Sony PCG-GR200 Wifi
The WiFi in your laptop, if so equipped, makes use of a wireless adapter in order to connect to your wireless router or modem. Buying a wireless adapter is quite easy because all you need to know is what OS you are running on your laptop. A lot of newer wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will install the drivers on its own. It is much simpler to buy a new wireless USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have.
