  • Restart your computer and network devices.
• Slow Network Speed:
  • Confirm your device's USB-C port supports USB 3.2 Gen 2 (10Gbps) or higher to achieve full 5Gbps speeds. If it's a USB 3.2 Gen 1 (5Gbps) port, the maximum speed will be limited to 5Gbps.
  • Ensure your Ethernet cable is rated for 5Gbps (Cat6 or higher).
  • Update the Realtek USB 5G Ethernet Controller (RTL8157) driver, especially for Windows and Linux systems.
  • Check your internet service plan to ensure it supports 5Gbps speeds.
  • Verify your network switch or router supports 5Gbps Ethernet.
• Adapter Not Recognized:
  • Try connecting the adapter to a different USB-C port on your device.
  • Test the adapter on another compatible device to rule out a device-specific issue.
  • Ensure your operating system is up to date.
