• If using with a docking station or USB hub, ensure the hub provides sufficient power and data bandwidth.

Troubleshooting

No Network Connection:

Check Physical Connections: Ensure the USB connector is fully inserted into your computer's USB port and the Ethernet cable is securely connected to both the adapter and your network device (router/modem).

Verify LED Indicators: Check if the link/activity LEDs on the adapter are lit. If not, try a different USB port or Ethernet cable.

Restart Devices: Restart your computer, router, and modem. Sometimes a simple restart can resolve connectivity issues.

Check Device Manager (Windows): In Windows, open Device Manager and look under "Network adapters" for the StarTech.com adapter. If there's a yellow exclamation mark, it indicates a driver issue. Try updating the driver or reinstalling it.

Check Network Preferences (macOS/Linux): In macOS or Linux, verify that the new Ethernet interface is recognized and configured correctly in your network settings.

Slow Network Speeds:

Use USB 3.0 Port: Ensure the adapter is connected to a USB 3.0 port on your computer for optimal Gigabit speeds. USB 2.0 ports will limit the speed.

Check Ethernet Cable: Use a Cat5e or Cat6 Ethernet cable for Gigabit speeds. Older Cat5 cables may limit performance.

Network Congestion: High network traffic or issues with your internet service provider can affect speeds. Test with other devices on your network.

Adapter Not Recognized:

Try Different USB Port: Test the adapter in another USB port on your computer.

Test on Another Computer: If possible, try the adapter on a different computer to determine if the issue is with the adapter or your original computer.

Operating System Updates: Ensure your operating system is up to date, as this can include necessary driver updates.
