Topic: Wired network issue

I have had an issue with the wired connection via ethernet to my xbox one. Before it was working fine, but now it only works wireless. I have tried unplugging and the router and using different ethernet cable etc but the cable works for a pc so nothing is wrong there. I test the network connection in settings and it says DNS is not resolving Xbox server names. Is there any more things I can try to make this work?

I have tried to use wired connection for my xbox few times, but it never worked. Mine xbox one s is fairly New, bought it in March
