RBR750 and RBS750 not seeing each other with wired backhaul

What is the Mfr and model# of the host router the NG router is connected too?
RBR750
Firmware Version V4.6.14.3_2.3.12
GUI Language Version V3.0.1.54_2.1.30.3

How is the RBR connected to the host router? WAN port?
RBR is connected to the main gigE switch using a cat6 cable
RBR is set up in AP mode
The internet router is also connected to this switch
The WAN port on the RBR is not used

Whats the brand and model# of the LAN switch being used?
It's an unmanaged 8 port gigE switch from TPLink - TL-SG108S
How do the devices discover each other?

What CAT# LAN cable is being used? CAT6 is recommended.
CAT6

Try the RBS directly connected to the back of the RBR with out the switch?
Unfortunately that would be a problem with the available cabling. I might be able to work something out temporarily though. However, at that point they would be so close that I presumably wouldn't know if the backhaul was wired or wireless...?

Both devices are visible on the network - and both are providing wifi access to devices - but if they are not seeing each other, that presumably means both are acting as standalone access points....which may or may not have any real-world effect in terms of device handover etc...?

  The WAN port on the RBR is not used <The WAN port on the RBR while in AP mode HAS to be used for proper operation of the RBR AND RBS.

  Something to try as a quick test to see if the RBS sync over ethernet to the back of the RBR and they show properly when ethernet connected on the RBRs web page. Wired status should appear for each RBS after they successfully sync over ethernet.

    Ah sorry I made a mistake:
    I am (and have always) been using the RBR WAN port in AP mode.
    In AP mode then, the WAN port does not merely become another LAN port?
    
    I have connected the RBS to one of the RBR LAN ports, and the RBR now shows "12 sat connected, connection type wired"
    
    Likewise, the App shows the RBS connected
    The RBS web interface itself seems a little confused, showing the router greyed out - but maybe that is because it has no graphic for a wired connection...
    
    The fact this works might suggest that to use the wireless backhaul you have to use the RBR LAN ports - but to operate in AP mode you have to use the WAN port....so the RBR would need two cables run to it...? If so, I might go back to the old setup 🙂
    
    Thanks!
