I've been running into this issue with my pc for the past couple days. I have had no internet due to a DNS issue. It was defaulted to automatic so I tried the Google DNS as well as the opendns addresses, nothing. I was, and currently am, hard wired but I also tried using WiFi. I have restarted, ipconfig -release and -renew, nothing. My pc is the only device running W10 in the house and it is the only device with this issue. Running the trouble shooter I get "the DNS server is not responding" when on automatic and "windowsbcant communicate with the device or resource (primary DNS server)" with any DNS I put in. Any help into resolving this is greatly appreciated.
