I never got a reply from google. Zippo. I did go and update all my
google wifi nodes and repowered each after it updated successfully. I
have not had a reoccurrence. Finger crossed.
So I got a message today my internet was down and primary and one
secondary node was red. Yeti clearly was working. Did a speed test.
Failed. I made sure various apps worked and no cellular was potentially
in play. I eventually rebooted the two nodes...
