Orbi RBR850 + Orbi RBS850 Limited Connection due to DNS

Hi

After a couple of stable days, the issue is back as I expected. See below Windows Log for errors. It is just a short interruption, but anyway anoying when streaming or gaming. Just not good enough. I hope a solution will emerge, rather sooner than later. I will leave this thread open and unclarified for now.

Is IPv6 enabled on the RBR? If not, what happens if you enable it and just Auto settings there? 

I have now activated IPv6 with auto settings, see below. I will wait and see.

Furthermore I have noticed the following - an attempt to auto update router even though I recall you said it should be disabled and another issue but not as important is the NTP time server not setting the correct time. I have attached screenshots below.

An auto-update firmware failed, maybe the cause of the interruption yesterday?

NTP setting.

I will monitor with IPv6 enabled and get back to you.

Hi Again

I have now been monitoring some time, and it seems that IPv6 enablement has reduced the frequency of DNS issues, but I can't be completely sure, because they still occur for my satellite connected units.

I have noticed random reboots happening within a 1-3 day interval of the sattellites, not the router. Furthermore the reboot happens synchronously for the satellites? I have tried disabling one satellite unit to verify if it's wifi congestion/saturation as some threads suggest, but with no luck.

I do not expect hardware issue either as it has been running fine for a long period of time before 2022. I need the cabling setup working with a central switch connecting my units on different floors in the house for better stability and performance.

I am running out of options and patience. This try and error process is draining my batteries! Can anyone confirm if there is a firmware bug on these Orbi units, so I do not have to use my energy on something that doesn't work? I can then accept it and just live with it, until the firmware is fixed.

As previously written, I have a wired backhaul setup through a central switch which connects the router and the satellites.

Please help, thanks!

Has a power off for 1 minute then back ON with the ISP modem and router and RBS been performed?
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 the RBS and wait 2 minutes for it to connect.
Turn on computers and rest of network.

What is the size of your home? Sq Ft?
What is the distance between the router and 📡 satellite(s)?

Try setting a custom NTP server address instead of NG default NTP service. 

You might update the RBS first then RBR to v.2:

You might re-enabled router mode on the modem and use the modems DMZ for the RBR in router mode.

Hi Again

I have done the boot sequence when activitating IPv6, should I do this boot sequence each time I do the slightest changes ? I have not done it, after just reconnecting one satellite.

I live in a 3 storey house based on concrete walls blocking all wireless signals. It is only 125 sqm, so it's not the size, but more the layout and the concrete giving wireless challenges. An Orbi is placed centrally on each floor, starting with the router on the top floor - near the modem, and followingly a satellite on each of the 2 below floors. An avg. distance between Orbi units in direct line is around 3-4 meters, but as mentioned the concrete in this case is a great signal blocker.

I have added a wifi signal distribution overview as seen from my pc on the ground floor for 5 GHz, there is a similar one for 2,4GHz but I can only attach one. For the 2,4GHz the wifi distribution for the backhaul hidden wifi is also shown and as I understand, it is active even though not used in a wired seup.

NTP service is working againg, without me doing anything, so I guess thats fine.

I am not sure about your FW version 2 comment, do you recommend it to be done in my case ? and secondly what is the purpose of restoring the ISP modem from bridge to router mode again and place Orbi router in DMZ? and should it be done as seperate attempt or part of the suggested firmware upgrade as welll?.

I mean it's quite cumbersome to do all these tasks, and is it qualified suggestions or just cross my fingers and hope ?

I will not do anything before you reply again on recommended approach and why.
