The USB 3.0 to Gigabit Ethernet Adapter from Comprehensive adds a single RJ-45 Ethernet port to a USB enabled computer system, with support for Gigabit network connections at full bandwidth, unlike USB 2.0 adapters. This compact USB 3.0 network adapter is backward compatible with older USB 2.0/1.1/1.0 computer systems (speed limited by USB bus), making it the suitable portable replacement network adapter or laptop accessory. It is compatible with Mac OS/Windows/8/7/XP/Linux/newest Macbook Air.
