Need help adding a 3rd AP R320 to my existing Lennar built network to extend wifi

[horica_bau]

Hi

I have a Lennar built home with Ruckus Wi-Fi system. I have two R320 on on each level of the house. I have purchased a 3rd AP identical with existing ones R320 and installed it in the back bedroom to offer coverage to the backyard. i have connected it in the ruckus switch. I saw the configure.me.xxxx network on my Wi-Fi and tried to add it to the network. It gives me the error "unable to fetch default configuration from AP" then the Wi-Fi "configure.me" network disappears. 

the ne AP it shows in the unleashed app but it shows offline. 

the PWR led is steady green and CTRL led is pulsating green.

How can i make the AP online and have my network extended. 

Thank you
