Netgear C7800 Firmware V3.01.36 and Pihole not working properly

I can, and I fear you are not going to like this.

The expected outcome for this would have been a consistent 0.0.0.0
I am afraid that if your router does not expose any configuration option to change this, your WiFi devices will always be forced to use the DNS server your router is using, at least with its current firmware.

EDIT: You may want to reverify if you can revert your router to another firmware, as linked above (click on up arrow ‘ go to the quoted post ’ below):

@Bucking_Horn

Some users got lucky reverting to some older firmware, e.g. Setup on Netgear X4S Router (R7800)

Title updated. Thank you very much for your assistance throughout this. I will call my ISP when I have the chance and see if there is any way to downgrade the firmware and attempt again. If not, I will be leaving this thread as is.

While not the best news, 90 percent of my traffic is done through LAN, so I will accept the result as somewhat of a success. However, for others with the same router/modem I imagine this will be tragic news.

I have the same Netgear C7800 router and my firmware version is 3.01.38 so i guess a little newer than his .36 version. And i have the same issues. I read that post you linked about older version. But how do you even change the firmware? I don’t see anything related to it in settings for even updates. Doing a duck search says the ISP updates the firmware. So how would i know which to revert to and if i found one how would i do it if CoX is the one that controls it?

I have also read that the firmware is pushed out by the ISP for the combo. I am going to call my ISP to see if there is any way to upgrade/downgrade.

Personally, I will not be buying a combo in the future. I liked the idea, but I will be purchasing a modem on its own that is good for high speeds, and a separate router that works with high speeds and allows more customization on the firmware. To expand, there are open source firmwares like DD-WRT that work with specific routers. I will likely be looking at their list of compatible routers and choose one from there as I am a fan of FOSS.
