Dell P22G 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 Dell laptop. Most new Wifi adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the system will install the drivers automatically. You are better off buying a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. WiFi, or wireless internet, uses a piece of hardware in order to connect to your home router.
