Although I have never received help in this forum I will write my problem to be solved or at least to be on the waiting list.
There are thousands of topics on my problem. However, the manufacturer (TP-LINK) is never manages to solve the problem, which I'm sure leaves all its customers disappointed. Topics are marked as "Solved", but actually they are not.
I would ask that if this continues for the second year (waiting for the new firmware), all my routers be replaced with M5 (at the expense of the manufacturer), because it is only model with the solved issue.
Let's look at this simple scenario and imagine the apartment is linear. The M9 Plus #1 is the master and the last router (in bold) is the furthest one:
[M9 Plus #1] --------- Ethernet Cable (it actually doesn't matter) ---------> [M9 Plus #2] ---------- WiFi ---------> [M4R]
And this one:
[M9 Plus #1] --------- Ethernet Cable (it actually doesn't matter) ---------> [M4R] ---------- WiFi ---------> [M9 Plus #2]
And guess what - The last router ALWAYS tries to connect to M9 Plus #1, even if it is out of reach. It NEVER tries to reach the middle one. And starts blinking red. Again... and again... and again.
There is no way to force the last Deco to connect to the nearest one, even if it is 0.5 meters from it! Network optimisation, moving the routers and all of the suggestions in this forum are made.
It seems that the only router that receives updates is M5. It is neither higher class nor more expensive. I do not understand why this is so. The rest are useless!
All the things advertised in the box and in the site are complete lie and Deco is really stupid in choosing to which router to connect. It becames more stupid if Decos are different. So guess what - the promise, they are compitable is a lie too!
And one more thing, the last firmware for my M9 is 1.5.1 Build 20210126 Rel. 59387 - So HAPPY first year without updates - M9 Plus!
You are just a piece plastic with red light. I will use it as night LED ;)
About the Firmware of M4, I can't know it, because it is usually offline, but I am sure it is more than 1 year old.
I insist on a solution to the problem, which continues 2 years with promises and unsolved topics in this forum.
Update: installing the debug firmware not changing the situation.
The M4R is 1 meter distance from the M9 Plus and.. it is trying to connect to the M9 that is 15 meters from it.

Hello, Alexandre.
Thank you very much for you answer.
1) As seen in guide (in the app) and the answer from @TP-Link support via email, they said if I have M9 Plus and M4, a M9 Plus should be the master.
2) I am aware that M4R is dual band. It is strange for me, that even connected with Cat 6 cable between two M9 there is much speed loss. The ISP guarantee 300 Mbps and if you connect near Master M9, the speed is fine.
I expect to have around 300 Mbps at least to the second M9, which is connected by cable. Isn't this a normal expectation?
The purpose of this document and TP-Link reply is to make sure the most powerful Deco unit is the Main Deco, because and especially in the Router mode that unit performs all heavy lifting: content filtering, bandwidth throttling, etc.
That becomes less critical in Access Point mode you are using, because other than blacklist there is not much activity happening on Main Deco during regular WiFi utilization by devices.
Even then, with the change I suggested your Main Deco is still M9 Plus. I suggested swapping Satellite Decos, while Main Deco still stays in the middle of the chain. Try that, you have nothing to lose, but you may get better speeds with that setup on devices connected to wireless Satellite Deco M9.

When it comes to speed tests, many variables could influence an outcome. If your ISP provides 300Mbps, your wired Deco units should be able to deliver that much, most of the time, with proper speed testing environment. You'll find recommendations on how to run speed tests in the Section 2 of the following document: Troubleshooting: Slow Internet Speed with Deco Devices
Still, WiFi is not wired connection, and results could fluctuate wildly. Here is an example of back to back speed tests I ran from the same location on the same smartphone connected to the same wired Deco M9 Plus on otherwise idle home network. My Internet is asymmetrical, gigabit down and 30Mbps up, and this is what I've got:
Occasionally, my Deco M9 Plus speed tests get less than 300Mbps, and top speed I ever got is 635Mbps.
