StarTech.com USB 3.0 to Dual Port Gigabit Ethernet Adapter NIC with USB Port (USB32000SPT)

Add Two Gigabit Ethernet Ports And A USB 3.0 Pass-Through Port To Your Laptop Through A Single USB 3.0 Port The USB32000SPT USB 3.0 to Dual Port Gigabit Ethernet Adapter lets you add two Gigabit Ethernet ports to your laptop or Ultrabook computer through a single USB 3.0 port, and features an integrated USB 3.0 pass-through port that keeps your USB port available for use with external storage or other peripherals. Each RJ45 port supports 10 / 100 / 1000 Mbps Ethernet and is fully compatible with IEEE 802.3i/u/ab standards. This two-port USB LAN adapter is a versatile solution for connecting to two separate physical networks simultaneously, leveraging the 5 Gbps speed of USB 3.0 to provide dedicated gigabit bandwidth to each port. The dual USB NIC is also ideal for providing dedicated physical network interfaces to virtual machine configurations. It's great for IT administrators that require dual-homed or multi-homed host systems.
