Every network, sorted against your list
We load the show's approved networks before doors. Anything using your network name from hardware that isn't yours shows red. Unknowns show orange, with hints like phone hotspot or travel router.
One handheld does it: our Harogic PXN spectrum analyzer with a Wi‑Fi adapter and a directional panel antenna mounted on it. It works as a normal analyzer until we need to hunt; then one tap switches it to eighty32 HuntBox. The demo below plays out a hunt for a copycat of the show network.

Turning the handheld in a slow circle gives a direction. Do it again from another aisle and the lines cross on the floor plan, with a circle sized honestly to the uncertainty.
Inside the circle, the level and an audible tone climb as you get closer. In a crowded hall, reflections off truss and LED walls mean the fix gets you to the zone and the tone finishes the job.
Illustration. The device drawing is schematic and the hunt is simulated; on a real floor, timing depends on the hall.
