This very small device only occupies 1 USB 2.0 slot on your computer. This allows it to connect to your WiFi using a 2.4GHz or 5GHz connection. Installation is simple: insert the included CD to install drivers for the device (or download drivers from the product website if desired), then plug the device into a USB 2.0 port on your computer/laptop . From there you can connect to the WiFi. The speed depends on your internet connection
