Sony VGN-SR399P Wifi
You are better off buying 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, uses a piece of hardware to send and receive signals to and from your home 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. Buying a wireless adapter is quite easy because the only thing you have to know is what OS you are running on your Sony laptop.
