I keep getting an issue where my internet disconnects. I get the error message "The DNS server isn't responding." when I troubleshoot with windows. After restarting my router the connection comes back. I have been using 22.214.171.124 as my primary DNS server and google's DNS server as my backup. I have also reset it to default and am still getting the issue. I have previously had the same issue, but after a lengthy phone call with a technician and going through my router settings it was fixed. This was about a year ago. I have changed nothing since then (including the DNS server, those are the ones he told me to use) and the problem has returned. Here are two images of ping plotter tests I did. The first image is from right after it happened and the second is after restarting my router with the test still running.
Some more information:
I live in Cape Town and my fiber provider is Octotel.
I feel like I'm getting the same issue. Connection just dies randomly and you are forced to power off/on router to get the connection live again. Also in CT and on Octotel. It was happening before I went away overseas for 3 weeks and now I'm back it's still an issue.
