Lenovo IdeaPad S400 Touch Wifi
It is cheaper and easier to purchase a new wireless USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. WiFi, or wireless internet, makes use of a wireless adapter in order to connect to your home network. Most USB wireless adapters are plug-n-play, which means you simply plug it into a USB port and the OS will install the drivers on its own. Buying a USB wireless adapter is quick and painless because all you need to know is the current operating system on your laptop.
