So the new Omada Controller V4.1.5 is missing the option on 2.4GHz to select "802.11n Only" and on 5GHz select "802.11ac Only". IThe only option on 2.4GHz is "802.11b/g/n mixed" and on 5GHz "802.11a/n/ac mixed" These default mixed setting is extremly slow. On the previous Omada Controller software version 3.2.10, you were allowd the option. Am I missing something? Is there a way to change this via SSH? The 3.2.10 software allows for me to change this setting but show no client data, on the other hand version 4.1.5 gives me all the client data without the ability to change the Radio mode. Either way this software is usless to me. 

Thank you for any input.
