Add Instant Gigabit Ethernet and Triple-Port USB Expansion via a Single SuperSpeed Link
The TRENDnet USB 3.0 to Gigabit Adapter + USB Hub (TU3-ETGH3) delivers a powerful, compact peripheral docking solution engineered to bridge high-speed connectivity gaps on modern thin-profile laptops, tablets, and desktop workstations. By transforming a single vacant USB port into a dedicated, hardwired Gigabit Ethernet network connection alongside three discrete SuperSpeed USB accessory expansion ports, this versatile hub eliminates the productivity bottlenecks caused by poor wireless signals and missing interface slots.
Housed in a ruggedized, lightweight enclosure designed for mobile field kits and desktop cord management alike, the TU3-ETGH3 runs completely on standard computer line power—eliminating the need for bulky external wall chargers. Its integrated high-efficiency controller chips automatically handle full-duplex wire speeds, allowing users to safely back up large business file sets, stream ultra-high-definition media feeds, and run flash drives or input peripherals concurrently without processing drops or performance throttling.
Key Product Features
- Full Wire-Speed Gigabit Connectivity: Instantly upgrades your device with a dedicated 10/100/1000 Mbps RJ-45 LAN port for ultra-stable, low-latency gaming, streaming, and data transfers.
- 3-Port SuperSpeed Hub Expansion: Adds three additional USB ports to your system simultaneously, transferring data at speeds up to 5 Gbps—roughly 10 times faster than old legacy interfaces.
- Seamless Plug-and-Play Integration: Built with cross-platform driver architecture to automatically initialize and run on major operating systems without complex configuration steps.
- Universal Backward Compatibility: Intelligently handles mixed hardware environments, operating smoothly alongside older USB 2.0 and USB 1.1 legacy device specifications.
- Fully Bus-Powered Efficiency: Draws all operational power directly from the host computer's interface line, keeping your desktop workspace clean and mobile luggage light.
- Smart Power and Wake Logic: Equipped with advanced energy efficiency parameters, supporting Wake-on-LAN (WOL) network wake-ups and low-power idle states to conserve machine battery life.
