Sony PCG-GRT250 Wifi
It is cheaper and easier to purchase a new USB adapter and install it, than to replace any built-in adapter your laptop may have. WiFi, or wireless internet, makes use of a wireless adapter in order to connect to your router. Searching for a new adapter is simple because all you need to know is what OS you are running on your Sony laptop. 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.
