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, for your case, it is more related to the roaming protocol on these mobile devices.
The following link would provide some guidance:
Why my clients don't roam/connect to the nearest Deco node?
At the same time, it is suggested to turn off the Mesh Technology on these devices and reboot them to have a look.

@TP-Link I've updated my M5 decos to the 1.6.0 firmware but am still unable to manually specify the signal source selection via the ios or android apps. I have an ethernet backhaul, but the secondary deco is still using the main deco as the signal source.

Hi, thank you for your patience.
Did you mean there is no option to edit the signal source, or you have already changed the signal source, but it did not take effect?
If it is the second case, would rebooting this Deco make any difference after changing the signal source?
As for the second issue about Ethernet backhaul, did you mean the Deco that is supposed to be on Ethernet backhaul, still displayed wireless backhaul on the APP?
If yes, Did the Ethernet backhaul work before the 1.6.0 upgrade?
Thank you very much and wait for your reply.

@TP-Link my issue was with the network layout. After I reconfigured my layout to have the following structure, the ethernet backhaul was automatically enabled (decos are in AP mode):
internet -> modem -> router -> switch -> deco 1 / deco 2
I previously had the following structure which would not work in AP mode (or router mode) with ethernet backhaul:
internet -> modem -> switch -> router -> deco 1 / deco 2
However, the deco app still does not allow for changing the signal source (I thought based on reading, that with firmware version 1.6.0, it was possible to manually specify the signal source from the app, but when I tap the "signal source" in the app, nothing happens).

Hi, Could you please go to Deco APP>three lines on the top>help>contact us>suggestions and add the APP log, then send the feedback to us?
By the way, is there any chance that you could record a video clip when you tried to change the signal source, but nothing happened?
In case there is any misunderstanding, the signal source here only refers to which Deco nodes, like you could choose Deco 1 or Deco 2 as the signal source of Deco 3, but you could not choose wireless backhaul or Ethernet backhaul to Deco 1.

hi Tp link
having the same issue with my M4 on firmware 1.5.2. Is there yet an update so the signal source can be selected or at least the furthest away deco connects to the closest (daisy chain) rather than the hub? I have seen some other posts that this could be possible. Please can you advise
thank you.

I managed to get them to connect in a chain by rebooting the main deco, which forced the further away deco to connect to the middle one while the main deco was down. It doesn't work every time though, sometimes it takes many reboots, and most of the time the further away deco's revert to connecting to the main one after boot is complete anyway. Mine have been fine for almost a week now though, 4 M4's all chained. Hopefully the new firmware will be out soon so I can make that permanent...

@TP-Link Having the same issue of distant deco keeps connecting to the wrong unit. Hopefully you will release a fix soon to allow choosing the signal source manually, as this is really frustrating.

@AlonK Same here, it seems there is no currently solution if you are using something different than M5.
But they have "top request" since 2 years about that.
