Solved ZenWifi XT9 got disconnected from AiMesh randomly, any help?

[wonderiuy]

Hy everyone,
i have a GT-AX6000 as main router with firmware 3.0.0.4.388.22068 and a (recently purchased) ZenWifi XT9 as AiMesh node on 3.0.0.4.388.22068
From first moment of XT9 usage it often got disconnected form AiMesh, randomly, no specific time or operation.
Before XT9 i had a RT-AC86U wich worked flawlessly.

On XT9 i've tried (re-adding as a mesh node each time):
- resetting to factory def, reflashing 3.0.0.4.388.22068
Still disconnections
- flashing previous version 3.0.0.4.388.21963, resetting
Still disconnections (but less)
- reflashing 3.0.0.4.388.22068, reset to factory def
Still disconnections
- flashed Merlin 388.1 on GT-AX6000
Still disconnection
- flashed back GT-AX6000 to 3.0.0.4.388.22068
Still disconnection

The log on my GT-AX6000 says:

Where A0:36:BC:468:31 is the MAC of the ZenWiFi XT9

Edit:
Forgot to say: backhaul is wired LAN
GT-AX6000 is connected with link aggregation (port 1 and 2) to the switch and the XT9 is connected to that switch (HP 1920S), but this was not a problem when the node was the RT-AC86U

I've tried also to disable "Private Fi-Fi Address" from my iphone (a possible cause) but disconnection still occurs
Do you have any suggestion? Is my XT9 Faulty?
Thank you for any advice

Nodes are having issues with at least the last two firmwares. 22068 and the one before. There is a XT8 thread here where some people are keeping the main rounder on 22068 and the nodes on an older version. That seems to be working.

 

[wonderiuy]

Thank you, so new hardware carries old problems
XT9 has different version numbering than XT8 for the last year, i will give a try with 3.0.0.4.388.21069 and report in a few days

 

[wonderiuy]

Just to confirm: with 3.0.0.4.388.21069 the XT9 is perferct, no more disconnections from AiMesh
