Sony PCG-FX270 Wifi
Most USB wireless adapters are plug-n-play, which means you simply plug it into a USB port and the OS will handle everything from there. It is much simpler to buy a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, uses an adapter in order to connect to your router and modem. Finding a WiFi adapter is easy because all you need to know is the current operating system on your laptop.
