Sony VPCEA3UFX Wifi
Buying a wireless adapter is quite easy because all you need to know is the operating system that is installed on your laptop. WiFi, or wireless internet, uses a piece of hardware in order to talk to your router. Most USB wireless adapters are simply plug and play, in that you just plug it in the USB port and the OS will handle everything from there. You are better off buying a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have.
