Sony VPCEA21FX Wifi

Most USB wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will handle everything from there. 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. Searching for a new adapter is simple because the only thing you have to know is the current operating system on your Sony laptop. The WiFi in your laptop, if so equipped, uses an adapter to send and receive signals to and from your home router.

Major clues of a barely functioning WiFi adapter
