Why does blocking ICMP cause constant Orbi reboots?
OK, I'll start this by saying please do not respond if you are only going to comment, "why do you care about ICMP, why are you blocking it, etc.". This is just an academic question from my own curio...
I appreciate all the input, it's nice to see a forum where people actually help one another. While it is annoying to have 30k unnecessary pings a day in my firewall logs, I can just filter them out in the future. I did notice during some packet inspection that all of the Orbi satellites are also pinging the router, however blocking these doesn't seem to cause the Orbi to reboot for some reason, so I'll just leave those blocked.
Thanks everyone, see you all next time I have an obscure networking question.
Interesting. I had a lot of reboots in AP mode as well (would even cause the ISP modem to restart!). In Router mode, it presented more as disconnects and the ISP modem didn't reboot. It seemed to be related to IPv6 as disabling it helped, but before I could get too far testing that, support gave me some beta firmware to try.
You might sign up for the beta software and try that. It seems to have solved most of my problems although I have not tried AP mode again. And now Xfinity is doing some work / upgrades and our system is chaos, so testing anything this week is impossible. I'm lucky to get internet at all now. 🙄
Thanks for the reply. Yes, these reboots are a direct result of me blocking ICMP replies back to the Orbi while in AP Mode. If it doesn't see the ICMP reply, the Orbi reboots over and over until I unblock ICMP. I've also disabled IPv6 on all devices that I'm able to on my LAN, no real reason to run that behind NAT in my opinion. Of course my Chromecast is happily jabbering away blasting out data via IPv6, though unfortunately for it, nobody is listening 🙂
Not sure about signing up the the beta Firmware, on the one hand I do love to tinker, on the other hand I've been burned by Netgear firmware updates enough times to be wary about changing from a working firmware version. Are there any added features to the beta?

For me, stability is a feature. 🙂 It has been a huge improvement for us. The beta is low risk and very easy to revert back to the current version you are using if you don't like it. Plus, it would be interesting to see if the ICMP issue persists. But if you are otherwise happy and things are working well enough, sit back and have some popcorn.
Agreed, stability is a plus. My RBRE960 has been very stable for months, that is until I went out of town for 10 days this month. It went down 3 days afterward and didn't come back until I got home to power cycle. Sad, couldn't check in on the pet cams for a week!
I shall try the beta. I signed up for it, and it redirected to a Survey Monkey survey about current events. For shame Netgear, for shame... 🙂
Will I receive an email, it didn't link to any firmware downloads or anything like that.
So just to follow up, I signed up for the beta firmware, but there's no indication anywhere of when/if I'll get a download, where it would be located, etc. Anyone know?
