What is the size of your home? Sq Ft?
What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between RBR and RBS📡 to begin with depending upon building materials when wirelessly connected.
Also try turning down the power output of the RBRs wifi radios from 100% to 50% and see if this changes anything. Under Advanced Tab/Advanced Settings/Wireless Settings would help for wifi congested areas.

The wireless router to satellites are about ~43 feet apart with power settings at 50%.  My other wireless AP is about the same distance at different locations on 5 GHz, 80 MHz, so there is no overlapping.  Even with lower power settings, it does not negate my neighbors' broadcast strength and configurations for interference.  The AP's are hardwired to the main router.  Something to consider, is trying 25% power with the option for 20/40 MHz enabled, but I don't  think it would work as I can see 7 other wireless routers from my home.

    So you have two wifi systems running at the same time? 

     

    What FW version do you have loaded on the Orbi system? 

    What channels are you using one each system?

      Yes, I have 2 AP's running on two separate vlans.  I'm running on the latest available firmware, V4.6.8.2_2.1.9 on the Orbi.  The other AP is running strictly on 5 GHz band using 80 MHz bandwidth.  I've been stable on the router for over 10 days now with 20/40 coexistence disabled, but stability does come at a cost of speed on 20 MHz.  Just for kicks I've enabling 20/40 coexist at 25% power on the 2.4 GHz band & 50% power on the 5 GHz band.  The Orbi does not have any available options for the bandwidth for 5 GHz.
