Sony VPCY21EFX Wifi

The WiFi in your laptop, if so equipped, uses a piece of hardware in order to talk to your home network. Most USB wireless adapters are simply plug and play, which means you simply plug it into a USB port and the operating system will take care of the rest. Buying a USB wireless adapter is quick and painless because the only thing you have to know is the current operating system on your laptop. You are better off buying a new wireless USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have.
