Unusual Link Problem
Unusual Link Problem
Set the main DNS address to 1.1.1.1 and the backup to another reliable provider like 9.9.9.9 or 8.8.8.8. Your router doesn't need to act as the primary DNS server since it can't resolve anything on its own—it will pass requests along based on its settings, making it ineffective in that role.
After updating the DNS on the gateway, every client linked to it needs to log off and back in or risk continuing to use the previous DNS settings.
It's often about DNS settings. Most routers can store and forward DNS queries, but this can lead to problems. Setting the primary DNS to 1.1.1.1 removes the router from the DNS resolution process. Give it a try and let us know if it works. To verify DNS issues, run the following steps during an outage: open command prompt and type ping 1.1.1.1. If you see the usual response, your internet should be functional. If you encounter a hostname error, DNS might not be working.
I managed to reach external sites (usually I ping Webex server at work, it's become a routine) but hadn't tested 1.1.1.1. It functions properly. The only change was disabling cyber security. Experimenting with it on and off shows it often blocks desired sites while allowing safe ones. Centurylink has added its own filters that don’t align with my needs. I remain cautious enough to avoid issues so far. This situation is now resolved and marked accordingly. Thanks to all who assisted. Eric the Grey
