Sony PCG-SR21K Wifi

The WiFi in your laptop, if so equipped, uses an adapter to communicate with your home network. It will be easier to buy a new USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. A lot of newer 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. Searching for a new adapter is simple because all you need to know is the current operating system on your laptop.

Warnings your internal WiFi will not last the year

The WiFi goes out randomly all the time
The laptop wireless driver suddenly shows as uninstalled
