How do I resolve a DNS problem?

Answered by Jeremy Urbaniak

When it comes to troubleshooting a DNS failure, there are several strategies that you can try. These strategies are aimed at resolving the issue and getting your DNS working properly again. Let’s dive into these strategies in detail:

1. Restart Your Software or Device: Sometimes, simply restarting the software or device that you are using can fix the DNS problem. This is because restarting can clear any temporary glitches or issues that may be causing the problem.

2. Restart the Modem or Router: If restarting your device doesn’t work, the next step is to restart your modem or router. Unplug the power source, wait for a few minutes, and then plug it back in. This can help refresh the connection and potentially resolve any DNS issues.

3. Switch Browsers: If you are experiencing DNS problems with a specific browser, try switching to a different one. This can help determine if the issue is browser-specific or related to your DNS settings.

4. Pause Your Firewall: Sometimes, your firewall settings can interfere with DNS resolution. Temporarily disable your firewall and check if the DNS problem persists. If the issue is resolved, you can adjust your firewall settings to allow DNS traffic.

5. Clear Your Cache: Clearing your browser’s cache can help resolve DNS issues. Cached data can sometimes interfere with DNS resolution, so clearing it can give you a fresh start. You can usually find the option to clear your cache in your browser’s settings or preferences.

6. Disable Extra Connections: If you have multiple network connections enabled, such as Ethernet and Wi-Fi, try disabling the ones you are not using. Having multiple active connections can sometimes cause DNS conflicts and result in failure. Disable the extra connections and check if the DNS problem is resolved.

7. Keep Everything Updated: Ensure that your software, device firmware, and router firmware are all up to date. Outdated software or firmware can sometimes cause DNS issues. Regularly check for updates and install them to ensure optimal performance.

8. Check DNS Settings: Double-check your DNS settings to ensure they are configured correctly. You can do this by accessing your network settings and checking the DNS server addresses. If you are unsure of the correct DNS server addresses, you can try using public DNS servers like Google DNS ( and or Cloudflare DNS ( and

Troubleshooting a DNS failure involves restarting your software or device, restarting your modem or router, switching browsers, pausing your firewall, clearing your cache, disabling extra connections, keeping everything updated, and checking DNS settings. By following these strategies, you can increase the chances of resolving your DNS problem and getting your internet connection back up and running smoothly.
