Do most consumer APs/routers allow you to just change the MAC address on the fly? I don't think the ones I've owned have ever allowed that. But that would certainly be interesting to try (if you were somewhere without any other address interference that would tip it off)

Pretty sure the laptop I had from like 2012 until 2018 could do that. Haven't tried anymore since (haven't played around with deauths) but I thought this was common functionality

Consumer router firmware UIs, typically owned by ISPs, I'd not expect that yeah. Some don't even let you pick a WiFi band anymore and require other changes to be submitted through an ISP portal on the web somewhere (thinking of Belgium here, not sure which ISP it was)

Some will let you change it but it's almost always static since changing AP MAC Address will cause network disruptions for all connected clients.

Sure, some hacker somewhere will screw with these databases by rotating their AP MAC Address regularly but 99.9% are not going to touch it and 99.9% is good enough for location databases.
