Play The Wifi Detective With This Powerful Free Tool

If you've ever hooked up a device to a wifi network you'll be aware of the screen which shows you the available wifi networks in your area, and their names.  But with the right software on your PC or laptop, you can pull much more data out of the air than merely a list of passing signals.  WAY more information, actually.  All you need is some wifi analysis software and, of course, a machine (desktop or laptop) that has wifi hardware built in and enabled.

One of my favourite tools for wifi analysis is Acrylic, which is available in both a free and paid version.  The free version does pretty much everything you'll need, unless you're a full-time wifi troubleshooter, and shows you loads of data about what's using the wifi spectrum in your area.  You can even monitor traffic, though be aware that most of it will be encrypted so you'll need separate tools (and additional expertise) to decipher it.  

Acrylic can be downloaded from https://www.acrylicwifi.com/en/wlan-software/wlan-scanner-acrylic-wifi-f... and it's a 6 MB download.  The program is malware-free according to VirusTotal and Web of Trust.

I may be wrong, but are you advocating using this to snoop on people.

Not that I can tell, from having re-read the article just now. No.
