How to find a lost wi-fi hotspot?

Question

WiFi

There is a wi-fi dish that is disconnected from the local network, but we don’t know where it is) Periodically connects to another dish via wi-fi, but the radius is very large, everyone climbed around. How can you find it?

Answer 1

Can I log in to an unknown point (when it connects)? What is the model of one and the other point? If some kind of Ubiquity, then it even shows the approximate distance to a neighboring point. And there is also Site Survey and Discovery for diagnostics, it could help.
If a known point has a directional antenna, then you can do radio direction finding (sounds cool). You can wait for the connection of the unknown and slowly turn the known first to the right, until the unknown falls off, detect the azimuth; then return to its original position, wait for the connection and turn left until it falls off, detect the azimuth. Take the bisector of the angle between the extreme positions and look in that direction.
And if you can remove a known point from the building (or take another point with a directional antenna, set it up in the same way - the same channel, SSID, login, password) and organize mobile power for it and connect to a laptop, then you can walk around the territory, make several of these bearings from different points and this will allow you to quickly and accurately go to the neighborhood.

Answer 2

If possible, try the method of electricians.
Is she inquiring somewhere?
Install the WiFi Analyzer program on your smartphone, take a walk around the territory and try to localize according to the signal level (after changing the SSID at other points so as not to interfere)
