Security Cameras and 2.4Ghz only network
Security cameras usually require 2.4 GHz network. If the network automatically chooses either 2.4 or 5ghz, then the security cameras do not work. Allow users to create a dedicated 2.4 GHz Wi-Fi network strictly for security cameras and other devices that require 2.4 GHz only. I am not able to use my security cameras because the system will automatically choose whether I am on 2.4 or 5 GHz.
as another example, I had to disable 5 GHz (entirely; the only option, currently...) in order to setup my new smart doorbell. It only supported 2.4 GHz.
Afterwards I was able to re-enable the typical dual-band and the doorbell continued to work. But it would have been great if I could assigned that one device to 2.4-only.
