I gave up and went with a TP-Link and their XE5300 6e mesh system.
Picked up a 3-pack on sale from Costco for under 270. Rock solid so far
and has been zero drama. Really wanted to use the Google system since
their first gen served me well for over 5...
This happened to me also. The light would just slowly pulsate yellow and
unplugging/re-plugging didn't help. App showed mesh network was great,
but I could tell from the light it wasn't. I ended up resetting the Wifi
point device and setting up again...
That's the latest one I have. It was updated 2 days ago, and ever since,
I've not had any issues. I did reboot the entire network and also
unplugged/re-plugged the main router. You might have also, but if not,
that could possibly help.
