Native driver support makes installation easy
Get up and running quickly. Simply plug the adapter into the USB Type-C port on your laptop and connect to your network. The network adapter chipset provides native driver support in Chrome OS and Windows 8.1, and supports Mac OSX (10.10) with driver installation.

Trouble-free connections through USB-Type-C
The USB-C connector is smaller and easier to use than previous USB connectors. It's a reversible plug so you can connect to your devices with either side facing up, without frustration or the risk of port damage.
With a compact design, this USB-C network adapter is as portable as your laptop, perfect for ultra-portable devices that have a USB-C port, such as the MacBook and Chromebook Pixel. The network adapter is bus-powered which makes it easy to connect when you're on the go.
