Sony VPCY21BGX Wifi
Most USB wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will install the drivers on its own. You are better off buying a new USB adapter and install it, than it is to replace any type of OEM adapter you might have. Buying a wireless adapter is quite easy because all you need to know is the operating system that is installed on your Sony VPCY21BGX. WiFi, or wireless internet, makes use of a wireless adapter to send and receive signals to and from your router.
General warnings poorly running onboard WiFi
