Deco M5 - Middle one is the slowest

Hi!
I have three Deco M5's in my house. One is attached (by cable) to my router, in the stairwell on the first floor.
The second is connected wirelessly, straight above the first one, also in the stairwell but on the second floor.
The third is connected wirelessly too, straight above the second one, also in the stairwell but on the third flow.
The distance between the Deco M5's are about 2,5-3 meters.
The first one, on the first floor, works great: it reaches the maximum speed of 200 Mbps.
The second one, on the second floor, works not so good: it reaches a speed of about 50 Mbps.
The third one, one the third floor, works great too: it reaches speeds of 150 Mbps.
I don't understand how the Deco on the first and third floor work great, but the one in the middle does not. I have tried resetting or reinstalling the Deco's and made sure that they are installed in the correct order, but the speeds remain the same. All three devices stand fully free and have no other electrical devices around them.
Does anyone have an idea of why the middle one can be slower than the other two? The one on the third floor is much further away from the cabled Deco M5 that is connected by cable, but still works a lot better than the one on the second floor.
Thank you in advance!
Have you checked to which Deco each of Decos is connected, and what is signal strength of their connections? If I to guess, one of the possibilities could be Deco on the second floor is connected to the Deco on the third floor instead of to Main Deco.
You can find the info to which Deco current Deco is connected and with what signal quality in Deco app. Here is an example from my Satellite Deco M5 connected wirelessly to Main Deco in the living room, and I named Main Deco "Living Room."
You should check Signal Source on both second and third floor Decos.
Also, and sorry if it sounds if I am trying to insult your intelligence, it is not so: even smart people occasinally make silly mistakes. Are you sure your mobile device you run speed tests on is connected to the Deco on the right floor, and are you sure that you have named Decos properly according to their placement? For example, if you named Deco "Second Floor" but placed it on the third floor, and Deco named "Third floor" is actually located on the second floor - that would explain this puzzle.
What I would suggest is to power off Deco which is on the third floor and see: A) Which Decos left online according to Deco app and B) if second floor Deco suddenly shows better speed test results.
That one test will address all of the above possibilities.
