How to use
Plug the USB-A connector into an available USB 3.0 port on your computer, then connect an Ethernet cable between the adapter’s RJ45 port and your switch, router or wall outlet.

To achieve and maintain 2.5G performance, use quality Cat5e or better Ethernet cabling, verify that connected switches/routers support 2.5G, and connect the adapter to a USB 3.0 (or higher) host port. Avoid prolonged operation in poorly ventilated areas to minimize heat buildup.
