Sony PCV-L400 Wifi
A lot of newer wireless adapters are simply plug and play, in that you just plug it in the USB port and the operating system will take care of the rest. Buying a wireless adapter is quite easy because all you need to know is the operating system that is installed on your Sony desktop. It is cheaper and easier to purchase a new wireless USB adapter and install it, than to replace any built-in adapter your desktop may have. The WiFi in your desktop, if so equipped, uses an adapter to send and receive signals to and from your home router.
