USB-C Gigabit Adapter for Laptops

This SMUGDESK adapter adds a wired RJ45 port to USB-C devices that lack built-in Ethernet. It supports 10/100/1000Mbps speeds for stable networking on ultrabooks, MacBooks, tablets and mini PCs. Plug-and-play operation works on most Windows, macOS and Chrome OS systems without extra drivers. Ideal for large file transfers, 4K streaming and reliable office connections.

Sustained Wired Throughput with Protection

The auto-adaptive gigabit link maintains consistent throughput during long transfers, avoiding the drops common with wireless. An integrated protection chip provides ESD and surge defence to guard against voltage spikes and signal interference during continuous use. Hot-swap capability lets you connect or disconnect without restarting the host device.

Check USB-C Port Function Before Buying

Verify that your device's USB-C port supports data or alternate-mode networking, as charging-only ports will not pass Ethernet traffic. The adapter requires an available USB-C connector and a standard RJ45 cable, neither of which is included. Systems without a USB-C interface cannot use this converter.

Questions about this item

Does the adapter draw enough power to heat up during all-day file transfers?

The USB-C gigabit LAN adapter is bus-powered and has no active cooling; normal operation stays cool to the touch during continuous wired networking.

What must my laptop already have for this RJ45 converter to work?

Your device needs a USB-C port that supports data; the adapter is plug-and-play on Windows, macOS and Chrome OS without extra drivers.

Will the 10/100/1000Mbps auto-negotiation work with my older 100Mbps switch?

Yes, the adapter auto-adapts to 10, 100 or 1000Mbps so it connects at the highest speed the switch supports.
