Compatibility:
This adapter is compatible with all USB-C Mac/iPad devices, Chromebooks, and other USB-C enabled laptops running compatible operating systems. For optimal performance, ensure your device's operating system is up-to-date. Minimum required operating system version for ChromeOS is 137.
4. Operating Instructions
Once connected, the HyperDrive USB-C to 2.5Gbps Ethernet Adapter functions as a standard wired network interface for your device.
Network Access:
- Your device will automatically obtain network settings (IP address, DNS servers) from your router or network server via DHCP.
- You can verify the connection status and assigned network details through your operating system's network settings.
- The adapter supports data transfer rates up to 2.5 Gigabits Per Second, provided your network infrastructure (router, cables, internet service) also supports these speeds.

5. Maintenance
To ensure the longevity and optimal performance of your HyperDrive USB-C to 2.5Gbps Ethernet Adapter, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry, lint-free cloth to gently wipe the adapter's exterior. Avoid using liquid cleaners, aerosols, or solvents.
- Storage: When not in use, store the adapter in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Avoid dropping the adapter or subjecting it to strong impacts. Do not bend or twist the cable excessively.
- Heat Dissipation: The aluminum casing is designed for efficient heat dissipation. Ensure the adapter is not covered or placed in an enclosed space during operation to allow for proper airflow.
6. Troubleshooting
If you encounter issues with your HyperDrive USB-C to 2.5Gbps Ethernet Adapter, please refer to the following common troubleshooting steps:
No Network Connection:
- Check Connections: Ensure both the Ethernet cable and the USB-C connector are securely plugged into their respective ports.
- Verify Ethernet Cable: Test the Ethernet cable with another device or replace it to rule out a faulty cable.
- Restart Device: Disconnect the adapter, restart your computer or device, and then reconnect the adapter.
- Check Device Settings: Go to your device's network settings to confirm that the Ethernet adapter is recognized and enabled. Ensure DHCP is enabled or static IP settings are correctly configured if required by your network.
- Operating System Updates: Ensure your device's operating system is fully updated, as this can sometimes resolve compatibility issues.
Slow Network Speed:
- Verify Network Infrastructure: Ensure your router, modem, and Ethernet cables (Cat5e or higher recommended for 2.5Gbps) support 2.5Gbps speeds. If any component is limited to 100Mbps or 1Gbps, your overall speed will be capped at that lower rate.
- Test with Another Port/Device: If possible, test the adapter with a different USB-C port on your device or with another compatible device to determine if the issue is with the adapter or the host device's port.
- Internet Service Provider (ISP): Confirm that your internet plan provides the expected speeds.
