From your screenshot, both Satellite Deco have good connection to Main Deco. Mind you, even if you manage to have the way you want: Living room - Bedroom - Main Bedroom, WiFi speed in Main Bedroom will be half or less of Bedroom. Every WiFi mesh hop cuts WiFi speeds by half (or more).

I suggest you run speed tests using device connected to Bedroom Deco and then to Main Bedroom Deco. If Main Bedroom Deco delivers WiFi speeds similar to Bedroom Deco, you have optimal configuration.

Thank you for your answer and time. I did speed test in both rooms and speed in Main Bedroom which is connected to Living room is 35% worse than in Bedroom (reminder they are in line Living room- Bedroom - Main bedroom ). I mean I can live with that its just the fact that these things annoy me. Some apps have this connection preference and its so easy to do that. I should be entitled to change the way my network works am I right? I am aware that S7 is on lower end on the devices they sell but its still 200 euros...
