I bought an adapter to replace the adapter that was larger and had an antenna (the antenna wouldn't close the computer). Comes with an installation disk. Install driver, plug in adapter and you're done. In fact, it's a lot smaller than I expected from the picture. It's slightly larger than the USB port itself, which is great for my computer. The connection is stable and works well for what I need.
