Using ATP100 as Wireless AP Controller

Hello All,

I purchased a NWA210AX AP because I'm less and less happy with Unifi products. I want to use my ATP100 as a Wireless AP Controller. I'm having trouble finding the setup instructions to do this. The AP is getting an IP through DHCP from the ATP100, but I'm not seeing it any of the AP lists.

I am not using Nebula currently. If I need to add the ATP100 to Nebula, I'm open to doing that.

Thanks,
-John
