We have Nest Wifi setup. But in the past there have been occasions where we've had to factory reset it. (Touchwood) that seems more stable at the moment, but it's quite likely we'll need to do it again at some point.
But we have a number of settings - in particular fixed DHCP assignments - which are a pain to do again.
Is there still no way of backing up and restoring the settings?
There is no feature to backup or restore settings unfortunately. This is mostly a user to user community, therefore if this is important to you, I’d encourage you to also send this feedback directly to Google. You will not receive a response, unless Google need more details from you, however the team are still reading the feedback.
