I recently upgraded to windows 10 and starting watching YouTube videos on some of the features. I was watching a video about how to make my PC 100% faster with windows 10 and started following the steps. One of the steps was to change my preferred and alternate DNS server to 8.8.8.8 and 8.8.4.4. I did this and carried on with the rest of the video. Everything was good until I restarted my PC, I had no connection. The title of the thread is the error message I got when I tried troubleshooting my problem. So I backtracked and set the DNS server address back to automatic but that didn't help. What should I do?
