I guess this works, if inefficiently, in many cases. But it's a real problem now that Microsoft is adding DNS over HTTPS capabilities to Windows. (It's already in the Insider previews, they'll be rolling it out in release versions in an update.) It automatically detects whether DNS servers can do DNS over HTTPS, which of course the router does not.
Is there a way to make the Orbi tell DHCP devices to use the DNS servers specified in the configuration? If not, it will become a major hindrance to security as DoH gets widely rolled out.
The router's DNS server is an internal server. The Orbi uses the ISP or user provided 3rd party DNS servers, such as Google, Level 3, Open DNS, etc.. DNS over HTTPS server implementations are already available free of charge by some public DNS providers.

That wasn't my question.
A DHCP server gives DNS addresses to devices. Orbi's DHCP server is broken and always gives the router's address as the DNS address. So my Windows computer thinks that the DNS address is 192.168.1.1, rather than the address I configured.
I use a service that supports DoH. But Windows (again, for now I'm talking about the Insider versions, but this will soon be true for release versions as well) detects that by just trying to do a DoH request. And that will always fail, because the Orbi doesn't support DoH.
I'm not expecting the Orbi to support DoH. But its DHCP server should be able to correctly pass along the correct DNS servers rather than incorrectly giving its own address.
