Sony PCG-FX170 Wifi
It is much simpler to buy a new USB adapter and install it, than to replace any built-in adapter your laptop may have. Buying a wireless adapter is quite easy because all you need to know is the current operating system on your laptop. WiFi, or wireless internet, uses an adapter to communicate with your router. Most USB wireless adapters are simply plug and play, which means you simply plug it into a USB port and the OS will handle everything from there.
