The adapter is built-in driver software, insert the network card, and the driver will install automatically and enable your pc to connect to the WiFi. If your computer
have no access to the internet or aren't able to read a CD driver, this would be a perfect choice.
WiFi: Works with Windows 7/8/8.1/10/XP, just plug and play. Vista/Mac OS need install the driver, install the driver via a mini CD (included).
Bluetooth: Only for Windows 7/8/8.1/10, not compatible with Vista/XP/Mac OS. The blue LED light will flash when works.
