Sony PCG-F420 Wifi

It will be easier to buy a new wireless USB adapter and install it, than it is to replace any type of OEM adapter you might have. The WiFi in your laptop, if so equipped, uses an adapter to send and receive signals to and from your home network. Most USB wireless adapters are simply plug and play, which just means that you only need to put the adapter into an available USB port and the operating system will take care of the rest. 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 PCG-F420.
