It is cheaper and easier to purchase a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have. A lot of newer wireless adapters are simply plug and play, which just means that you only need to put the adapter into an available USB port and the OS will handle everything from there. The WiFi in your laptop, if so equipped, uses an adapter to send and receive signals to and from your home network. Searching for a new adapter is simple because the only thing you have to know is what OS you are running on your laptop.
