Couldn't install 3 Cisco Business APs(cbw240ac) at the same time

[htetmyet]

I couldn't install 3 Cisco Business APs(cbw240ac) at the same time. Those Aps are in the same subnets of ISP Router's DHCP Scopes. Firstly, I configured First APs as SSID-AP1. Then it's working properly with its SSID-AP1. Then I configured 2nd APs as SSID-AP2 and then 3rd one. 

The problem is I just see only SSID-AP1 and AP2 and Ap3 are not working. When I turn off AP1 and AP3. Then I can see SSID AP2 and working. Similarly, AP3 is working with its SSID AP3 when I turn off AP1 and AP2. I know the root cause of this problem because I configured those 3 APs as Primary. That's why these 3 APs are not working together as those all are primary APs. 

1. What I want to achieve is I want to use those 3 Aps as a Standalone AP. Every Aps must function its own SSID and Password.

2.Let say's it cannot. Can I create 3 SSID in primary AP and then push to the rest two APs. If so, we can use 1 SSID for 1 AP although they are not standalone. 

Please kindly help me on this case! Professionals.

Let me know how to solve this issue.

Ensure that there is no Primary AP running in the network other than the CBW AP during setup or daily
operation of a CBW AP network. The Cisco Primary AP cannot inter-operate or co-exist with other Primary
APs in the same network.

Note : i would suggest to make one of the AP as primary and use all SSID and other as subordinary AP for the rest of the SSID.

1. Using multiple CBWs as standalone APs in the same network is not possible. When a CBW AP boots, it searches for a primary AP. If it finds one, it will try to join it as a subordinate AP and will not become a primary AP itself.

2. Yes, you can create three WLANs on the primary AP and then assign SSID-AP1 to AP1 only, SSID-AP2 to AP2 only and SSID-AP3 to AP3 only. You do that by creating three AP groups and assigning one WLAN and one AP to each group.
