RBR50 - CPU 100% then reboot after reboot
Ok, finally hopefully making progress....been doing a ton of reading. It looks like there are issues out there, but can't find a difinitive fix.
I uploaded screen shoots of my CPU.
I have about 30-40 connected devices, most are "Alexa enabled smart swith, light, outlets, etc.
For years had no issues, then randommly (did not add anything new) I would get internet drops. Thought it was ISV (Spectrum) and while still might be an issue, I know my CPU should not spike to 100% and then stay their till I power cycle everything.
Any ideas what to do next ?
Router Firmware Version on all 3 devices.

Network devices going to 100% CPU looks suspiciously like a "Broadcast Storm" where broacast packets are being repeated by the thousands until they overwhelm the network. In corporate environments, it was critical to avoid creating "loops" where there were two pathways between devices. Are there any switches or wired devices connected to the Orbi? Any devices connected simultaneously by wire and WiFi?
Wow, yes I do have a switch connected to my Orbi and then a few laptops connected to Cat5 via that Switch....this was never a problem, but perhaps something changed.
As for connected via wifi and cat5...nor normally but at times my main laptop is.
Is taking the switch out of the equation the 1st natural step ?

It is very common to have switches as part of an Orbi system (I have two: one connected to the router and one connected to a satellite.)
It also is very common to have 40-50 devices connected to an Orbi. One user reported over 100 devices!
Rather than disconnect the switch, it might be a good experiment to power off one device at a time and see how that affects the CPU load.
Of course, this would have to be done when the CPU load has gone crazy.
Tyr downgrading to v16...
