Network issues are common with Windows systems but are mostly resolvable once you understand the cause. Imagine a situation when your system is connected to the internet and the Wireless icon shows connected but websites aren’t opening. Changing the browsers do not help. There is a possibility that the issue is with the DNS server. If yes, please read this article for the resolution.
What is DNS?
The Internet doesn’t understand our language. So, if we enter the URL of a webpage on the address bar of a browser, the DNS server converts it into a numerical value (IP address of the website) which can be read by the internet. If the DNS (Domain Name System) stops converting the URL to the numerical value, you will encounter the error DNS Server not responding. In general, for any issue related to the DNS, you will not be able to access websites.
How to tell if the issue is with the DNS server?
If the DNS server is problematic, you might not be able to open the website by entering its URL but would still be able to open it by entering the IP address of the website. Eg. Enter Google’s IP address 172.217.4.46 in your browser’s address bar and hit Enter. If it opens Google.com, then you have isolated the cause.
Further, you can try the Ping test.
- Press Win+R to open the Run window and type the command cmd.
- Hit Enter to open the Command Prompt window.
- In the Command Prompt window, type the command ping google.com and hit Enter.
- If it doesn’t return all 4 packets, type ping 172.217.4.46 and hit Enter.
- Should you receive all 4 packets with the second command, the issue is definitely with the DNS server.
How to resolve DNS issue on Windows 11/10
To resolve DNS related issues on your Windows computer, try the following solutions sequentially:
- Check for issues with the ISP
- Power-cycle modem, router, and computer
- Renew IP, Flush DNS, Reset Winsock
- Perform a Clean Boot on the system
- Activate the Microsoft LLDP Protocol Driver
- Install latest Network Drivers
- Change Power Plan
1] Check for issues with the ISP
If the issue is with the ISP, any level of local troubleshooting would be useless. So, before anything else, please check other devices connected to the router for the internet connection. If other devices work fine, then the ISP is doing its job right. If you have no other device, then try connecting the computer directly to the modem.

2] Power-cycle modem, router, and computer
In case the system isn’t picking up the IP address properly, try the following solution:
- Switch OFF the modem, router, and computer.
- First start the modem only and wait for 2-3 minutes till all the lights are stable.
- Next, start the router and wait for 2-3 minutes till the light on the router are stable.
- Finally, start the computer.
This should solve the problem for many users, but if not, please proceed to the next solution.

In the elevated Command Prompt window, type the following commands sequentially. Hit Enter after each command to execute it.
ipconfig /flushdns ipconfig /registerdns ipconfig /release ipconfig /renew NETSH winsock reset catalog NETSH int ipv4 reset reset.log NETSH int ipv6 reset reset.log Exit
This will Renew IP, Flush the DNS cache and Reset Winsock.
