I think I figured this out (at least for me)

 

I was having the same issues - Orbi defaults to setting itself up in router mode (versus access point).  Since my modem is a modem/router, I disabled the wifi on my modem, set my modem up with an IP passthrough specific to the Mac ID of the Orbi router, then set the Orbi up as an access point.  Fingers crossed but so far so good, haven't been seing the issue anymore.

I would remove the RBR850 in AP mode from the IP passthru on the modem. THere would be no firewall or security in this configuration. SO you'd want to use the modems firewall for your security meaure while you have the RBR in AP Mode. FIrewall is disabled on the RBR when in AP mode.

    Didn't realize that, thanks for taking the time to reply.  Just adjusted the settings.

      AP mode on any wifi router or MESH router system, firewall is disabled.

        And if you have a router upstream from the RBR while it's in router mode, this IS a double NAT configuration which can cause these problems. Just turning OFF the wifi doesn't resolve this.
