RBRE960 Sony TV (Android TV OS) intermittent connect and disconnect

[MMillerCA]

Since installing firmware V7.2.6.31_5.0.24 my Sony Bravia XR 55A95L "loops" connecting and disconnecting via WiFi.  It was working fine before the update.  The TV will connect successfully to the base Xfinity router via WiFi 6 but that is not my "home" network.  I have tried recycling the router and the TV.  I have tried using DHCP reserved IP and setting manual IP on the TV.

Can you try turning OFF one RBS? 

Size of home, maybe too much having two RBS deployed.

Also 15 feet is a bit too close between the RBR and the one RBS. 30 feet starting distance. 

Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT
https://kb.netgear.com/30187/How-to-fix-issues-with-Double-NAT
Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router.

How many RBS are deployed? 
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?  

Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.

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

I will answer your questions but first note that my connection to the TV was working fine until the update.  So, I'm not sure how some of your questions are pertinent. But...

How many RBS are deployed? base router and 2 RBS
What is the size of your home? Sq Ft? 2 floors.  about 2300 Sq Ft.  Base is essentially placed middle of top (main) floor.  One BRS is in middle of lower floor.  One is in the garage (same level as top floor).
What is the distance between the router 

 and satellite(s)

️? 30 feet or more is recommended in between RBR 

 and RBS 

The garage RBS is about 35 feet from RBR.  The lower floor RBR is about 15 feet.

The TV is about 13 ft from the RBR  with only one wall between them.  When the TV connects it connects to the RBR and never attempts to connect either of the RBS units.

️ to begin with depending upon building materials when wired or wirelessly connected.

Does this happen with the RBS turned OFF? I have not tried this.  Why would this have effected the connection when the firmware was upgraded?
Does this happen with both wireless and wired devices?  The Sony TV is the only effected device.  All other wired or wireless devices are working fine.
What channel configurations are currently set on the router?  

Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update? No, but note from original post that the TV connects to the base Xfinity router(and modem) without issue. 
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.

Has a factory reset and setup from scratch been performed since last FW update? No.  But as note previously I have done a power off and on sequence.

A more detailed description of this "looping" behavior would be useful.

• How long does a typical "loop" take?  (seconds? minutes?)
• Does the TV display any messages during the process?
• Does the TV ever appear on the Orbi list of attached devices? (even briefly)

Is Access Control enabled on this router?  If so, does the TV appear in one of the three lists of devices?
(connected, Allowed but not connected, Blocked but not connected)  If the 2nd and 3rd tables are very long and filled with devices which are no longer likely to connect (visitors, family, devices which have 'gone away') it might be useful to delete them and reduce the size of the tables.

Your intuition is correct that a Factory Reset of the system is not supposed to be required when updating firmware versions.  In this particular case, obviously "something has gone wrong".  If relatively little has been done to customize the system, then a Factory Reset has the potential of giving the system a "clean slate" at the cost of a small amount of effort.  On the other hand, if hours have been spent inputting definitions, setting up parameters, etc. then it is possible to do a "Quick Factory Reset":

• Save a copy of the router configuration to a computer using the Administrative menu item, Backup Settings
• Follow the usual steps to Factory Reset until the router reboots
  https://kb.netgear.com/31486/How-do-I-reset-my-Orbi-system-to-factory-default-settings 
• Use a computer/laptop connected to the router to open the web interface. (Ethernet connection is the easiest, but alas newer laptops are leaving out the Ethernet port)
• Follow the configuration process but....
  • Do not change the WiFi credentials
  • Do not accept the offer to register the router, enable Armor, enable Smart Parental Controls, etc.
• When you reach the page that offers choices: continue configuring manually or load a saved configuration,
  pick the option to load a saved configuration
• Browse to that saved configuration file and upload it.
• The router will automatically reboot and all saved settings will be restored.  The hope is that whatever 'gunk' (technical computer term) was responsible for the problem will no longer be in memory.

I can do this process in under 15 minutes.

The TV connects and disconnects about every 15 seconds.  Here is a screen print of a section of the log showing the process (TV IP address is 192.168.1.25)

When on the TV's network status page it does show the network disconnect and reconnects happening.  

I did turn off the RBS that was downstairs and closest to the router and TV.  I still got the same error process.

Can you downgrade the system to v.21 FW, RBS first, the RBR lastly:

Yes, I did know better that I should not have had two routers working but since Xfinity was working this way I didn't bother with setting up bridge mode and it had a minor advantage I won't go into.  But, I decided you were probably correct and I switch the Xfinity gateway to bridge mode.  That fixed the TV issue.  I think I also know why it was working before.  I think there may have also been an update to the TV firmware.  I dug deeper and have a reasonable explanation for why it caused the issue.  Anyway it works now.  Now I only need to deal with the minor issues caused in my network setup where I was taking advantage of the extra WiFi router.  Thanks for everybodies expert help.

Glad you got it working. Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
