Lenovo ThinkPad T540P Wifi
It is much simpler to buy a new 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 router. Searching for a new adapter is simple due to the fact that all you need to know beforehand is the current operating system on your Lenovo laptop. A lot of newer wireless adapters are simply plug and play, in that you just plug it in the USB port and the OS will handle everything from there.
