RT-AX57 occasionally broadcasting hidden SSID

[Salting]

Hi, just set up the RT-AX57 and was checking channels on Wifiman. Noticed this hidden SSID that broadcasts occasionally. Anyone know what its for?

I live in a small condo complex and see numerous Hidden SSID's on Wifi Analyzer. Obviously a neighbor with a couple of tri-band routers..I just make sure to use a different channel to avoid interference..
