R6700V3 Wireless AP Issues

Okay, I'm at a loss.  I have a Netgear R7800 with firmware 1.0.2.92 as a main router.  I have this router connected through ethernet cable to the WAN port of a Netgear R6700V3 with firmware 1.0.4.128.  I set the R6700V3 into Wireless AP mode and it won't recognize an internet connection.  The port on the main R7800 is not lit up at all while the other ports that are in use blink white.  The WAN port light on the R6700 is blinking orange.  When I relocate the ethernet cable to a different port on the R6700 the associate port lights up white, but still no WIFI internet connection is available when connected wirelessly to the R6700. I have the R6700 set to auto assign IP in the WAP setting menu.  I can't see the R6700 as a connected device in the R7800 menus either. Prior to configuring the 6700 as a WAP, I changed the wireless channels between the two devices so they are not the same.  The SSID's are different names also.  Is there a way to configure the R6700 to extend my WIFI connection/use it as a wireless AP or a wireless bridge?  I'm begging to think this isn't possible.
