RBR750 and 2 RBS750, nightmares, almost non-usable

I purchased 2 RBK752 kits, but currently working with 1 Router and 2 Satellites. 

From day 1 when I first configured it I started to see issues as my iphone had hard time connecting to it - it keeps trying and doesn't get an IP. after some time it gets one.

 

I thought it will be just bootstrap issues, but after 4 months of use I still tackle issues every day.

Sometimes my devices loose WIFI connections although the satellite near them seems OK - not flashing and in the web interface it shows 2 satellites are up-running - but one satellite had 0 devices connected while it's surrounded by 10s of devices trying to connect.

Sometimes even the wired devices loose connection and cannot get IP.

Also worth mentioning that after a reboot of the router or the satellites it take hours, even days, to get all the devices to get connected.

 

I will describe the setup I have, but I'm sure you wanna know more stuff, just let know what is missing and how to get it and I post it.

I'm using RBR750 as a Router, 2 RBS750 connected wired with it, one from same kit, one from other kit. both get synced with the router

Connected to the router is my Modem/Router (DSL-G256DG), which cannot be configured as Modem only or bridge, so currently it's configured as a router as well with one client - the RBR750. (I know this is called double NAT, but configuring it well worked for me with the previous mesh system, so I guess also with Orbi it should work).

 

I have about 40-50 devices, most are IoT, few TVs, smartphones and few laptops.

 

I updated the RBR and RBS with latest FW: 

V7.2.6.21_5.0.20

but I still face these issues.

 

appreciate your help.

    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
    Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended. 

     

    What model iPhone and what version of iOS is on this phone?
    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? 
    Does this happen with both wireless and wired devices? 
    What channel configurations are currently set on the router?  

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

     

    Be sure to disable any MAC Address randomizers on phones and pads while at home:

    Try disabling the following and see:
    Armor, Smart Parental Controls or Circle, Traffic Meter.

     

    Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s). Under Advanced Tab/Advanced Settings/Wireless Settings

       and RBS️ to begin with depending upon building materials when wired or wirelessly connected. I would say wired 10m (it's different floors, but air-distance may be 4-5 meters.

        I tried this:

        Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes

         

        Didn't help much, now my devices are trying to connect without success.

        From the Iphone I can see that it keeps loosing it's IP (gets 169.... instead of 192.168...).. and only after many retries - several minutes or more, it succeed to get it's real IP, but then it looses it again...
