USB 3.0 Fast Ethernet Adapter, 10/100Mbps, 1 x USB 2.0, 1 x RJ-45

With speeds up to 5 Gbps, USB 3.0 is fast becoming the standard in data-transfer technology for PCs and laptops. However, some computers only feature 10/100 Ethernet ports while Macbook Airs and often Ultrabooks don't feature Ethernet ports at all. Existing USB 2.0 Gigabit Ethernet adapters are limited by the USB 2.0 maximum data rate of 480 Mbps while the USB 3.0 adapter can reach speeds of 5 Gbps.
