USB-C Gigabit Ethernet Adapter

The Cable Matters 201213-GRY adds a wired network port to any computer with a USB-C connector. It delivers up to 1000 Mbps Ethernet speed and is backwards compatible with 10/100 Mbps networks. The adapter works with Chrome, Mac and Windows without extra drivers and supports Wake-on-LAN, MAC address pass-through and PXE boot.

Thermals and power in daily use

The unit weighs 25.515 grams and draws power directly from the host USB-C port so no external supply is needed. Passive cooling keeps it silent during sustained transfers and the aluminium housing dissipates heat without a fan. Typical operation stays cool to the touch even when streaming large video files or downloading software upgrades.

Upgrade path and when it matters

Replaces a missing or broken onboard Ethernet port on ultra-thin laptops and Chromebooks. The jump is worth it in Wi-Fi dead zones, when faster and more secure wired transfers are required, or when PXE boot and MAC cloning are needed for managed deployments. Not for users who need 2.5 Gbps or 10 Gbps Ethernet, Power Delivery pass-through or additional USB ports.

Questions about this item

How do I install the Cable Matters 201213-GRY adapter, and what step do people often miss?

Plug the USB-C connector into a Thunderbolt 3 or USB-C port; the driver installs automatically on Chrome, Mac and Windows. The step often missed is installing the Cable Matters EZ-Dock utility on Windows to enable MAC address pass-through.

What maintenance or replacement will this adapter need later?

No scheduled maintenance is required. Keep the RJ45 port free of dust and avoid bending the cable near the connector. Replace the unit only if the Ethernet link fails to negotiate at 1000 Mbps or the USB-C plug becomes loose.

What limit appears first during sustained heavy transfers?

The Gigabit Ethernet link caps throughput at 1000 Mbps, so sustained file copies or streams will hit that ceiling before the USB 3.1 Gen 1 5 Gbps host interface becomes a factor.
