3. Operating Instructions
The SKN-U310GT adapter is designed for plug-and-play operation on most compatible systems. Once connected and drivers are installed, your device should automatically detect the wired network connection.
Understanding Data Transfer Rates:
The actual data transfer speed can vary based on the USB port standard of your host device. For optimal performance, connect to a USB 3.2 Gen2x2 port if available.
- USB 3.2 Gen1 (5Gbps bandwidth) connection: 10G speed is not achieved.
- USB 3.2 Gen2x1 (10Gbps bandwidth) connection: Approximately 7Gbps actual measurement.
- USB 3.2 Gen2x2 (20Gbps bandwidth) connection: Approximately 9.6Gbps actual measurement (recommended for optimal experience).

5. Troubleshooting
If you encounter issues with your SKN-U310GT adapter, please refer to the following common solutions:
- No Network Connection:
- Ensure the Type-C cable is securely connected to both the adapter and your device.
- Verify the Ethernet cable is properly connected to the adapter and your router/switch.
- Check your device's network settings to ensure the wired connection is enabled.
- Try connecting the adapter to a different USB-C port on your device.
- Slow Speeds / Not Reaching 10Gbps:
- Confirm your device's USB-C port supports USB 3.2 Gen2x2 (20Gbps bandwidth) for optimal performance. Speeds will be lower on Gen1 or Gen2x1 ports.
- Ensure your router/switch and Ethernet cable (Cat6A or higher) support 10 Gigabit Ethernet.
- Driver Update: If speeds are not as expected, manually download and install the latest drivers for the Realtek RTL8159 chip from the Realtek official website.
- Mac OS Specific Note: Due to current driver display limitations, your Mac OS may show "5G" even if the actual transfer speed exceeds 5Gbps. Realtek is working on a driver update to correct this display.
- Adapter Not Recognized:
- Restart your computer or device.
- Try connecting the adapter to a different USB-C port.
- Ensure your operating system is up to date.
