Dell Inspiron 14R 7420 Wifi
The WiFi in your laptop, if so equipped, uses a piece of hardware in order to connect to your wireless router or modem. Most USB wireless adapters are simply plug and play, in that you just plug it in the USB port and the OS will handle everything from there. Finding a WiFi adapter is easy due to the fact that all you need to know beforehand is the current operating system on your laptop. It is cheaper and easier to purchase a new wireless USB adapter and install it, than it is to replace any type of OEM adapter you might have.
