I want to undo some of my setup on my network so I can redo it in a different configuration on the same machine. The first thing I wanted to do was disable my Adguard server, making sure I could still use the internet after.

I thought I had cleared out all of the settings in my router that made it use Adguard for DNS, but when I shut down Adguard afterward, all outside connectivity fell apart. I could still get to websites if I knew their specific IP address, but nothing that needed DNS worked. When I booted Adguard back up, everything started working again.

I have tried several options in the DNS server settings in my Asus router (TUF-AX5400). Is there something I need to do in Adguard first to make this work? Or is this maybe something I need to reset in my Asus router and then give it time and a few reboots to work?
