This looks pretty simple and I have managed to accomplish this with other routers(Asus, Netgear) years ago, but this time I seem to have the strange problems.
1. If I disconnect the wired connection between the routers, I am able to access 192.168.1.1 admin.
2. If I connect the two routers, the Archer A7 disappears. All devices connected to Archer A7 get an IP address from 192.168.0.1/24 subnet. There is no way to connect to 192.168.1.1, even through a browser or SSH. Heck the Archer A7 does not even appear in any LAN-scan utilities and even the attached devices list for 192.168.0.1. But it's there, why? Because the devices are still connected to Archer's SSID, and are able to access the internet.
Assuming you are using a recent build you can do one of two things.
1. Hit the reset button and connect the WAN port of the Archer to the ISP router that should work right out of the box but the routers will be on different subnets
2. Hit the reset button and setup as a WAP: https://wiki.dd-wrt.com/wiki/index.php/Wireless_access_point

You need to describe in better detail what you want to accomplish because right now it sounds like the modem/router combo is doing all the heavy lifting and what you want to accomplish the way you've written it is not possible. The DNS from the A7 will be "overwritten" likely by the modem/router combo with your present setup.
Usually, you would put the modem/router combo from the ISP into bridge mode and let the A7 do all of the work for you; but, again, we don't know what you're really trying to accomplish so I would start with that full explanation first and then we can point you to the right guides to read.
P.S. I changed your subject to something more meaningful for people than what you originally posted. _________________ FORUM RULES
What you've described pretty much sums it up. Currently, I am wirelessly connected to the ISP router which acts as a DNS and DHCP server as well.
I wish to connect Archer A7 to ISP router with a wired link, turn off wireless on ISPR, and have Archer A7 be used as a wireless AP for all devices. The Archer-A7 also needs to handle DNS for the network.
Please do note that the sole purpose of placing an extra router is DNS. The ISP router does not have a DDNS option, and it resets to default ISP DNS every few hours. This makes it near impossible for me to use NextDNS.
The big problem I keep running into repeatedly is the Router admin interface does not proceed ahead from the Status page, no matter what link I click on. I have tried resetting the router(I know it got reset because it asked to set a new admin/password); I've left it without power supply for almost 2 hours; and numerous reboots.
Sometimes it works for a couple of pages, then goes back to loading perpetually. What is even more strange that "a few times" it works fine on the mobile browser, while at the same time on the desktop browsers(Firefox/Safari/Edge) it refuses to proceed ahead from the status page. It is utterly baffling.
This is the problem that needs to be addressed first, before I even go about setting things.
So yes, Private Browsing fixes i To the extent that I've been able to complete the entire setup by private browsing.
Everything is up and running perfectly.
I've tried enabling DNSmasq and NextDNS through it, however it hasn't really worked. A note here that my WAN Connection type is Disabled in DD-WRT. Is it supposed to work with WAN disabled in the router?
