Feb 29, 2024 | Troubleshooting, Blog, How to | 0 comments

Have you ever tried to open a website or use an internet-connected app on your computer or phone, only to be met with the cryptic error message “DNS Probe Finished No Internet”? This confusing technical glitch can be frustrating and difficult to resolve.

The Domain Name System (DNS) acts like the phone book of the internet, translating domain names to IP addresses. When DNS fails, your device can’t locate resources online. Issues with your ISP’s DNS servers, network, or device settings are common culprits.

Fortunately, with the right troubleshooting steps, you can often fix the “DNS Probe Finished No Internet” error yourself without waiting for your ISP to solve it. This guide will walk you through how to diagnose the cause and resolve it on Mac, Windows, Android, and other devices.

What Does DNS Probe Finished No Internet Mean?

The error message “DNS probe finished no internet” means that your device is unable to reach the internet due to a problem with the Domain Name System (DNS).

DNS is like the phone book of the internet. It translates domain names that humans understand (like www.google.com) to IP addresses that computers use to locate resources on the network.

When you get the “DNS probe finished no internet” message, it means:

  • Your device was able to send out a DNS request to try to resolve a domain name to an IP address
  • The DNS request was completed, but the DNS server responded by saying it could not resolve the domain name
  • Without being able to resolve the domain name to an IP address, your device cannot reach the internet resource you were trying to access.

To fix it, you typically need to troubleshoot your network and DNS settings. Steps like flushing the DNS cache, resetting network settings to default, using public DNS servers, and checking for software conflicts can resolve the issue.

What Causes the DNS Probe Finished No Internet Error?

The “DNS Probe Finished No Internet” error message indicates that your device is unable to resolve domain names to IP addresses due to a problem with the Domain Name System (DNS). There are several potential causes for this:

1. DNS Server Issues

The most common cause is that your Internet Service Provider’s (ISP) DNS servers are malfunctioning or unreachable. DNS servers sometimes go down due to power outages, maintenance, or other issues. If your device’s DNS settings point to non-working DNS servers, you’ll get the “DNS probe finished no internet” error when trying to access websites or internet-connected apps.

2. Incorrect DNS Settings

Sometimes the DNS server addresses configured on your device may be invalid or point to non-working servers. For example, if you manually entered a custom DNS address that is incorrect, or the DHCP-assigned DNS servers from your router are not functional, this can cause the DNS probe error.

3. Network Connectivity Problems

Issues with your modem, router, or ISP connection can prevent your device from making DNS queries. For example, a loose network cable or wifi connectivity problems could cause the error. Check that you have strong signal strength and no packet loss. Restarting the modem/router may help.

4. Software Conflicts

Other programs like VPNs, antivirus software, ad-blockers, proxies, or browser extensions can sometimes disrupt DNS requests and cause the DNS probe error. Temporarily disabling these programs can determine if they are interfering with DNS.

Diagnosing the specific cause requires checking your network settings, DNS configuration, and connectivity. The troubleshooting steps in the next sections will help identify and fix the issue.
