Sony VPCF12NGX Wifi
It is cheaper and easier to purchase a new USB adapter and install it, than to replace any built-in adapter your laptop may have. Most USB 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 operating system will take care of the rest. Buying a wireless adapter is quite easy because the only thing you have to know is the operating system that is installed on your Sony VPCF12NGX. WiFi, or wireless internet, uses a piece of hardware to send and receive signals to and from your router and modem.
