Orbi RBR850 + Orbi RBS850 Limited Connection due to DNS

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.
