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!
