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.

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. https://kb.netgear.com/31029/Where-should-I-place-my-Orbi-satellite 🛰️
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?
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

What model iPhone and what version of iOS is on this phone? iphone 11 pro , IOS 17 What is the size of your home? Sq Ft? I have 3 floors, each is about 1700 Sq feet, I have the router in the middle floor, and two cables connects the 2 satellites in the other floors. What is the distance between the router andsatellite(s)? 30 feet or more is recommended in between RBR
Does this happen with the RBS turned OFF? I didn't check. Does this happen with both wireless and wired devices? yes What channel configurations are currently set on the router?
2.4 GHz Channel
Auto (2)
2.4 GHz Wireless mode:
Up to 573.5 Mbps
5 GHz Channel
36 + 40 + 44 + 48(P)
5 GHz Wireless mode:
Up to 1201 Mbps
Any Wifi Neighbors near by? If so, how many? not so close.
Try disabling the following and see: Armor, Smart Parental Controls or Circle, Traffic Meter. all is off I guess
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 I will try

When I search for DSL-G256DG, I wind up on this D-Link page:

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...
Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
Turn OFF the RBS and just test with the RBR alone for now.
So the RBS are ethernet connected to the RBR? If so, how are they connected, is there a LAN switch or patch panel in between the RBR and RBS? Brand and model of switch if one is in use please.

Use exactly the same WiFi credentials so that WiFi devices will not have to be configured again in order to connect.
It does not appear that Netgear supports Hebrew on this model (on any model?) What language is used for entries? (SSID, passwords, etc.)
As you are aware, a Double NAT can make specific applications difficult to set up, but should have nothing to do with devices connecting to the Orbi LAN and receiving IP assignments. When my Orbi is power cycled, everything is back on line within minutes. Never "hours" or "days".
Re: RBR750 and 2 RBS750, nightmares, almost non-usable
regarding the RBS-RBR connection, I do have at least one LAN switch in-between, it's tp-link TL-SG105E. I'm not sure if there is another one in the way but I can check that tomorrow as well.
Re: RBR750 and 2 RBS750, nightmares, almost non-usable
Tried with RBR only, same issue, took my iphone half an hour to get a stable connection.
Regarding the channel selection, as I replied previously, I did select the channels manually, and I posted the status after reboot (I don't know if any other option is available for choosing the channels).
Any next steps to resolve the issue ?
Should I attach some logs or anything helpful to identify the problem ?
Re: RBR750 and 2 RBS750, nightmares, almost non-usable
What iPhone model do you have?
What iOS is loaded on the iPhone?
Do other iPhones or pads exhibit this problem?
I ran my 750 series last month for a bit. I have a iPhone 12 Pro Max with iOS 16.5 loaded on it. Saw no issues with it connecting. I also have WIFI Private IP Address disabled while I'm at home.
Manual channels 1 and 40 on mine and 40Mhz channel width only as well.
Re: RBR750 and 2 RBS750, nightmares, almost non-usable
What iPhone model do you have? IPhone 11 pro
What iOS is loaded on the iPhone? 17.1.2
Do other iPhones or pads exhibit this problem? yes, and other devices not only Apple, my Lenovo laptop, my LG TV and others.
I just checked if the solution worked on my IPhone and it didn't.
I'm sure this is not a common problem with all setups, as I see this series has high rating. But seems I have a problem in my setup/configuration so I need your help to identify it.
Re: RBR750 and 2 RBS750, nightmares, almost non-usable
Might give this a try.
Bring the RBS to same or near by the RBR. Allow them to wirelessly sync. I would download the v7 FW files for the RBS and RBR to you local PC desktop. Have this PC ethernet connected.
Using a MS Edge or Opera web browser, Log into each RBS web page and send the RBS FW file there to each. As the RBS get the FW update, go head and update the RBR using the RBR file using same process.
Allow the RBS and RBR to process the file. Once the system is back up and running and RBS are synced, power OFF the RBS then RBR for 1 minute then back ON.
After the system is back online and RBS are connected. Turn OFF the RBS for now.
I'd make sure any mac address randomizers are disabled on phones and pads.
Set manual channel 1 or 11 on 2.4Ghz and channel 40 or 48 on 5Ghz on the RBR.
Don't enable any Armor or Traffic Meter features.
Don't connect any LAN switches to the RBR.
Run with the RBR along and test to see if the devices are still not connecting right or problem is still present.
Re: RBR750 and 2 RBS750, nightmares, almost non-usable
I already have the v7 FW loaded on them. Do you think I need to re-burn it or maybe it’s better to factory reset them while on the v7 firmware and set them again one by one?
