Looks like there's no internet connectivity

Hello.

I am aware that there are a lot of posts with this same title, and I have read a good part of them, but none of the solutions that are covered in them have helped me. I had that problem months ago, and yesterday I changed the computer. It was a big surprise that the updater worked on the first day, but today, second day, it is not working again. Not having the updater running is the same as not using OpenDNS, please need help.

Thanks.
