ZenWiFi AXE6600 (ET8) - 6 GHz band is not shown on my laptop.

[Karbi]

I have ZenWiFi AXE6600 (ET8) router. I use ethernet for backhaul.  But the 6GHz band is not shown on my laptop.

2.4 GHz and 5GHz SSIDs are shown, but 6GHz SSiD is not shown in available networks in my Win 11 laptop.

Is there any setting I need to change in the router so that 6 GHz is shown on my laptop?

Please help.

What I observed is that...6GHz band is showing up only when all the nodes are on/online.

When the nodes are switched off (the main router is on), then the 6GHz band is not showing up.

How to make the 6GHz band to show up, irrespective of whether the nodes are on or off?

I suggest you try enabling Ethernet Backhaul Mode.  Please see and follow this article depending on exactly how they are connected:

I have been using Ethernet Backhaul mode since the beginning. 

My setup is exactly the same as given in the link you provided.
