Sony VPCZ21DGX Wifi

The WiFi in your laptop, if so equipped, makes use of a wireless adapter to communicate with your wireless router or modem. You are better off buying a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. Buying a wireless adapter is quite easy due to the fact that all you need to know beforehand is what OS you are running on your Sony laptop. Most USB wireless adapters are plug-n-play, in that you just plug it in the USB port and the operating system will take care of the rest.
