Cannot split bands

I am trying to set up my new Xfinity wifi - I have a Gateway XB8. I have MANY home devices that need a 2.4 ghz band. I've been looking online for > 1 hour for how to do this, but nothing works. The admin webpage (10.0.01) says I need to go to the app, so this webpage seems disabled at least for new gateways. On the app, I go to "wifi equipment" then "advanced settings" as directed on other websites, but there is no option to split the bands (as some websites say). When I go to "WiFi details" then "Edit Wifi Settings" there is no option to split the bands to 2.4, 5, and 6 - as other websites say. I think I need to specifically have a 2.4 ghz band for the MANY devices (plugs, lights, fans, etc...) that require it. Can anyone help? I'm at a loss.

They recently updated the gateway's firmware. You have to turn on admin access in the app now;


https://www.xfinity.com/support/articles/admin-tool-access It needs to have firmware version 5.62


Open the Xfinity App. (You'll need a working connection for this step).

Go to the WiFi tab.

Select View WiFi equipment and open Advanced Settings.

Select Admin Tool online access.

Slide the toggle button to Allow Admin Tool access (ON).

Select Save.
