Dell Inspiron 15R 5520 Wifi
Most new Wifi adapters are plug-n-play, which means you simply plug it into a USB port and the OS will install the drivers on its own. Buying a wireless adapter is quite easy due to the fact that all you need to know beforehand is what OS you are running on your laptop. It will be easier to buy a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, makes use of a wireless adapter to communicate with your router.
