Linksys EA9600 not getting ip on wireless

I am an openwrt newbie, and have only used Luci. I set up the three radios wit different IDs as access points. but cannot get ip addresses assigned. Connection and authentication work. I'm sure there must be something I'm missing in configuring through Luci, but I don't know what it is. Can someone help out a newbie and point me in the right direction?
