5. Care and Maintenance
To ensure the longevity and optimal performance of your goobay USB-C to RJ45 Ethernet cable, please follow these care guidelines:
- Avoid Bending Sharply: Do not bend the cable at extreme angles, especially near the connectors, as this can damage internal wires.
- Store Properly: When not in use, coil the cable loosely. Avoid tight coiling or knotting.
- Keep Clean: Keep the connectors free from dust and debris. You can use a soft, dry cloth to gently wipe them if needed.
- Handle with Care: Always pull from the connector housing, not the cable itself, when disconnecting.
- Avoid Extreme Conditions: Do not expose the cable to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture.
6. Troubleshooting
No Internet Connection
- Check Connections: Ensure both the USB-C and RJ45 connectors are fully and securely inserted into their respective ports.
- Verify Router/Modem: Confirm that your router or modem is powered on and functioning correctly, and that other devices can access the internet through it.
- Disable Wi-Fi: On your device, temporarily disable Wi-Fi to ensure it attempts to use the wired connection.
- Restart Devices: Try restarting your computer/tablet and your router/modem.
- Test on Another Port/Device: If possible, test the cable with a different USB-C port on your device, or on another compatible device, to rule out a port issue.
- Check Device Settings: Ensure your device's network settings are configured to obtain an IP address automatically (DHCP).
Slow Connection Speed
- Verify Cable Rating: This cable is CAT 6, supporting up to 1 Gbit/s. Ensure your network equipment (router, modem, switch) also supports these speeds.
- Check Network Congestion: High network traffic or multiple devices using the internet simultaneously can reduce speeds.
- Test Internet Service: Perform a speed test to verify your internet service provider's actual speed.
- Update Drivers: Although plug-and-play, ensuring your device's USB-C port drivers or network adapter drivers are up-to-date can sometimes resolve performance issues.
