3. Opsætning
The SABRENT USB-C to 2.5Gbps Ethernet Adapter is designed for straightforward installation. For most modern operating systems, it functions as a plug-and-play device, requiring no manual driver installation.
3.1. Tilslutning af adapteren
- Locate an available USB-C port on your computer, laptop, or compatible device. Ensure the port supports USB 3.0 (5Gbps/USB 3.2 Gen 1x1) or higher for optimal performance.
- Plug the USB-C connector of the adapter firmly into the USB-C port on your device.
- Connect a Cat5E Ethernet cable (or better) from your network router or switch to the RJ45 port on the adapter.
- Observe the LED indicators on the adapter. A green LED typically indicates a successful link, while a yellow LED indicates network activity.


3.2. Driver installation
- Windows, macOS, and Linux: The adapter typically installs necessary drivers automatically upon connection, especially with an existing network connection.
- Manual Driver Download: In rare cases, or for specific older operating system versions, drivers may need to be downloaded manually. Refer to the SABRENT website for the latest driver downloads and additional technical details.

4. Betjeningsvejledning
Once connected, the SABRENT USB-C to 2.5Gbps Ethernet Adapter operates automatically. Your device should recognize the new network connection and prioritize it over Wi-Fi if configured to do so.
4.1. LED-indikatorer
- Green LED (Link Indicator): A solid green light indicates a successful network link.
- Yellow LED (Activity Indicator): A blinking yellow light signifies active data transfer over the network.

4.2. Optimering af ydeevne
- Ensure your device's USB-C port supports USB 3.0 (5Gbps/USB 3.2 Gen 1x1) or a faster standard to achieve the full 2.5Gbps speed.
- Use a Cat5E Ethernet cable or higher for optimal performance over distances.
- Verify that your network router or switch also supports 2.5GbE to fully utilize the adapter's capabilities.


5. Vedligeholdelse
To ensure the longevity and optimal performance of your SABRENT USB-C to 2.5Gbps Ethernet Adapter, follow these simple maintenance guidelines:
- Hold adapteren ren og fri for støv. Brug en blød, tør klud til rengøring.
- Undgå at udsætte adapteren for ekstreme temperaturer, fugtighed eller direkte sollys.
- Forsøg ikke at adskille eller ændre adapteren, da dette vil ugyldiggøre garantien og kan forårsage skade.
- Store the adapter in a safe place when not in use to prevent physical damage to the casing or integrated cable.

6. Fejlfinding
If you encounter issues with your SABRENT USB-C to 2.5Gbps Ethernet Adapter, please refer to the following common troubleshooting steps:
- Ingen netværksforbindelse:
- Sørg for, at USB-C-stikket er sat helt i enhedens port.
- Verify that the Ethernet cable is securely connected to both the adapter and your network router/switch.
- Check the LED indicators on the adapter. If the green Link LED is off, there might be an issue with the cable or the network port.
- Genstart din computer og dit netværksudstyr (router/modem).
- Confirm that your operating system has the necessary drivers installed. If not, visit the SABRENT website for manual driver downloads.
- Langsom netværkshastighed:
- Ensure your device's USB-C port is a USB 3.0 (5Gbps/USB 3.2 Gen 1x1) or faster port. Older USB 2.0 ports will limit speed.
- Verify that your Ethernet cable is Cat5E or higher. Lower category cables may not support 2.5Gbps speeds.
- Check if your network router or switch supports 2.5GbE. If your network hardware is limited to 1Gbps, the adapter will operate at that speed.
- Temporarily disable Wi-Fi on your device to ensure the wired connection is being used.
- Adapter Gets Warm:
- It is normal for the aluminum casing to become warm during sustained high-speed operation due to efficient heat dissipation. This does not typically indicate a malfunction.
