Driver free】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 has no access to the internet or isn’t able to read a cd driver, this would be a perfect choice.
【2 in 1 wifi and bluetooth】double antennas to gain strong signal. wifi: works with windows 7/8/8.1/10/xp, just plug and play. vista/mac os(support 10.11-10.15) needs to install the driver, install the driver via a mini cd (included). bluetooth: only for windows 7/8/8.1/10/11, not compatible with vista/xp/mac os. (the blue led light will flash when works.)
