Sony VGN-FE690 Wifi
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. A lot of newer wireless adapters are simply plug and play, in that you just plug it in the USB port and the OS will install the drivers on its own. The WiFi in your laptop, if so equipped, uses an adapter to send and receive signals to and from your router. Buying a USB wireless adapter is quick and painless because the only thing you have to know is what OS you are running on your Sony laptop.
