all clients disconnect and reconnect across network of multiple TP Link devices
all clients disconnect and reconnect across network of multiple TP Link devices
Every client connected to my network is disconnecting and reconnecting from the network and I am looking for some help to debug whether this is a product bug or a misconfiguration.
I've updated every switch and WAP firmware and rebooted all of them, but the problem persists.
Any advice on what to do?
Not shown in the diagram, I have a 2 port LAG between brain and switch-core and a 2 port LAG between switch-core and switch-poe on the fibre ports.

@BubbaBubba Check for any rogue devices, scan for malware, check for incorrect cables, and also check the wireless settings.

I have done as the commenters' suggested. I've removed much of the complexity from the problem. I've removed most of the devices from the configuration, removed all bonding, all Linux bridges and probably other removals.
This is my simplified configuration and current problem.
Linux Router / Omada Controller (brain) <----> switch-10 <----> switch-poe
Omada/Switches:
Linux Router:

The interfaces are not on a Linux Bridge, so I don't think there's any routing happening between networks LAN and IOT.
However, Omada/switches have brain listed with a 192.168.1.1 (LAN) address, but on the Security network.
switch-10 port #8 has profile All.
I have been experiencing link down/up on brain when I make the configuration more complicated, but I wanted to resolve this before I started building back up the complexity.

As you can see the switches/omada logs are showing 'brain' being moved back and forth from my IOT network and LAN network.
