I'm having an issue with my Google wifi system rebooting itself randomly. Doesn't happen all the time, but annoying nonetheless.
I've contacted Google support and after reviewing the logs from the device, they've come back with the following...
"I'm seeing some authentication failure errors on the Google Wifi system. These could be caused by an upstream firewall in your fibre modem.
Talk to your ISP about DMZ mode on the OpenReach fibre modem."
Does the OpenReach ONT have any routing capabilities in it (such as a firewall, NAT, etc) or is it purely just a modem? I thought it was the latter.
I've tried their other suggestion for now...
"If that option isn't available, I recommend a 15 minute reboot of both your Google Wifi points, along with a 5 minute reboot of the OpenReach fibre modem." (basically turn it off, wait, then turn it back on again!)
