USB 3.0 SuperSpeed to Gigabit Ethernet NIC Network Adapter with 3 Port USB 3.0 Hub

Tripp Lites U336-U03-GB, USB 3.0 Gigabit Network Adapter, allows you to turn a single SuperSpeed USB 3.0 computer port into an RJ45 Gigabit network port, and, creates three new additional USB 3.0 hub ports as well.

This USB 3.0-based NIC lets you connect to your home or office network at full Gigabit speeds, with support for 10/100/1000Mbps. Supports features such as Wake on LAN (WoL), VLAN tagging, and Jumbo Frames.

In addition to the Ethernet Gigabit port, the unit also adds three USB 3.0 hub ports to your system, supporting USB 3.0 speeds of up to 5 Gbps.

U336-U03-GB is backward compatible with USB 2.0 and USB 1.x standards, and will support older USB devices. It can also be used with older systems that do not have USB 3.0 ports (network speed limited by USB 1.x/2.0 bus), allowing you to utilize USB 3.0/2.0/1.x devices. Works with or without included power adapter.
