Eh, in my experience, if you disable the uplink monitor features aggressively enough (which is in a different place in different firmwares and currently seems to also require disabling all wireless uplink/“mesh” capability), then sometime more of the network will stay up. Maybe even the gateway will keep working too if you don’t touch any gateway settings. Of course, if the gateway does decide to reboot, you’re down for many minutes.

It’s real classy.
