Method to set different SSID on 2.4 ghz and 5 ghz

But why do you want to have different ssid?

This call steering bandwidth.You can disable this in router setting.

Have a look at this:

If it helps, thanks for kudo~

This function I will prefer to leave it on, this feature encourages the client to connect to the less crowded 5GHz network.

You need to go in the fizz wifi app and disable band steering.

Why I want to do this: prevent re-configuring 5 different devices in the house that only work on 2.4 Ghz and that was how my previous router was configured. So saves time.
Thanks for all the help!
