## Summary description

StarTech USB 3.0 to Gigabit Ethernet adapter (model USB31000SPTB) provides wired network connectivity over a USB host interface with up to 5 Gbit/s transfer rate. The compact, USB-powered NIC includes an additional USB port and an Ethernet RJ45 interface, suitable for adding gigabit LAN to laptops, desktops or thin clients without built-in Ethernet.

## Long description

The StarTech USB 3.0 to Gigabit Ethernet Adapter with Extra USB Port (USB31000SPTB) adds a wired Gigabit LAN connection to computers that lack a built-in Ethernet port. This compact, USB-powered network adapter connects to a host via USB 3.0 and provides an RJ45 Ethernet interface that supports 10/100/1000 Mbps operation and compliance with IEEE 802.3i/u/ab standards. An integrated USB 3.0 pass-through port preserves your computer’s USB availability while delivering up to 5 Gbps of USB host bandwidth for full gigabit throughput when used with a compatible USB 3.0 host.
Advantages
The adapter delivers full Gigabit bandwidth over a USB 3.0 connection while remaining backward compatible with USB 2.0 hosts (with speed limited by the USB bus). It includes an additional USB 3.0 pass-through port so you do not lose a usable USB port when adding wired networking. The unit is USB-powered and portable, making it suitable as a replacement LAN adapter or a convenient accessory for laptops, ultrabooks and thin clients.
Suitable for
Adding a Gigabit Ethernet port to laptops and Ultrabooks that lack built-in LAN
Providing wired network access for thin clients and compact desktops
Using with Microsoft Surface devices and similar systems that have limited ports
Temporary or mobile network connections where a compact, USB-powered adapter is needed

How to use
Connect the adapter to an available USB 3.0 port on your computer and plug an Ethernet cable into the RJ45 port. If required by your operating system, install the appropriate driver software provided by StarTech or via the OS update mechanism. Use the integrated USB port to connect another USB device so you retain access to a USB connection while the adapter is attached. The adapter is bus-powered and requires no external power supply.
Usage recommendations
For maximum network performance, connect the adapter to a USB 3.0 port and use Cat5e or higher Ethernet cabling. On older USB 2.0 hosts expect reduced throughput due to host interface limitations. Keep drivers up to date to ensure compatibility and to take advantage of features like checksum offload and VLAN tagging.
