GT-AX11000 & RT-AX92U 5GHz-1 Channel Issue

[ChrisB3127]

First time posting, but have read this board often! It's a wealth of information and very helpful.

I have a GT-AX11000 (primary), and 2 RT-AX92Us. The AX11000 is the primary running in AP mode, and the AX92Us are spread out with ethernet backhaul configured. They are running the beta firmware (9.0.0.4.386_41157), but initially were setup with the latest public firmware, same issue experienced on both firmware.

My problem is 5GHz-1. On the AX11000, I can set the channel to anything above 36 and it sets it correctly (confirmed via Wifi Analyzer app)

However, the 2 nodes never move off of 36. I even went as far as testing all channels, and the nodes stay on 36 regardless.

Changing 2.4 & 5GHz-2 channels do move accordingly, but 5GHz-1 will not.

The wireless logs do not show any DFS issues.

Any suggestions on what could be happening?

Yes, that was the case even on first AiMesh.
A node 5GHz radio will follow second 5GHz radio of a 3 band node. That if node is 2 band model. A 3 band model node will follow both 5GHz channels.
I know it's not intuitive! In AiMesh 1 the second 5GHz radio could not be even a part of SmartConnect, so there wasceven less optimal than in AiMesh 2.
I think I asked the question some time ago, but I believe it got lost in another context (long story here...).
Fast roaming do takes place so it's not a real annoyance for me.

Feel free to open a ticket and ask that specific question. Maybe you will receive an explanation worth sharing.
