Lenovo ThinkPad X201S Wifi
Most USB wireless adapters are plug-n-play, which means you simply plug it into a USB port and the OS will install the drivers on its own. The WiFi in your laptop, if so equipped, uses an adapter to send and receive signals to and from your home router. Buying a USB wireless adapter is quick and painless because the only thing you have to know is what OS you are running on your laptop. You are better off buying a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have.
