Hi,

Should I use Dual-Band Radios on my Cisco 9120 setup?

It was enabled through setup but if I want to disable it, how do I do this?

You can disable by going Configuration --> Wireless--Access point - select which one you want to disable.

 - In standard deployments 2.4Ghz and 5Ghz are enabled because of client  needs (being older clients or not) , why do you want to disable it ?

I want to disable it to test something in my wifi setup.

You can control the function of dual band radios using the flexible radio assignment (FRA) feature whereby the controller changes the first radio from 2.4GHZ to 5GHz operation or simply turns it off, automatically.

You can disable a specific band on any WLAN:

And you can turn off a specific radio on an AP (change Admin Status):

Same for 2.4GHz

Generally speaking you should leave 2.4GHz enabled unless you are 100% sure that all your clients can work on 5GHz.  Some older and cheaper phones and many other simple wireless devices currently only support 2.4GHz.
