Accepted Manual Signal Source Selection on Deco
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.

Hi, I happen to see that you are on firmware 1.4.3.
And the firmware 1.5.2 build 20210916 has added a new feature “network optimization” which would help optimize the signal source selection.
Maybe you could try to update the firmware to have a look.
@Andyl73 For the Deco P9, it is a little bit different from other mesh systems.
Once the powerline backhaul is activated, the signal source of the powerline backhaul is always from the main P9.

Just return them (if possible). It looks this is very well known and the same happened to me with the Deco X68. Without regards of the devices location, they ALWAYS look to connect in a "star" topology, which, evidently does not work for everyone. Then, it is claimed that the system "automatically" selects the best signal, which in my case, is also misleading not only network speed on far devices spoke by themselves, the system was not very stable.
I'm more than willing to "retry" these devices once I hear that those issues are resolved, otherwise, the price tag does not justify the effort.
In the meantime and even though they is not 802.11AX capable, three Google Wifi's (AC2200) are more stable, giving me coverage in places where the three X68's did not and I get around the same network speed (of course, knowing is not possible to manually select the source on the X68s, which may probably be the reason)

@TP-Link Any update on this for the e4 & m4 units? I have 2 M4 units (1 as the router and 1 with a cabled backhaul at the other end of the house) and all the e4 units (3 of them) insist on connecting to the router instead of the closest backhaul unit. This results in slow speeds.

@TP-Link
Any firmware available for S4?
This is extremely disapointing to have to find out that these products do not do what they are advertised as doing.
The reason I purchased these is precisely due to the advertisment of they operating in a 'ranch style house' but they absolutely do not work that way.
Very disapointing. I hope there is some beta firmware available that will allow me to select the source manually to enable the ranch style house configuration.

This is a textbook case of false advertising.
This product does not do "mesh" networking at all.
@tplink I want a full refund for my purchase since the product does not do what it claims to do. I will return my hardware to you. Where should I (we) send it? Thank you.

I am using M9 Plus and updated the latest firmware but there is no option to allow me to manually select the Signal Source. All my statelite nodes are still connected to the main Deco with weak signal rather than the nearest nodes.
Please advise.

Uh oh @TP-Link Australian Consumer Affairs is not a big fan of false advertising where the product is not fit for purpose.
Guess i'll be returning these and lodging a complaint

Thank you for the notification.
Well, I don’t think there is any false advertising.
Deco is capable of both Daisy Chain and Star topologies.
And It will make its decisions depending on the spatial distance, barriers, and current Wi-Fi interference.
So you could see not all users only got star topologies and sometimes Deco will change between Daisy chain and Star topologies for better performance.
But considering that many customers tend to customize the signal source by themselves, we have already planned to add this option on the firmware 1.6.0, such as Deco M5 and other Deco models later.
The latest news I just got from the engineers, the official firmware of 1.6.0 could be expected in Q1 of 2022.
Thank you very much.

@TP-Link I don't believe this is correct, none of my e4 or m4 devices will connect to anything other than the main device, even when the backhaul unit is located in the same room as the client e4/m4.
