StarTech.com Ethernet Adapter Overview

Choosing this adapter means you get the speed of a wired connection without the hassle of opening a laptop or buying a new network card. The USB 3.0 interface supplies enough bandwidth to reach the full 1 Gbps Ethernet rate, so you won’t notice any slowdown compared with a built-in port.

Because it is backward compatible with USB 2.0 and 1.x, the adapter remains useful even on older machines, though at reduced speed. The inclusion of auto-MDI/MDI-X removes the need for crossover cables, and the two-year warranty plus lifetime technical support give you peace of mind.
