@TP-Link @TP-Link_Deco 

you keep saying since 2019 that you would solve the issue / engineers are working on this / just wait for updates...

we spent money in your products expecting a mesh system.

we got a good wifi extender paying the mesh system price.

we came to this forum asking for help and received only "wait, wait and wait again". We cannot even ask for a refund since most of us bought the system months ago already.

we now wait for an update to solve this issue. 

I think we are not asking for anything special - we just want a mesh system to work like a mesh system should work.

I wonder how many folks with the problem bought their Deco from Amazon and gave it an appropriately reduced rating with comments. If enough people did that, maybe Tp-link would take some action.

I gave it only three stars, both for the problem in the thread and the inadequate customer support in solving it.

There are many 4 and 5 star reviews. In a simple setup, it probably works fine for those users. Or the users have such fast internet connections that they don't even realize the wifi could be much better. Probably very few understand the issue here at all.

@RandySea2 
I got mine set up yesterday. I was initially impressed with the set up ease........and then I noticed what everyone else has noticed.
Emperor's new clothes.
The ludicrous situation I have is this......I stand next to the Deco in my office and run a speed test. However my laptop is actually connected to a downstairs Deco much further away.
So I force the laptop to use the Deco in the office that I am standing next to and repeat the speed test. I get a slower speed!
This effectively makes the 3rd Deco in my set up useless - it is adding NOTHING as I am getting a better signal from a Deco much further away.

This is not a true mesh system. TP-Link are on very dodgy ground claiming it is. 

I will be returning it as it has not significantly improved the WiFi in my house that I was getting from an Apple Time Capsule, extending with an Airport Express,

Same issue here with a Deco M9 Plus tri-pack. This doesn't make sense at all? I've got 3 levels: living room ground floor, bedroom, attic. I've installed in order from bottom to top.  Now the attic has a dodgy connection to the ground-floor, and the bedroom is connecting to the attic????? This is all backwards....

Any suggestions how to solve this? Otherwise i need to return it i'm afraid. Forcing the connection source would solve the issue quickly.

@MackPhoenix62 Is ANYONE going to respond to this? JD Power Customer Satisfaction Award what???

i am having the same issue here....it like the deco m5  on 1st floor always connect to the deco m5  third floor ..and i do have deco m5 on my 2nd floor..it suppose connect on the 2nd floor since it the nearest one. just dont understand why it connect to the farthest one! .. tplink need to fix this..yes it frustrate when the math dont do it right.

@xdynastyboyx 

Guys please note that Tp-Link will not respond to such comments and requests. We have tortured them enough for a long time. They just have a repeated response of engineers working on it. 

Actually the fact of the matter is that the engineers at tplink are duffers. They don't know how to fix the issues. Numerous requests have been made to them to sort out the channel change and similar requests but they have failed miserably. 

I am sorry to say but we all have been cheated by this Chinese bugger. 

Ditch it and go for Orbi or velop. 

We all have learned it the hard way. 😔

I've also got the same problems with the M5 units not linking correctly.

Also would like the ability to set devices to only connect to specific M5 units. I know you can turn mesh off for devices and that helps a bit, but it doesn't seem to guarantee that the device will always connect to the same M5 unit after power cycling. 

Can TP-Link please allow users more control over their systems, as the automated way the M5 system works at present doesn't work as well in the real world as it probably appears to in the test environment.
