Orbi RBK753 enters a boot loop every time the uplink goes down

Which WAN connection is this:

The connection to the pfSense box? or
The connection between pfSense box and the RBR750?

It's the first option.

I mean, I try to do various settings to implement some level of parental controls. Sometimes, I get that wrong and the opnsense doesn't allow either outgoing or incoming traffic to the internet.

Yesterday, to test the LED behavior, I did that intentionally and just cut internet access for only the IP of the Orbi router (not the satellites). The Orbi started to reboot, but everything else was working in between.

But so far, I never had an instance where the opnsense itself was unreachable through the Orbi because of routing settings.

So, for some seconds in between reboots, the opnsense is always reachable, which is how I eventually manage to restore the connection.

If it is the link between pfSense box and the RBR750 then, of course, it is impossible to reach the pfSense box from anything connected to the Orbi 750 system.

That was unclear wording on my side. Routing wise, the opnsense is always reachable.

But I see the Orbi going off air, all wirelss connections lost on all devices, SSID absent for all devices, then after some seconds, all 3 SSIDs back (normal, IOT, Guest, even though the router itself doesn't have an option for IOT network in the settings, and this thing where all 3 are visible for a while is weird, but whatever), then only the normal SSID is on air, works for some seconds, then the cycle repeats.

Definitely strange. The 750 user manual says:

Indeed. But I guess where there's room for one bug, there's room for one more.

Maybe the router just resets the WiFi module, while the OS itself keeps running. Although, I would expect that to be a shorter operation than the durations I see.

I'll try a factory reset as FURRYe38 suggested, I just need to find some time.

I was hoping to avoid this, because the pairing of satellites is honestly not the most seamless operation.
