It is much simpler to buy a new USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. 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. Buying a wireless adapter is quite easy because all you need to know is the operating system that is installed on your laptop. The WiFi in your laptop, if so equipped, uses an adapter to send and receive signals to and from your home network.
