With the troubleshooting techniques listed below, you should be able to resolve the DNS Probe Completed No InternetError issue if it is preventing you from utilising the Internet on your computer.
DNS Probe Finished No Internet
Your computer depends on the DNS Server to match the requested Domain Name to the IP Address when you try to access any website by typing its Domain Name (for example, YouTube).
Your computer is essentially trying to tell you that it cannot execute your request because of connectivity issues at the DNS Level if it displays the message DNS Probe Completed No Internet Error.
Several factors, such as small software bugs, network connectivity problems, or overloaded or malfunctioning DNS servers operated by your internet service provider, can contribute to this difficulty.
1. Clear Browser Cache
Launch Chrome Browser, select the 3-dot menu icon, then select More Tools > Clear Browsing Data.
Choose “All Time” as the Time Range on the following screen, then click the “Clear Data” option.
2. Power Flush Modem/Router
It is advised that you power cycle the modem/router before moving on to additional troubleshooting techniques.
Wait 60 seconds before unplugging the modem or router from its power source. Reconnect the router or modem to its power source once 60 seconds have passed.
See if you can now connect to the internet without receiving any problem messages after waiting for the Router/Modem to fully restart (all lights turned ON).
3. Reset Network Adapter (Winsock Reset)
In the search bar, type Command Prompt. Next, right-click on Command Prompt and choose the Run as Administrator option.
Type the command “netsh winsock reset” in the Command Prompt window.
Close the Command Prompt window after the command has been run, then restart your computer.
Try to connect to the internet after the computer has restarted to determine whether the DNS Probe Completed No Internet problem is still present.
4. Update Network Adapter Driver
Choose Device Manager by performing a right-click on the Start button. Expand the Network Adapters entry on the Device Manager Panel, then choose the WiFi Adapter with the right click and the Update Driver Software option.
Observe anything that says Network, 802.11b, or has WiFi in it if you see multiple entries.
Choose the option to automatically search for updated driver software on the following screen, then follow the on-screen directions.
5. Flush DNS and Renew IP Address
Enter the command “ipconfig /flushdns” into the Command Prompt window after opening it as an administrator.
In a similar manner, write netsh int ip reset and press Enter, followed by ipconfig /release and Enter, and ipconfig /renew.
Restart the computer and close the Command Prompt window.
6. Disable Proxy Servers
Use of Proxy Server Configuration is a frequent cause of network connectivity problems.
Start by right-clicking and selecting Run. Enter inetcpl.cplan in the Run Command window and press OK.
Choose the Connections tab on the Internet Properties screen, then click the LAN Settings button.
Uncheck the Use a Proxy server for your LAN option in the Proxy Server section on the following screen.
Note: Ensure that the option for Automatically detect settings is chosen.
To save the changes to your computer, click OK.
7. Switch DNS Servers
Your Internet Service Provider’s DNS servers may be overloaded or experiencing issues if you frequently experience poor network connectivity on your computer.
By using Google’s Public DNS service or one of the other Free DNS Service Providers like OpenDNS or Cloudflare in these situations, the issue can be quickly resolved.
