What happens if you set the ISP modem for router mode then try option #2 with the R7800.

Does your ISP require any kind of WAN configuration with a user name and PW on the WAN account side by chance? 

 

Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.

 

DMZ or IP Pass thru is only seen on modems while there in Router mode. 

 

You can definitely put 3rd party FW on the R7800. I like Voxels.

For reference...

 

I can recommend the Voxel firmware for the R7800.  Have been using it for years.  Most users that install it, never look back.  It is essentially a polished version of the stock firmware.  It is very easy to give it a try and very easy to go back to stock if you do not like it.  Be sure and review the Readme file at the top of the Voxel site for background.  There is an active Voxel area over on Small Net Builders forums.  See attached screen snip.  Links below.

As a comment on your issue, there is a significant technology gap between your WNDR router and the R7800.  The cold startup sequence between the devices is important and not the same for all configurations.  For my setup to connect to the internet, I have to have the modem powered off and the router booted up with the internet connection led dark before I boot the modem.
