Sony VGN-SR420J Wifi
WiFi, or wireless internet, uses a piece of hardware to send and receive signals to and from your router. Most new Wifi 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. It is much simpler to buy a new USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is what OS you are running on your Sony VGN-SR420J.
