Are you getting any error message on the deco app? What colors are your decos displaying? Also do you know the model number and the hardware version? Both can be found on the bottom of your decos

Regardless of mode (Router or AP), you have always had to have at least one Deco unit, designated as the main unit, connected to the source of the internet connection.  Whether that is through a router, gateway, or mode, the main Deco must be physically connected.
