Yeah, I know.

Add to that “secret” repeaters. Take for example the Amazon Echo Chime. Combination Smart doorbell speaker/802.11n repeater (2.4GHz only).

You connect to that, good luck.

Oh and people installing repeaters not knowing how they work, putting them someplace with a piss-poor signal and putting their computer next to it, thinking it will be better now that they have “full” signal. Their laptop may have a strong signal to the repeater, but the repeater to the AP is weak, so everything connected to the repeater is weak.
