I have installed the Firewalla device to my network and it worked initially and the network will not work after 1 - 2 hours.
I have a Google WiFi mesh network and I have followed the info from the compatibility page to turn on Family mode, use specific DNS and turned off guest network. But the network will be dead (all Google WiFi nodes are dead including the primary and LAN cable connection is the same) after a an hour or so.
Any tips for me to get it to work realiably?

  Disable monitoring for all devices, then progressively re-enable.

  I currently have disabled:

  • all google wifi hubs
  • all google home devices
  • ring video doorbell
  • logitech harmony hub
  • Xiaomi vacuums
  • Android wear watches

  I tried re-enabling the harmony hub and vacuums and instability returned, so both are disabled currently - I think it was the harmony hub causing issues.

  That's some nice engineering work!  We are impressed.   It is very likely it is the combination of a few things that caused the DNS problem in google wifi.  One of our customers confirmed with Google Wifi people.   Make sure you set the DNS server on google wifi to be custom.  (this was a hint given by them)

  Hi,

  
  Well yes, I'm an engineer, but I also work in quality, so I like to troubleshoot. I've avoided setting the Google Wifi DNS to custom for the time being, as then I'd lose the local DNS feature for devices on the LAN....

  Cheers,

  Paul
