The answer is: not yet, for Deco X50. TP-Link gradually releases firmware for different Deco models with that feature.

If you like Deco X50, consider replacing it with similar Deco X55, for which beta firmware is available: Deco X55 1.1.0  You will only need to install that firmware on last Deco, opposite to Main Deco. Other two can run as is.

What you need is feature #2 in the list of features: "Added support for customizing Satellite Deco Signal Source under Deco App > Internet > Select the Satellite Deco > Signal Source."

  @Alexandre.  Many thanks for the quick reply. That's sad to hear. Then I probably need to return the set for now and stay at my current config, which also isn't ideal but better what the Deco's offer. Even speed an ping is better with my old kit. I just wanted to replace it with the 3 unit set, to have a more stable network all over my house, as the current one only has 2 units. 

But thanks anyway. Need to find another solutiuon then.

Just in case you haven't returned your X50 set yet, see check: https://community.tp-link.com/en/home/forum/topic/584954

  @Alexandre. Many thanks for bringing to my attention and having this in mind. Appreciate this! Unfortunately I already returned the kit.

Thanks

Hi, i have just noticed that there's this option in the menu, that we can change the preferences. So I decided to delete my former post, I don't want to confuse others... and I am sorry for the wrong terminology, obviously I ment main unit and not satellite. Thsnk you for the correction.
