@darkyto The issue is now even worse.. The secondary decos are loosing connection and dropping on a regular basis.
Here are some of the logs that I've extracted:

I have used QoS to set my Desktop as the only priority device - I have also used my IPS bandwidth speeds. Still, I am noticing that from time to time the connection simply drops even when all other devices are turned off (no smartphones, no Alexa, no laptop, no PS4, nothing active apart from the Decos and the desktop PC).
I've also noticed that if I turn on WiFi on some smartphones then the Decos are immediately disconnected - for example, this happens when my wife uses WiFi on her Samsung A3. Turning of the WiFi on the smartphones improves the situation a bit but still.. this is a no go and the Decos are still dropping.
Anyone from the support here? I am accepting any ideas on how to improve the situation - the Deco mesh system was bought just a month ago and used to work perfectly until recently.
