5. Operating Instructions

Once connected, the adapter functions as a standard wired network interface. You can verify its operation and network speed through your device's network settings.

5.1 Verifying Network Connection

• Windows: Go to "Network & Internet settings" > "Ethernet" > "Change adapter options". Locate the new Ethernet adapter, right-click, and select "Status" to view connection speed and activity.
• macOS: Go to "System Settings" (or "System Preferences") > "Network". Select the USB 2.5GbE LAN adapter to see its status and IP address.
• Linux: Use network management tools or command-line utilities like ip a or ifconfig to check the status of the new Ethernet interface.

5.2 Achieving Optimal Speed

To achieve the full 2.5Gbps speed, ensure the following:

• Your router or network switch supports 2.5Gbps or higher Ethernet speeds.
• You are using a Cat5e or Cat6 Ethernet cable (Cat6 is recommended for optimal performance over longer distances).
• Your internet service provider (ISP) plan supports speeds of 2.5Gbps or higher.
• The USB-C or Thunderbolt port on your device supports USB 3.0 (or higher) for sufficient bandwidth.

6. Maintenance

The Cable Matters USB C to 2.5Gb Ethernet Adapter requires minimal maintenance to ensure longevity and optimal performance.

• Cleaning: Use a soft, dry cloth to wipe the adapter's exterior. Avoid using liquid cleaners or solvents.
• Storage: Store the adapter in a cool, dry place when not in use. Avoid extreme temperatures and direct sunlight.
• Handling: Do not bend or twist the cable excessively. Avoid pulling the adapter by its cable; always grasp the connector when plugging or unplugging.

7. Troubleshooting

7.1 No Network Connection

• Check Connections: Ensure both the USB-C connector and the Ethernet cable are securely plugged into their respective ports.
• Verify LED Indicator: Check if the LED indicator on the adapter is illuminated. If not, try a different USB-C port or device.
• Test Ethernet Cable: Try a different Ethernet cable to rule out a faulty cable.
• Restart Devices: Restart your computer/device and your network router/modem.
• Driver Check: Although plug-and-play, ensure your operating system's network drivers are up to date.

7.2 Slow Network Speed

• Check Network Infrastructure: Confirm your router/switch and Ethernet cables (Cat5e/Cat6) support 2.5Gbps speeds.
• ISP Speed: Verify your internet service plan supports the desired speeds.
• USB Port Speed: Ensure the USB-C port on your device is a USB 3.0 (or higher) port, as older USB 2.0 ports have insufficient bandwidth for 2.5Gbps.
• Interference: Minimize other network traffic or applications consuming bandwidth.

7.3 Adapter Not Recognized

• Try Another Port/Device: Test the adapter on a different USB-C port or another compatible device to determine if the issue is with the adapter or the original port/device.
• Operating System Compatibility: Confirm your operating system is listed as compatible (Windows, macOS, Linux, Chrome OS, iOS). Note that Android devices are not supported.
