Lenovo ThinkPad X240 Wifi
Most USB wireless adapters are simply plug and play, which means you simply plug it into a USB port and the OS will install the drivers on its own. WiFi, or wireless internet, makes use of a wireless adapter to send and receive signals to and from your wireless router or modem. You are better off buying 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 USB wireless adapter is quick and painless because all you need to know is what OS you are running on your laptop.
