Lenovo ThinkPad T420i Wifi

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 system will install the drivers automatically. The WiFi in your laptop, if so equipped, uses a piece of hardware in order to connect to your home router. It is cheaper and easier to purchase a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Searching for a new adapter is simple due to the fact that all you need to know beforehand is the operating system that is installed on your Lenovo laptop.
