DNS server isn't responding

Hi i occasionally get this message when i run troubleshoot and i've read through the forums to change my dns server ip4 but that does not work (would changing my ip6 help?). I can connect to the router but cannot access the internet sometimes. The internet turns on and off and i would have to wait 5 minutes for it to work again. my ipconfig is below

EDIT: this also happens to another laptop
