A lot of newer wireless adapters are simply plug and play, in that you just plug it in the USB port and the OS will install the drivers on its own. It is much simpler to buy a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Buying a wireless adapter is quite easy due to the fact that all you need to know beforehand is the operating system that is installed on your laptop. WiFi, or wireless internet, uses a piece of hardware to communicate with your router and modem.
