If the first DAP is connected to the router by wire, you can run it as access point and connect a second DAP in client (bridge) mode to the first.
But read the first post. The first DAP is connected wirelessly to the router, so it is cannected as client bridge. In this setup you can't connect another client bridge to it.
But it should be possible to connect the second DAP also to the router if it is in range.
