RBR850 Continually Reboots after Firmware Upgrade V7.2.6.21_5.0.20

Thanks for posting the diagram.  Very helpful.  I am guessing that the green lines are manufactured Ethernet cables with RJ45 plugs on each end and the red line is Ethernet cable terminated at one end in an RJ45 jack on the wall and at the other end in a patch panel.

Remember, the network is stable, but Attached Devices is a problem:

If I plug the RBR into the switch with the yellow "Internet" port on the RBR it is stable but via the web GUI it shows no satellites connected and only a dozen or so devices

The network functions because it is an IP subnet.  If you are willing to ignore the Orbi Attached Devices problem and use the primary router to administer the network, leave everything alone.

Attached Devices does not display the satellites and devices connected to them because the Orbi router, even in Access Point mode, will not communicate with satellites through the WAN port.  The solution is to connect the satellites to the LAN side of the router.

Just moving the router to the basement will not make this possible because of the upstairs satellite.  In addition to one Ethernet cable connecting the router to the basement, there is one Ethernet cable connecting the upstairs switch to the basement, which will also require VLAN isolation to reach the router.

There are two solutions:

• Install a second Ethernet cable from the basement to the router to connect a router LAN port to one of the Port based VLAN ports on the basement switch.  This will avoid purchasing another managed switch so that the single cable between basement and router can carry both WAN and LAN traffic.
• Purchase another managed switch to place near the router so that the single Ethernet cable to the basement can carry both VLAN1 and VLAN2.

The cable would cost less than another switch.  Depending on the building structure, installing another cable might be almost trivial (or a nightmare!)

No matter which solution is chosen, the upstairs switch also needs to have VLAN1 and VLAN2 implemented and the port linking the upstairs switch to the basement switch needs to be a Tagged VLAN (also on the basement switch) so that both regular traffic and the router-satellite link can use the single Ethernet cable.

Netgear could have programmed the router differently, but "it is what it is".
