Been having problems with Nest wifi a few days after initially setting up the devices. My Asus router has had no issues but when I switched to Google connections kept dropping. All my google home devices started dropping out and not being able to connect, smart lock, phones, etc would drop periodically... Have reverted to using the old Asus router until this is fixed. Happy to provide any additional info if needed.
Sorry about the issues you're having with your network connections. I know that's a really frustrating thing to deal with. Right now, this is a known issue and it's something we're working on with an internal team. When I know more in regards to a fix, I'll update the thread with that info.
