Lenovo S40-70 Wifi
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 OS will handle everything from there. WiFi, or wireless internet, uses an adapter in order to talk to your wireless router or modem. It will be easier to buy a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is what OS you are running on your Lenovo laptop.
