## Summary description

The StarTech.com USB 3.0 to Gigabit Ethernet Adapter provides a wired connection via RJ-45 with a maximum data transfer rate of 5000 Mbit/s. It features a USB port and is designed for reliable network connectivity.

## Long description

The StarTech.com USB 3.0 to Gigabit Ethernet Adapter (USB31000SPTW) adds a Gigabit RJ45 network port to a laptop or Ultrabook through a single USB 3.0 port while providing an integrated USB 3.0 pass-through port to keep a USB connection available for other peripherals. The compact, USB-powered adapter supports wired network connectivity and is compatible with IEEE 802.3i/u/ab standards.
Advantages
This adapter delivers full Gigabit bandwidth over a USB 3.0 host connection and remains backward compatible with USB 2.0 systems (with speed limited by the USB bus). It supports features that reduce CPU load such as IPv4/IPv6 checksum offload and TCP large send offload. Additional capabilities include Jumbo Frames, full-duplex operation with 802.3x flow control and VLAN tagging. The integrated USB 3.0 pass-through port preserves an available USB port on the host device.
Suitable for
 Adding wired Gigabit Ethernet to MacBook, Ultrabook or laptop without an RJ45 port
 Using a portable, USB-powered network adapter for travel or remote work
 Connecting to wired networks for stable high-speed data transfer and VoIP
 Systems requiring VLAN tagging or Jumbo Frame support

How to use
Connect the adapter's USB 3.0 plug to an available USB 3.0 port on your laptop; if necessary, install drivers according to your operating system prompts. Plug a Cat5e or better Ethernet cable into the adapter's RJ45 port to establish a wired network connection. Use the integrated USB 3.0 pass-through port to connect an additional USB peripheral without occupying the host USB port used by the adapter. The adapter is bus-powered and does not require an external power supply.
Usage recommendations
For optimal performance use with a USB 3.0 port and Cat5e/Cat6 cables. When used on USB 2.0 hosts, expect reduced network throughput due to bus limitations. Ensure appropriate drivers are installed for full feature support (checksum offload, large send offload, Jumbo Frames).
