Router not connecting to network

1. Was running the R7000 with DSL until last week.  Very easy set-up and worked like a champ.

2. Replaced DSL with uverse.

3. Connected the gateway to the router with an ethernet cable.  Disabled wireless on the gateway.

4. Lights on R7000 indicate there is internet access.

5. Netgear genie network map recognizes the gateway and router.

And this point I figure it is idiot proof to set the router to AP mode and off I go but . . .when I log into www.routerlogin.com or net I get the message "You are not connected to your Router’s WiFi network. To access routerlogin.net, your device must be connected to your Router’s WiFi network. Check your current connection and try again."

If the R7000 indicating light show there is internet access.  If the Netgear genie Network map identifies the router why can't I access it?   Should be a simple task to log on the router change the AP mode and, with the gateway wireless disabled, us the gateway as a simple modem supplying the router.  But the Netgear network map shows the gates way in the center with devices surrounding it.  I would think it would show the R7000 in the center with the gateway being between the router and internet.
