It is cheaper and easier to purchase a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. Buying a USB wireless adapter is quick and painless because the only thing you have to know is the operating system that is installed on your laptop. WiFi, or wireless internet, makes use of a wireless adapter in order to talk to your router. Most USB wireless adapters are plug-n-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.
