@TP-Link Doesnt work on M9 plus.

the update is shitt!!!!!!!!!!!

All decos keep getting connected to main deco, the logic that has been used to connect is total crap!! Waste of money, its so costly, all in vain.

I have got 200 mbps connection, and i m getting 45 mbps.. Shitt Link, instead of TP Link

@TP-Link I have V3.0 of the X60s, is there a specific beta firmware for them?

@TP-Link 

I was aiming for Whole Home Wi-Fi, I have a total of 6 Deco (M9 Plus) units to do so. 

I have disabled 2.4 GHz band, as I do not want any devices to remain connected to a slower speed.

I have 200 Mbps connection upload & download

I have mentioned the speed I'm getting in my connected device in each room in the below picture

I have mentioned the connection details  - which deco is currently connected to which Deco, that too I achieved by restarting 2 or more deco units multiple times 

The placement (height) of the Deco Unit in the below picture resembles the actual position of the Deco Unit in the room in reality

I have mentioned the room sizes as well

i have attached the Deco Layout as well

@TP-Link 

Is there any beta available for the M4 so that we may test and report back? Thanks.

@TP-Link 

Well, in my case I have three "brand new" never registered, or used Deco X68 and am having the same issue. Installed as instructed, updated firmware, rebooted, removed from the mesh, rejoined them, you name it.

I ended up opening a ticket with TP-LINK support directly. Extremely disappointed with the units as I had high expectations. One of the key factors that made me decide on the Deco units is the capability to expand your "mesh" network by adding other Deco devices.

Evidently, this is not the case. You can expand your WiFi but it will not have the "mesh"capability" which is really the main purpose. For the X68 I have no way to select the device for the "satellite" to connect to (source). And, even though it may be an "intelligent" decision, it does not look like that. For me, this is an actual deal breaker.

I was looking to upgrade from Google AC WiFi mesh network and found myself with more dead spots in the basement due to that. Not good.

When you say "Deco will choose the best signal source by itself", is there a way for me to see the quality of the signal each device gets from the source? 

As of right now, the only signal quality seen is the one to the "source" which cannot be changed or even tested with others.

So, in my case, it is impossible due to the location of each of the three devices. Three floors, main located in the third upper floor, and one satellite on each lower floors (Second floor and Basement), pretty much located in opposite sides of the house.

Then, what really does not make sense is that, from the Basement device, there is an "almost direct" line of sight to the second floor device. and then main device located in the third floor, almost opposite side of the house. 

Really hope it can be resolved very soon. I like the units but they clearly do not work as a mesh network and more as a WiFi extender which, don't work for me specially after the price tag on the kit. I'll have no other choice than to return them and go with another brand.
