RB750 Orbi satellites constantly calling new DHCP addresses

I have a 4 satellite mesh set up with 750's and we constantly get connectivity issues with signal dropping out. Fibre connection to hub is fine (have a camera pointed at it to check lights etc as Orbi logs give  so little detail!) and coverage it good as is the mesh network. When I do look at the logs it seems each satellite to calling for new DHCP assignments every few  seconds/minutes (roughly 150 from each satellite in 18 hours) - is this normal ? Any idea why ? ITs not the attached devices but the satellites them selves - example below

    What is the Device at .1.55 IP address?

     

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

     

    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 wired or wirelessly connected.

    Does this happen with the RBS turned OFF? 
    What channel configurations are currently set on the router?  

     

    Are RBS wireless or ethernet connected to the RBR?

      What is the Device at .1.55 IP address? Its one of my satellites but have the same log for all 4 of them

       

      What Firmware version is currently loaded? All firmware up to date - V7.2.6.31


      What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Swish Fiber but no external make/model (had no issues with pervious versions of orbi setup)

       

      What is the size of your home? Sq Ft? `Approx 2400 but this includes a detached annex which also has satellite.
      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 wired or wirelessly connected.
      https://kb.netgear.com/31029/Where-should-I-place-my-Orbi-satellite ‌‌

      On average somewhere around 30 ft depending on walls etc - have done a walk round and mapped using Ekahau

       

      Does this happen with the RBS turned OFF? I would assume not as all the large logs (100+ / 12-24  hours)  are generated by the satellites themselves and not by the devices

       

      What channel configurations are currently set on the router?   Both on auto and does not look like any interference from neighbours.

       

      Are RBS wireless or ethernet connected to the RBR? All wireless with about 50 devices attached - all but one are wireless

        I can see one reason, 2400sq ft home with 3 RBS along with the RBR, maybe having too much RBS in a small home is probably causing the RBS to loose connection temporarily or ping pong around as the RBS maybe trying to re-sync to the RBR or each other and this would cause seeing the DHCP log being flooded. 

         

        Can you turn OFF all but one RBS in the home. Then observe the logging. 

         

        How far this this annex from the main home building? 

         

        Did you update the system, RBS first then RBR lastly? 

        Has a factory reset been performed since you updated? 

         

        Seeing some users post that v.31 has been causing other problems for there systems. You might want to downgrade to v.21 as one additional step in this.
