@FURRYe38 thanks for pointing out that the .40 "Hot Fix" is listed there in the "Top Support Articles," the fourth one down from "What can I do with the Orbi app?" and sandwiched between "What is the difference between the Orbi Whole Home AC3000 Tri-band WiFi System and the Orbi WiFi 6 System?" and "EU Declarations of Conformity." That is a place on the Support page that I would not have even given a second look because nothing relevant is ever there -- and not where I would look for firmware updates.
I think it is very odd (and totally counter-intuitive) that they don't list his "Hot Fix" among the other firmware updates; the big blue "Downloads" button takes me to a list that does not include .40 (the latest they show is .38). I think they would be doing their customers a great favor if listed this latest update in the list with the others.
Not that I would have expected this "Hot Fix" to address it, but I still struggle with the Access Control database having entries scrambled and devices randomly blocked (it happened again this morning). So, I may have to follow your standard advice (which I am not a fan of) and doing a factory reset and manually recreating the configuration (and I will be very cranky if that doesn't solve anything).
I have never owned a more buggy Netgear device (all of which were similarly configured -- this one's only uniqueness is that is is a mesh system). And I am actually considering asking "Santa Wife" for a Ubiquiti or eero system to replace this (the Orbi should not take this much care and feeding).
