Acer Extensa 4620 Wifi
Buying a USB wireless adapter is quick and painless because all you need to know is the current operating system on your laptop. 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. WiFi, or wireless internet, uses a piece of hardware to communicate with your home network. Most new Wifi adapters are simply plug and play, which just means that you only need to put the adapter into an available USB port and the operating system will take care of the rest.
