I only have one Lifx product and it's been fine. I'm also using Adaptive QoS.I've been banging my head against a wall for the last week with this - LIFX bulbs keep disconnecting on my new RT-AX82U, they were all fine on my old R7000.
Turning off Adaptive QoS seems to have finally got it stable and working over the last 48h. I'm going to experiment with turning it back on and giving the bulbs a higher priority and report back.
Segregation has worked for me too. Turning off QoS on my AX-82U improved the situation, but I was still having a few of my 9 LIFX bulbs disconnect intermittently, as well as a few other IoT devices like my washing machine.I'm using a Asus AX 58U amd 2 AC88s on a mesh configration...Kept my AX58 at 5Ghz and limited my 2 AC88s to 2.4Ghz.
My Google home devices [about 10 of them on 2.4Ghz.}. Seems to work well since the segregation.
