Sony VGN-FW355J Wifi
The WiFi in your laptop, if so equipped, uses an adapter in order to talk to your home router. A lot of newer wireless adapters are simply plug and play, which just means that you only need to put the adapter into an available USB port and the OS will handle everything from there. Finding a WiFi adapter is easy because the only thing you have to know is the operating system that is installed on your Sony VGN-FW355J. You are better off buying a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have.
Key clues of an ineffective wireless internet adapter
