My Lennar home came with a ruckus. This week it is not connecting with my iphone. The light in the middle (Air) is not lit, but the other four are lit. Should the "Air" light be on to get internet connection on iphone?
No, if the access point is not part of a wireless mesh network then it should not be lit.
