Dear @David-TP,

I have 2xDeco M4 devices setup. I live in a house with few neighbours around. When I want to relax, I play online multiplayer games. Quite often the interference is terrible and I have ourbursts of lagg spikes. And the app confirms there is interference in play. I would like to to be able to manually select channels to see how system performs myself.

On 5ghz frequency (same issue goes for 2,4ghz btw) Deco chooses most used channel 40, that everybody around uses. How? How did you program any sort of channel automation into your system, if it  doesnt do anything and just chooses most blatantly obvious channel my grandpa would pick? After diagnostics the app says everything is setup fine, while its obviously not, because it doesnt go away as it doesnt pick other channels.

I m sorry, but this is just a shame guys. Your product doesnt work as intended (apparently products as I read the thread). You are not working on it for 4 years now, arent you? In fact, engineers probably know it cannot be done because of mesh system nature itself. I understand your explanation you posted 3 years ago, but engineers should have said either "yes we can do it" and then fix it in reasonable amout of time, or "no, it cant be done".

I think I will look elsewhere for my next product. 

But as a last resort: My firmware on M4R is 
1.0.2 Build 20220401
Rel. 35920
and the automatic update system reads it as most up to date. Can the firmware be an issue?

Sorry for appearing a little upset, but I m just dissapointed in such a basic function missing. Thank you for any kind of reply and have a nice day.

@poop12345 a lot of us are upset too.  Being able to manually override channels seems like a basic function that TP-Link could have and should have developed by now.  But I disagree with the "engineers probably know it cannot be done because of mesh system" - I don't see why a mesh system would be locked to certain channels.  With a mesh system, all of the devices within the mesh would need to use the same channel but that channel could be any channel allowed by the governing body for that device.  And from what I can tell other brand products do exactly that.  Can you confirm that is correct @David-TP ?

I recently returned from a weekend away at an airbnb in a crowded vacation area.  They had one wfi router 2 floors away from the bedroom I was in and I found only one weak spot in the house.  That one device managed to work better than my 4 Deco mesh network at home.  And the reason is simple - less channel interference.  It really highlights the poor performance from my Decos and what should be a technologically superior network. 

Could someone from TP-Link please give us an update on when we will have the ability to change 5ghz channels? The function to pick the best channel does not work.

This was promised for 4 years now. I need to know when it will happen or I will move on to a different mesh system. 

Tired of this problem being ignored.

Is anyone from TP-LINK going to update us in the status of this issue? My P9s keep selecting the most congested channels making them unusable.
