Sony VPCW212AX Wifi
WiFi, or wireless internet, uses a piece of hardware to communicate with your wireless router or modem. A lot of newer 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. 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 wireless adapter is quite easy because the only thing you have to know is the operating system that is installed on your laptop.
