Acer Aspire E5-521G Wifi
Buying a wireless adapter is quite easy because the only thing you have to know is the current operating system on your Acer laptop. Most new Wifi adapters are plug-n-play, which means you simply plug it into a USB port and the operating system will take care of the rest. It will be easier to buy a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, uses a piece of hardware to send and receive signals to and from your home router.
