Dell Vostro 470 Wifi
It will be easier to buy a new USB adapter and install it, than to replace any built-in adapter your desktop may have. WiFi, or wireless internet, makes use of a wireless adapter to send and receive signals to and from your home router. Buying a wireless adapter is quite easy due to the fact that all you need to know beforehand is the operating system that is installed on your desktop. Most new Wifi adapters are simply plug and play, which just means that you only need to put the adapter into an available USB port and the OS will install the drivers on its own.
