Dell Inspiron 15-N5040 Wifi
WiFi, or wireless internet, makes use of a wireless adapter in order to talk to your wireless router or modem. Buying a USB wireless adapter is quick and painless because the only thing you have to know is what OS you are running on your laptop. You are better off buying a new USB adapter and install it, than to replace any built-in adapter your laptop may have. Most USB wireless adapters are plug-n-play, which means you simply plug it into a USB port and the OS will install the drivers on its own.
Elements of a weakening onboard WiFi
