Hi, you can enable either the 5GHz and/or the 2.4GHz on a per AP basis in the RF Profiles. See it in the documentation: https://documentation.meraki.com/MR/Radio_Settings/RF_Profiles I am not sure if this is also possible in the MX67W as I do not have such an MX. But i would expect it. So on a per AP basis you can do it. In your case you would need to go on a per SSID, where you can choose either dual band or 5GHZ only. So I would try to implement one SSID with only 5GHZ. The second I would try to configure dual band and just unassign all the channels of the 5GHz. I am not sure if this will work...but I would try to do it this way. hope it helps
