5. Setup

Follow these steps to set up your Gembird USB-C Gigabit Network Adapter:

  1. Connect to Host Device: Plug the USB-C connector of the adapter into an available USB-C port on your laptop, tablet, or computer.
  2. Connect to Network: Insert an Ethernet cable (RJ45) from your router or modem into the Gigabit Ethernet port on the adapter.
  3. Connect USB Peripherals: Plug your USB devices (e.g., flash drives, external hard drives, mouse, keyboard) into the three available USB 3.1 ports on the adapter.
  4. Driver Installation: The adapter is typically plug-and-play. Your operating system (Windows, macOS, Linux, Chrome OS) should automatically detect and install the necessary drivers. If prompted, allow the system to install drivers.

6. Operating Instructions

Once connected, the adapter functions automatically:

  • Network Access: Your host device should now have a wired network connection. You can verify this in your operating system's network settings.
  • USB Device Access: Connected USB peripherals will be recognized by your host device and function as if directly connected.

7. Troubleshooting

If you encounter issues, refer to the following common problems and solutions:

  • No Network Connection:
    • Ensure the Ethernet cable is securely connected to both the adapter and your router/modem.
    • Check your router/modem for proper operation.
    • Verify network settings on your host device.
    • Try connecting the adapter to a different USB-C port on your host device.
  • USB Devices Not Recognized:
    • Ensure USB devices are properly plugged into the adapter's USB 3.1 ports.
    • Try connecting the USB device directly to your host computer to confirm it is functional.
    • Some high-power USB devices may require an external power source if your host device's USB-C port does not provide sufficient power (this adapter does not have a dedicated power input).
  • Slow Network Speed:
    • Ensure your Ethernet cable is rated for Gigabit speeds (Cat5e or higher).
    • Verify your internet service provider's speed and your router's capabilities.
    • Ensure your host device's USB-C port supports USB 3.0/3.1 speeds.
