Lenovo ThinkPad T440 Wifi
It is much simpler to buy a common WiFi USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. Buying a wireless adapter is quite easy because all you need to know is the current operating system on your laptop. A lot of newer wireless adapters are simply plug and play, which just means that you only need to put the adapter into an available USB port and the operating system will take care of the rest. WiFi, or wireless internet, uses a piece of hardware to communicate with your home router.
Major symptoms to watch for in a failing onboard WiFi
