Dell Inspiron 14R 5421 Wifi
The WiFi in your laptop, if so equipped, uses a piece of hardware in order to connect to your router. You are better off buying a new USB adapter and install it, than to replace any built-in adapter your laptop may have. Buying a wireless adapter is quite easy due to the fact that all you need to know beforehand is what OS you are running on your Dell laptop. A lot of newer wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will handle everything from there.
Warnings of a dying WiFi adapter
- The WiFi adapter driver shows it as not installed
- Your WiFi in your Dell laptop will not connect to your router anymore
- The WiFi disconnects and reconnects every day

Please be sure to re-check the part number so that you correctly order the right WiFi. The Dell laptop will be better off if you buy smart! Always buy computer parts from a well-known website when you buy your parts online. Dell Inspiron 14R 5421 WiFi should really be bought in brand new condition due to possible wear on any older used one.
