Not able to deactivate 50GHz band on Deco X20 mesh network
A while ago (probably several firmware updates ago) I was able to temporary deactive 5GHz as this is requried for adding smart home devices. But now I am not able to do this as the system automatically select both 2.4 and 5. I also discovered that I am no longer able to add Guest network. I can do the changes in the app, but when I do a restart of my system it all goes back to no guest network and both 2.4 and 5 bands.
I have 6 units in my setup, 3 units is hardware version 1.0 and 3 units are hardware version 1.2. All have the latest firmware version (1.2.3 Build 20230906 Rel. 41655 and 1.5.2 Build 20230908 Rel. 33060).
