Sony VGN-FS900 Wifi
The WiFi in your laptop, if so equipped, uses an adapter to send and receive signals to and from your router. A lot of newer wireless adapters are plug-n-play, which means you simply plug it into a USB port and the operating system will take care of the rest. Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is the current operating system on your Sony VGN-FS900. It is cheaper and easier to purchase a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have.
