Dell Latitude C640 Wifi

Most new Wifi adapters are plug-n-play, in that you just plug it in the USB port and the OS will handle everything from there. You are better off buying a new USB adapter and install it, than to replace any built-in adapter your laptop may have. Finding a WiFi adapter is easy because all you need to know is the operating system that is installed on your Dell laptop. WiFi, or wireless internet, uses a piece of hardware in order to talk to your home network.
