Orbi RBR750 Wired Backhaul ?

[SarelErwee]

I just purchased a RBR750 with two RBS750 Satillites. I updated the firmware to the latest 4.6.5.14_2.0.54. I have the RBR750 setup in AP mode. I set the satillites MAC address in my DHCP server to for specific IP addresses and have a fix IP on the router. They all connect to the network and I can log into the router and satillites IP via a browser.
My network is somewhat complex in that I have the house vlaned. One Satilite goes through 4 switches, the other is connected via a MOCA adapter.

With the R close to the S' the wireless backhaul is setup fine. When I connect via ethernet no backhaul. I decided to try connecting the R and one of the S' with a regular switch (Netgear GS116) IE no vlan capability and still no wired backhaul. What am I missing here?

Netgear has set up a community forum specifically for the Orbi AX (WiFi 6) products. Most of the people who watch that forum are more likely to have experience with Orbi AX and know how to work it better than those of us who follow this forum. Might be more likely to find someone who has a solution if the question is posted there:

Can you provide a lay out or diagram if how your system is layed out and connected?

Are you first syncing the RBS one at a time to the RBR via wireless, then connect the RBS to the RBR using ethernet? 

I would do this first and also test the RBS directly connected to the back of the RBR via ethernet after wireless sync has completed. 

Be sure the RBR is connected to the host router using it's WAN port.
