Unfortunately, WiFi router is not enough. You also need a multichannel SDR with high bandwidth and directed antennas right near the surveilled room.
WiFi router in that overhyped scheme is just a "light bulb" to "light up" scene. WiFi AP at minimum constantly sends beacon packets to announce itself for devices around. You could receive that WiFi packets and their reflections with special SDR receiver setup with multiple antennas and eventually recreate a positions of reflectors (in this case human bodies).
So, it's not the reason to be enthusiastic. It's just yet another AI hype, noting more. You will not be able to just hack a WiFi router in some Soros NGO situation room to observe their rithuals of communication with Soros master. You will have to place several antennas and SDRs right near that room to do it, which is more problematic than placing hidden camera or direct observation.
For their demonstration, the researchers used three $30 WiFi routers and three aligned receivers that bounce WiFI signals around the walls of a room. The system cancels out static objects and focuses on the signals reflected off moving objects, reconstructing the pose of a person in a radar-like image. This was shown to work even if there was a wall between the routers and the subjects.
This approach could enable standard WiFi routers to see through a variety of opaque obstacles, including drywall, wooden fences, and even concrete walls.
Notice this also works with standard Wi-Fi equipment. I think real world you don't have to worry about it but it would serve a good purpose as a reminder to make sure your router has no hidden backdoors and only software you control.
