Dell Inspiron 17R Wifi
It is much simpler to buy a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. A lot of newer wireless adapters are simply plug and play, in that you just plug it in the USB port and the OS will install the drivers on its own. The WiFi in your laptop, if so equipped, uses an adapter to communicate with your router and modem. Buying a wireless adapter is quite easy because the only thing you have to know is what OS you are running on your Dell laptop.
