Sony VPCY21SFX Wifi

The WiFi in your laptop, if so equipped, uses an adapter to send and receive signals to and from your wireless router or modem. Most new Wifi adapters are simply plug and play, which means you simply plug it into a USB port and the OS will install the drivers on its own. Buying a USB wireless adapter is quick and painless because all you need to know is the operating system that is installed on your Sony laptop. It will be easier to buy a common WiFi USB adapter and just plug it in, than to replace any built-in adapter your laptop may have.

Some warnings your internal WiFi has little time left

The wireless adapter driver shows it as not installed
The WiFi adapter on your laptop cannot see the SSID coming from your router
Your WiFi signal goes out randomly over and over again
