Product information

Description

The StarTech.com USB 3.0 to Gigabit Ethernet Adapter (USB31000SPTB) adds a Gigabit RJ45 network port and a USB 3.0 pass-through port to a laptop or Ultrabook via a single USB 3.0 connection. It supports 10/100/1000 Mbps Ethernet and is compatible with IEEE 802.3i/u/ab standards. The compact, bus-powered adapter leverages USB 3.0 bandwidth while remaining backward compatible with USB 2.0 systems and is suitable for laptops such as Microsoft Surface Pro and Surface Book models.

Advantages

This adapter provides full gigabit bandwidth over USB 3.0 and includes an integrated USB 3.0 pass-through port so you don’t lose a USB connection when adding wired networking. It supports IPv4/IPv6 checksum offload and TCP large send offload to reduce CPU load, and features Jumbo Frames, full-duplex operation with 802.3x flow control and VLAN tagging for efficient network performance. The product is compact, bus-powered (USB), and comes with a 2-year manufacturer warranty and lifetime technical support from StarTech.com.

Suitable for

Adding wired Gigabit Ethernet to laptops and Ultrabooks without a native RJ45 port
Users who need to keep a USB port available while adding network connectivity
Microsoft Surface Pro, Surface Book and similar thin-and-light devices
Environments requiring IPv4/IPv6 offload, Jumbo Frames or VLAN tagging

How to use

Connect the adapter’s USB 3.0 plug to an available USB 3.0 port on your laptop. Attach an Ethernet cable to the RJ45 port to establish a wired network connection.
