So I have had this for some time  The satellites are all connected via wire and all switches are gigabit wired.  I have 500/500 fiber.  It tests this speed at the router. The GUI of the router is sl...

My vote is for a typo.  It is fortunate but frustrating that Netgear has customers in almost every county.  It can be quite some time before the Original Poster discovers a reply.

I bought a three unit system RBR840 with two RBS840 sats from costco and added the two RBS750 that came with an older three system orbi mesh.  When I called tech years ago when I got the RBR840 they told me the two RBS750s would work.  They have and do show up as satellites.

    What is RBR8? RBR should be RBR###

    Sorry RBR840

    What web browser are you using? Happens in other browsers? 

    Tried with two browsers and a hardware unit called FING

     

    What FW version is loaded on the RBR and all RBS? 

      Model Name Device Name Current Firmware Version Status
    RouterRBR840Matrix0007V4.6.14.5No New Firmware Available
    SatelliteRBS750Green RoomV7.2.6.21No New Firmware Available
    SatelliteRBS750Theater RoomV7.2.6.21No New Firmware Available
    SatelliteRBS840Family RoomV4.6.14.5No New Firmware Available
    SatelliteRBS840Master BedroomV4.6.14.5No New Firmware Available

     

    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

    It's a frontier Fiber ONT;  Speed tested at that with a laptop is 500/500
    Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended. 

     

    What is the size of your home?

    Sq Ft? Approx 3400


    What is the distance between the router

     

    Router is in the garage.  One sate RBR840 is in family room approx 35feet from the router in the main room we hang out in.  Then a RBR750 is about 35 feet from the router and 35feet from the family room one on the other side of the house; forms like a triangle.  They on second story about 35 feet from the family room there is another RBR840 and a RBR750 about 35 feet from that on other side house.  Nothing is directly above each other.  All are hard wired.

    and satellite(s)

     

    ️? 30 feet or more is recommended in between RBR

     

    and RBS

     

    ️ to begin with depending upon building materials when wired or wirelessly connected.

    All have been disabled before.

     

    Has a power off for 1 minute then back ON with the ISP modem and router and satellites been performed since last update?

     

    Yes


    Be sure to restart your network in this sequence:
    Turn off and unplug modem.
    Turn off router and computers.
    Plug in and turn on modem. Wait 2 minutes for it to connect.
    Turn on the router and wait 2 minutes for it to connect.
    Turn on computers and rest of network.

     

    Has been done prior

     

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

     

    No.  Waiting to have time so family does not kill me with it down too long.

     

    Thank you.

      You need to downgrade the 750 series back to v.4 FW. V4 FW and v7 FW is not compaible between each other. 

      I see NG has not released v7 FW for the 840 series to date either. 

       

      Also for that size of home the router unit and maybe two RBS deployed should be enough. Having 4 RBS deployed may cause problems: https://youtu.be/UR0viMLISz4

      Can you test with both RBS750s turned OFF for now?

       

      If you think you need more then that, try reducing the power on the system on the RBRs web page from 100%  to 25%. Under Advanced Tab/Advanced Settings/Wireless Settings
