Lenovo ThinkPad T400S Wifi
Most USB 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 OS will install the drivers on its own. It will be easier to buy a new wireless USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. Searching for a new adapter is simple because the only thing you have to know is what OS you are running on your laptop. WiFi, or wireless internet, uses a piece of hardware in order to talk to your router.
