Most new Wifi adapters are plug-n-play, which means you simply plug it into a USB port and the OS will handle everything from there. It is cheaper and easier to purchase a new USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. WiFi, or wireless internet, makes use of a wireless adapter to send and receive signals to and from your router and modem. Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is the current operating system on your laptop.
