Sony VGN-FW455J Wifi
You are better off buying a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. WiFi, or wireless internet, uses a piece of hardware in order to talk to your wireless router or modem. 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 laptop. Most USB wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will handle everything from there.
