Device constantly switching between 2.4 GHz/5GHz

We encountered issues when playing music via Airplay.

The Access point log shows devices (all iOS) which authenticate themselves on the AP every 1-5 minutes. When doing this, they constantly keep switching between 2.4 GHz and 5 GHz.

06.10.22 20:47:28 [fritz.powerline] WLAN-Gerät hat sich neu angemeldet (2,4 GHz), 144 Mbit/s, PC-192-168-178-170, IP 192.168.178.170, MAC 26:16:86:06:8A:0C.

("WLAN-Gerät hat sich neu angemeldet" means "Wifi device has re-authenticated")

I recorded the following traces:

  • WIFI Management frames: https://drive.google.com/file/d/10OFZETH28FTLeytH8JG2UyrBwZ9p8sln/view?usp=sharing
  • 2.4 GHz interface: https://drive.google.com/file/d/1-Zg3UuCGZTjTfgtfpV_kDDgRw1zzJq1Z/view?usp=sharing
  • 5 GHz interface: https://drive.google.com/file/d/1jhU3IuliBqhcpsUKnVD2YUldIu4Fyt9L/view?usp=sharing

I would be happy to find out the following:

  • What keeps triggering the device to constantly re-authenticate and keep switching frequency?
  • Why does this switching behavior only occur when playing music via Airplay?

Background info:

  • All devices are in the same room.
  • The AP is part of a so called "Mesh".
  • The AP (Fritz Powerline 1260e) is connected to the "Mesh Master" (Fritz!Box 7590) via Powerline.

UPDATE

Each time before the client re-authenticates, it receives a Disassociation frame from the AP with one of the following reason codes:

  • Previous authentication no longer valid (0x0002): This is not being sent to other clients. How to interpret this?
  • Disassociated because sending STA is leaving (or has left) BSS (0x0008): The client remained in the same room all the time. Does this indicate a poor radio signal?
