Dell PP40S Wifi
Buying a USB wireless adapter is quick and painless because all you need to know is the current operating system on your laptop. Most USB wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will install the drivers on its own. It is cheaper and easier to purchase a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, makes use of a wireless adapter in order to talk to your wireless router or modem.
