What Firmware version is currently loaded?

What is the distance between the router and satellite(s)? 30 feet is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router

 

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?

Try enabling Beamforming and MIMO(MIMO may or maynot be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings

Try disabling the following and see:
Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).

    Other side of the House, one level below (so at least 40ft)

    Any Wifi Neighbors near by? If so, how many?

    Currently Manual on 2.4GHz = 11(P)+ 7(S)

    5G Channel 36+40+44+48(P)

    Lots of wifi neighbors but spread  1-2 per channel (27 different signals detected)

    Try enabling Beamforming and MIMO(MIMO may or maynot be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings
    WMM enabled on both 2.4 and 5 GHz

    Beanforming enabled

    MIMO -> Set to Enabled

    Preamble -> Reset to short on both

    CTS/RTS is 2341 0n 2.4

    CTS/RTS is 2345 on 5

    Has Power at 50% on 2.4 ->100%

     

    No Armor

    No Daisy Chain

    No Fast Roaming

    No IPv6

    No coexistence

     

    Try disabling the following and see:
    Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).


    My Setup (Cable 900Mbps/50Mbps)>CM1100>Orbi RBK50 v2.5.1.16 and Orbi RBK853 v3.2.11.2(AP Mode)

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

      Rebooted.  

      Satellite repositioned and now Blue - (instead of Magenta) - show online on the phone app

      All devices properly connected. 

       

      So far connection status show 13:38 up time. So no apparent drop since reboot. 

       

       

      Also Telnet a different value before for the lease length - 86400 -> 1200

        Just got a impromptu reboot when submitting response. So duration was about 15min.
