USB Type-C to RJ45 Ethernet Adapter MediaRange MRCS237, Gigabit 10/100/1000 Mbps, 20 cm, Black

MediaRange MRCS237 is a compact USB Type-C to RJ45 Ethernet adapter that delivers wired Gigabit network connectivity (10/100/1000 Mbps) for devices without a built-in Ethernet port. The adapter uses a USB Type-C host interface and is USB powered, with a 20 cm black cable that provides a short, unobtrusive connection between a laptop, tablet or other compatible device and a wired network.

Advantages

The adapter provides stable, high-speed wired networking up to 1000 Mbit/s, reducing latency and packet loss compared with typical wireless connections. It is plug-and-play with common desktop and mobile operating systems, requiring no additional drivers in most environments. Its compact 20 cm design and black housing make it easy to carry and integrate into existing workstations without adding bulk.

Suitable for

• Connecting laptops or tablets without Ethernet ports to a wired LAN for reliable internet access
• Video conferencing and VoIP where low latency and stable throughput are required
• File transfers and backups over a local network at Gigabit speeds
• Temporary wired connections in hot-desk, home office or meeting-room setups

When it may not be suitable

This adapter is intended for devices with a USB Type-C host port; it will not work with devices lacking a compatible USB-C connector or with USB-C ports that do not support data transfer. It is a single-port adapter designed for Ethernet only and does not provide additional ports such as HDMI, USB-A or power delivery passthrough.

Key specifications

• Interface: USB Type-C (host) to RJ45 (Ethernet)
• Maximum data transfer rate: up to 1000 Mbit/s (Gigabit Ethernet)
• Supported speeds: 10/100/1000 Mbps
• Cable length: 20 cm
• Power: USB powered (no external power adapter required)
• Colour: Black

How to use

Insert the USB Type-C plug into a compatible device USB-C port and connect a standard Ethernet cable to the RJ45 socket on the adapter. The device should detect the wired connection automatically on Windows, macOS and many Linux distributions; configure network settings through the operating system if required. No separate power source is needed, as the adapter draws power from the host device.

What to consider before purchase

• Ensure your device has a USB Type-C port that supports data transfer.
• Check that Gigabit Ethernet is required for your use case; if only 100 Mbps is needed, the adapter still functions but offers higher capability.
• Confirm compatibility with your operating system; while plug-and-play in most cases, specific environments may require driver support.

Recommendations

For consistent Gigabit performance, use a quality Cat5e or higher Ethernet cable and connect to gigabit-capable network equipment. Keep the short cable run free of tension and avoid sharp bends to preserve the connector and ensure reliable operation.
