Sony VGN-FW235J Wifi
The WiFi in your laptop, if so equipped, uses a piece of hardware to send and receive signals to and from your wireless router or modem. A lot of newer wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will install the drivers on its own. You are better off buying a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Buying a USB wireless adapter is quick and painless because all you need to know is what OS you are running on your Sony VGN-FW235J.
