If you set the dns address manually for a device instead of relying on DHCP does dns work then? That should work fine no matter what your router is giving out.
So to clarify, what are you wanting to happen and what is happening instead?
This was my recommendation too. Simplest setup you could ask for to create a VPN connection between devices with wireguard as the base.
