I’m also having problems with a recent change to my network, with the similarity being the addition of a new Google Nest Wifi ‘installation’ -
Network problem: MS Surface Pro 7 (Remote) intermittent connection with Google Nest WiFi - and Core.
My problem is with occasional disconnection of my WiFi-connected Remote.
I suspect that the ‘Mesh’ having its own subnet might be the culprit.
