Background:    

Some users might notice that all satellite Deco units are connected to the main Deco, instead of the nearest satellite Deco.

 

 

Typical Layout:

 


 

 

Why does the satellite Deco still keep selecting the main Deco as a signal source instead of the nearest satellite Deco?
Deco will choose the best signal source by itself. The selection does not depend absolutely on the signal strength, but also on the connection rate.  Sometimes satellite Deco units may get slower speed due to half-duplex mode and interferences caused by connected devices like phones, or other devices.  To ensure the satellite Deco gets reliable speed, the main Deco stays selected by Satellite Deco after comparative analysis. 


Some users tested that after moving one of the satellites far enough and not being able to reach the main Deco, they finally get the desired connection map:

However, the speed of the satellite becomes slower than what it could get when connecting to the main Deco directly.  Due to the working pattern and protocol/regulation of Wi-Fi technology, the more wireless hops, the slower the speed would be. This rule applies to any kind of mesh or extender system. So it is not always good to connect to the nearest Deco unit.

 

Solutions
TP-Link has planned to give an opportunity for our user to manually select the source Deco as well as improving the current selection mechanism, to better adapt to the various user environments. You may keep an eye on firmware upgrades.

 

Before the official release of this firmware, the current workaround would be:
For Deco M5, there has been a firmware 1.6.0 for trial:

[New Firmware] Deco M5 1.6.0
For other models, please install the following firmware to monitor if the satellite will connect to the nearest node:

Deco M9 Plus V1 1.5.0 build 20210205

Deco M9 Plus V2 1.5.0 build 20210205

Deco X60 V1 1.5.0 build 20210205

Deco X60 V2 1.5.0 build 20210205

Note: Please be sure you have read The Beta Test Agreement before proceeding!

Update: 

If you are experiencing a performance issue which might be brought by the “inappropriate signal source”, please email to support.forum@tp-link.com with the following information:

1. The detailed explaination about your current network proformance issue.

2. A picture of your detailed network layout about the location and distance of each Deco units like the topology mentioned into the OP.

3. A screenshot of the signal source on the satellite unit with the "inappropraite signal source‘.

 

A further notice*:If no performance issues have been noticed, the current selected Deco is actually indeed the best signal source since the distance is not the only factor which decided the signal source, the position of the satellite units and the barriers around all needs to be concerned.

 

Thank you very much.

@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 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

@Tenzin22 Thank you very much for the feedback.

It is suggested to have a look at this link and we have already planned to allow Deco to manually select the signal source.

Did you have any issue with the Deco M9 plus when the satellite unit is not connected to the nearest Deco?
