Orbi RBR50 occasionally doesn't route Internet traffic

What is the Mfr and model# of the ISP modem? 

Has a factory reset and setup from scratch been performed since last FW update?

Fairly frequently my Internet access will stop working whether wireless or wired. Nothing will load, though whatever device I'm on shows I'm still connected to the local network and can access the Orbi via the app and the admin web page. The Orbi itself apparently still has Internet access, because it reports a connected/online status and it will successfully execute a speed test, but it's not sharing that connection with anything on the LAN side. This might happen several times a day, or not quite every day (unless it happens at a time I don't notice). It may resolve itself within 30 minutes, but it could continue hours later. Seems like sometimes it resolves right after I run a speed test from the Orbi app. When that doesn't resolve it, rebooting the Orbi seems to do the trick. This is frustrating to troubleshoot because I can't intentionally cause the issue, I haven't found a solution that always works (except rebooting), and I haven't identified any pattern to when it occurs or when it resolves itself.

 

Don't think I have a double NAT situation. My cable modem is just a modem, and the Orbi's WAN IP is a public one.

There shouldn't be anything else on the LAN that could be inappropriately issuing DHCP leases, plus all the devices on the LAN lose or regain Internet connectivity at the same time.

Nothing stands out to me in the Orbi logs, just DHCP renewals, NTP syncs, and DoS attacks that don't seem to correlate with the local outages.

 

I'm at a loss. Any thoughts?

I have a RBR50 as router and a RBS50, both firmware version 2.3.5.30.
