A lot of newer wireless adapters are plug-n-play, in that you just plug it in the USB port and the system will install the drivers automatically. It will be easier to buy a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, uses a piece of hardware to communicate with your router and modem. Buying a USB wireless adapter is quick and painless because all you need to know is the operating system that is installed on your laptop.
