I do not have all the options available on my app that are pictured in the User Guide. Especially the 2.4 and 5Ghz band control. Why not?
No I mean I cannot turn off 2.4 ghz or 5 ghz radio signal, but it says I can in the manual. The manual also says I can check bandwidth from the Deco app, but there is no option in the app for it
If you have the Deco M4 the firmware may not be out yet.
If you have the Deco M5 or Deco M9 provide some screenshots so we can see what you are looking at.
