Many newer laptops do not come with an Ethernet port, leaving users only with slow WiFi access. The USB 3.0 Ethernet Adapter & 3-Port Hub provides a wired connectivity option with lightning fast transfer speeds where wireless access isn’t available or if you have a broken internal network card. The USB 3.0 Ethernet adapter simply plugs into an available port on your laptop & supports 10/100/1000 BASE-T performance. Also included are three USB 3.0 ports for additional device expansion. The adapter is compatible with systems running Windows® 8.1/8/7/Vista/XP, as well as Mac OS® X 10.6 & later. *Requires WiFi connection to download driver
