Lenovo S21E-20 Wifi
It is cheaper and easier to purchase a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. A lot of newer wireless adapters are simply plug and play, in that you just plug it in the USB port and the operating system will take care of the rest. Buying a wireless adapter is quite easy because all you need to know is the current operating system on your laptop. WiFi, or wireless internet, uses an adapter to communicate with your router and modem.
