A lot of newer wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will install the drivers on its own. The WiFi in your laptop, if so equipped, makes use of a wireless adapter to communicate with your router. It is much simpler to buy a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. Buying a wireless adapter is quite easy because the only thing you have to know is the current operating system on your laptop.
