Startech 3 Port USB 3. 0 Hub with Gigabit Ethernet Add Gigabit Ethernet connectivity and 3 USB 3. 0 Hub ports to a computer through a single SuperSpeed USB 3. 0 port. The ST3300U3S USB 3. 0 Gigabit Network Adapter turns a single SuperSpeed USB 3. 0 host connection port into an RJ45 Gigabit network port as well as three additional USB 3. 0 hub ports. Unlike a USB 2. 0-based adapter, this USB 3. 0-based NIC lets you connect to your home or office network at full Gigabit bandwidth, with support for 10/100/1000Mbps. Plus, with support for features such as Jumbo Frames, VLAN tagging and Wake on LAN (WoL), this versatile network adapter offers a comprehensive Gigabit network solution. On top of Gigabit Ethernet connectivity, the adapter also adds three USB 3. 0 hub ports to your system, which allow you to connect external storage or other USB peripherals locally to the host computer. The hub ports support USB 3. 0 speeds of up to 5 Gbps, as well as fast charging for mobile devices (e. g. iPhone�, iPad� and most Android� devices). Backward compatible with USB 2. 0 and USB 1. x standards, the Gigabit Adapter/USB 3. 0 hub will still support older USB devices and can also be used with an older system that does not have USB 3. 0 ports (network speed limited by USB 1. x/2. 0 bus), allowing you to mix and match USB 3. 0/2. 0/1. x devices. For further portability, the adapters can be used with or without the included external power adapter, eliminating the hassle of having to find an available wall outlet. Backed by a StarTech. com 2-year warranty and free lifetime technical support.
