Extremely unstable network with Deco M4

Backstory:
I had three Deco M4 V1 units for a couple of years they were working fine with firmware 1.5.2, when once I upgraded to 1.5.5 or 1.5.6 they became unstable to the point of being useless, a firmware rollback to 1.5.2 fixed the issue, this was around 2022-05-09.
Now around 2 and a half weeks ago I added two more M4 Deco (V4) to the network now the funny thing is that it all did work fine for 2 weeks (the return period of the seller lol),
after 2 weeks it all went downhill:
- wifi randomly stops working or wifi loses internet connection, restarting the main unit fixes this issue for some time
- wired connection sometimes drops too, waiting for a couple of minutes seems to fix this issue but it comes back randomly
What I did so far:
- I upgraded all decos both V1 and V4 to the newest firmware
- I deleted and recreated the network from scratch and I also did a factory reset on all V1 decos while doing this
Network looks like this:
V1 main deco connects to two V1 decos wirelessly
The main deco connects via ethernet to one V4 deco
This one V4 deco which receives the connection via a cable connects to the second V4 deco via wifi
Hi, disconnecting satellite units is just used to simplify the network topology and narrow down the problem. It would not be a permanent solution.
If the two Ethernet-connected Deco M4s could maintain a stable connection, only the wireless Backhaul Deco M4s turned to flash red and disconnected a lot. We could mainly focus on the Wireless Backhaul stability to see whether they are caused by the location or wireless interference around or Deco themselves.
"all satelite decos go red", Did it happen randomly to different Deco at different times, or to all satellite Deco units at the same time?
Except for the following layout, can I have a detailed floor map that indicates the location of each Deco?
Please also check the signal source on the wireless connected Decos to make sure the signal source is at least 2 bars.
Thank you very much.
Best regards.
