Description
This item is brand-new, factory sealed.
Add a Gigabit network port to your computer, using a USB Type-C connection. The RJ45 port supports multiple speeds (10/100/1000 Mbps) and is fully compatible with Cat5 (and higher) cabling.

1 Gigabit Network Connection
This adapter supports both current and legacy Ethernet networks down to 10Mbps, making it ideal for providing a reliable network connection almost anywhere whether at home, work or while traveling.
