supply via Type C port.
- WAN LED: Indicates network activity.
- 3.3V LED: Indicates 3.3V power supply to the module.
- Fan Control: The integrated cooler fan has an independent ON/OFF switch. Turn it ON for active cooling, especially during prolonged use or high data transfer rates, to maintain optimal module temperature.
- Reset Switch: A reset button is available to restart the adapter if needed.
- Network Configuration: After successful driver installation, configure your cellular network settings through your operating system's network control panel. This typically involves setting up an APN (Access Point Name) provided by your mobile network operator.
6. User Tips
- Not a Router: This device is an adapter, not a standalone 5G network cell router. It enables your computer to use a 5G module for internet access, similar to an external modem. Your computer will then manage the connection.
- Module and SIM Required: Always remember that both a compatible 3G/4G/5G M.2 module and an active SIM card are essential for the adapter to function as intended.
- Check Module Compatibility: Before purchasing an M.2 module, ensure it is compatible with the adapter (e.g., Quectel RM500Q/RM500U, Gosuncn GM800, Sierra SIM8200, and M.2 Key B 3042/3052 dimensions).
- Proper SIM Size: Use a standard SIM card. If you have a MicroSIM or Nano SIM, you will need a suitable adapter to fit it into the standard SIM slot.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not recognized by PC | Loose USB connection; Missing or incorrect drivers; M.2 module not properly installed. | Ensure USB 3.0 cable is securely connected. Install appropriate drivers for your M.2 module. Re-seat the M.2 module in its slot. |
| No network connection | SIM card not installed or inactive; M.2 module not functioning; Antennas not connected; Incorrect network settings (APN). | Verify SIM card is correctly inserted and active. Check M.2 module installation. Ensure all four antennas are securely attached. Configure APN settings in your OS. |
| WAN LED not lighting up | No active network connection; M.2 module issue. | Check SIM card status and network coverage. Ensure M.2 module is correctly installed and drivers are loaded. |
| Cooler fan not spinning | Fan control switch is OFF; Power issue. | Ensure the independent fan control switch is in the ON position. Verify the adapter is receiving sufficient power. |
| Slow network speeds | Poor signal strength; Network congestion; M.2 module overheating. | Relocate the adapter for better signal reception. Ensure the cooler fan is ON to prevent overheating. Contact your mobile network provider if issues persist. |
8. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the adapter. Avoid using liquid cleaners or solvents.
- Dust Prevention: Keep the adapter in a clean, dust-free environment to prevent dust buildup on the fan and internal components, which can affect cooling efficiency.
- Airflow: Ensure that the adapter's vents are not obstructed to allow for proper airflow and cooling.
- Handling: Handle the adapter with care. Avoid dropping it or subjecting it to strong impacts.
