good point on the basement, if they have one. The ground is quite dense.
My suggestions really have been to narrow down "is it the radio/is it my
network/is it nearby network". That's why I suggested moving to a
different location and trying. My home is rural and my cabin can't much
more rural (no other networks in sight), and I have no problems with my
radio. I suppose if my neighbor at home upgrades his router, maybe

also, when you say "where your phone reports very weak signals from
neighbors, you mean with an app such as wifi analyzer, right?

I think that doesn't work because the disruption occurs when the radio
periodically scans all the channels for access points and hits a (WiFi6
or other) signal that "confuses" the closed source secret chip firmware,
causing it to later miss transmissions from the router to the radio. The
connection then fails. 

The solution is to update the chip firmware, and an update may have been
created, but I haven't found it. The chip itself seems very capable. A
workaround might be to drastically reduce the radio's periodic scanning,
perhaps to only during too low signal strength conditions, which would
mostly or entirely eliminate the problem for radios with a solid
connection.

No need to move the router. Try your radio in a basement location where
your phone reports very weak signals from neighbors. My 2 basement
radios are in ordinary basement locations, the most interior one almost
never fails, and the other one is "better." My worst radios are near the
outside walls, where the neighboring signals are pretty strong.
