Dell Inspiron 7420 Wifi
Searching for a new adapter is simple due to the fact that all you need to know beforehand is what OS you are running on your laptop. It will be easier to buy a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have. Most USB wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will handle everything from there. WiFi, or wireless internet, uses a piece of hardware in order to talk to your router and modem.
General indicators that your the wireless card has very little life left
- The wireless adapter in your Dell laptop will not connect to your router anymore
- The WiFi adapter driver cannot be installed
- The wireless signal disconnects and reconnects over and over again
