Lennar Connected Home ICX 7150-c12p R510 AP Setup

I purchased a Lennar home with a ICX 7150 and R510 AP.  The wifi signal was broadcasting the Lennar assigned SSID and the ConfigureME-XXXX.  I downloaded the android app and connected to the ConfigureME net and followed the steps.  That’s where I’m stuck.  I don’t see the SSID I assigned during setup.  I can connect to the AP with Lennar provided password, but I don’t get an external IP.  I had an old wireless router and it works, so I know the connection is good thru the modem.  When I go back to the mobile app and try to access the app it says I’m not connected to the network and then takes me to the network settings.  When I did the initial setup with the Unleashed APP, I picked the typical install.I’ve done router setup for other manufactures, but this has me stumped.  Can someone point me to the documentation or explain how I can get this configured and maybe explain what I did in the setup with the mobile app?
