Frustration with RT-BE88U and SmartDevices

[Krism]

I have the impression that the latest FW released by asus (this week) has lots of major changes in opposit if the latest Merlin version which was based on some (very) old GPL.

I think I'm going to give the net asus stock FW a try with a full reset too

So I had the time to play around with the new firmware, but no luck for getting the guest iot to work. None of my devices wanted to connect.
I tried different setups: iot both same subnet and not , custom wifi network both allow intranet access and not.

All iot devices linked within seconds on the primary wifi network. But that is not really what I want
All tested with the latest stock FW and reset settings.

I thing I noticed, guest network doesn't broadcast if you have only 1 wifi band enabled. Thus you need 2.4 & 5Ghz enabled to have it broadcasted

Hopefully someone has ideas to get the IOT seperated?
