Are you getting DNS errors when surfing the web or connecting to the network? The Domain Name Resolution System (DNS) is a server that encrypts web page addresses so that browsers can connect. Sometimes, you lose connection to the server due to an installation error or a problem with the server. If you are having trouble connecting, read the First Step of the article to know how to fix this problem.
Steps
Confirm Connection

Connect to the network for another device. Before trying to solve this problem, use this approach to determine the cause of the problem. You can narrow the problem down to just a few quick checks. Connect another device to the router, wired or wireless.
- You can use another computer, phone or tablet. Anything that can access the internet to test the network.

Try accessing a website on a second device. If the DNS error still occurs, the problem lies with the router or network provider. If the device can connect to the website, the problem is with your device.
Restart the modem and router regularly. Unplug the modem and router. Let the device rest for about 30 seconds to release the electrical pulse and clear the memory. Plug the modem back in and wait for the connection to complete. After powering on the modem, connect the power cable to the router and start the device. This process may take several minutes.
- After restarting both devices, try connecting to a website. If the problem is still not resolved, read the next part of the article.

If using a mobile device, you can go to > settings > mobile data and reset the configuration.
Computer Troubleshooting

Try using another browser. This is the fastest way to test DNS connection. Get another free browser like Firefox or Chrome and try connecting to the internet. If the problem persists, it means that the error is not in the browser but in some settings on the computer.
- If the problem is resolved, you can try to fix the problem for the old browser. Usually the error comes from proxy settings. You need to go to the proxy settings in your browser and set it to Automatic.

Disable secondary connections. Sometimes Windows automatically installs the secondary connection. For the most efficient connection, you should only activate the frequently used connection. Open the Network Connections window by going to the Start menu or pressing the ⊞ Win key and searching for “ncpa.cpl”.
- Find secondary connections. You can see a list of connections. The main cause of DNS errors is the existence of “Microsoft Virtual WiFi Miniport Adapter” (Microsoft Virtual WiFi Adapter). IF you see it, right click and select “Disable”. [1] X Research Source
- Check the connection again. Wait a while and then open the browser. Try accessing a website. It takes a few minutes to load DNS, if the web is accessible, the problem is solved. If not, move on to the next step.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f0/Fix-DNS-Server-Not-Responding-Problem-Step-7.jpg/v4-728px-Fix-DNS- Server-Not-Responding-Problem-Step-7.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f0/Fix-DNS-Server-Not-Responding-Problem- Step-7.jpg/v4-728px-Fix-DNS-Server-Not-Responding-Problem-Step-7.jpg”,”smallWidth”:460,”smallHeight”:347,”bigWidth”:728,”bigHeight” :549,”licensing”:”<div class=”mw-parser-output”></div>”}
Delete DNS hosting. Many times the DNS archive is out of date and needs to be manually deleted. You can do this from the Command Prompt (Command Interpreter).
- To open Command Prompt, press ⊞ Win + R key and type cmd .
- Type ipconfig /flushdns . Wait for the command to be processed, then restart the computer.
- Check the connection again. If the problem persists, move on to the next step.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/38/Fix-DNS-Server-Not-Responding-Problem-Step-8.jpg/v4-728px-Fix-DNS- Server-Not-Responding-Problem-Step-8.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/38/Fix-DNS-Server-Not-Responding-Problem- Step-8.jpg/v4-728px-Fix-DNS-Server-Not-Responding-Problem-Step-8.jpg”,”smallWidth”:460,”smallHeight”:347,”bigWidth”:728,”bigHeight” :549,”licensing”:”<div class=”mw-parser-output”></div>”}
Change DNS server. You can manually enter an alternate DNS server to test connection. Do this by opening the “ncpa.cpl” window and then right-clicking and selecting enable connections. Select “Properties”. [2] X Research Source
- In the Networking tab, scroll down to find “Internet Protocp Version 4 (TCP/IPv4)”. Click on the item and then select the Properties button.
- Click on “Use the fplowing DNS server addresses”.
- Enter the number 208.67.222.222 in the “Preferred DNS server” field (primary DNS server)
- Enter the number 208.67.220.220 in the “Alternate DNS server” field (alternative DNS server)
- This DNS server is maintained by Open DNS, an open source DNS service.

Try connecting in Safe Mode. Restart your computer and enter Safe Mode, which downloads only necessary files for Windows, allowing you to determine if an anti-virus program or service is causing the connection failure. [3] X Research Sources
- You can disable the anti-virus program and see if the problem is fixed. If it is, you should remove the program and replace it with a new one.
- Restart the computer and hold down the F8 key.
- Select Safe Mode with Networking in the list of options.
- Checking connection. If you can access the internet successfully, the problem is with the software on the computer. Check the startup file and disable the program until the cause is found.
Troubleshooting for Routers
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b6/Connect-a-Cable-Modem-to-Your-Computer-Step-5.jpg/v4-728px-Connect- a-Cable-Modem-to-Your-Computer-Step-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b6/Connect-a-Cable-Modem- to-Your-Computer-Step-5.jpg/v4-728px-Connect-a-Cable-Modem-to-Your-Computer-Step-5.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Plug the computer directly into the modem. If you’re using a router to create an internal network, disconnect your computer from the router and plug an ethernet cable directly into the modem’s Ethernet port.
- Try loading the web page. If there are still DNS errors, the problem lies with the network provider. Contact them and report the DNS server problem.
- If the web is accessible, the problem is with the router. Connect the router to the modem, then connect the computer to the network to continue troubleshooting.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/69/Fix-DNS-Server-Not-Responding-Problem-Step-11.jpg/v4-728px-Fix-DNS- Server-Not-Responding-Problem-Step-11.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/69/Fix-DNS-Server-Not-Responding-Problem- Step-11.jpg/v4-728px-Fix-DNS-Server-Not-Responding-Problem-Step-11.jpg”,”smallWidth”:460,”smallHeight”:346,”bigWidth”:728,”bigHeight” :548,”licensing”:”<div class=”mw-parser-output”></div>”}
Enter an alternate DNS server. You can change your router settings to manually connect to an alternate DNS server. This helps confirm if the network provider’s DNS server is down.
- Open the router configuration page. Each router has a different way of opening, but you still need to enter the IP address in the address bar of your web browser. Refer to the online tutorial for more details.
- Open Internet preferences. Find the addendum called “Domain Name System (DNS) Address”.
- Set it to manual mode to use the DNS server you just entered.
- Enter the Open DNS server information (Primary – 208.67.222.222, Secondary – 208.67.220.220) or Google DNS (Primary – 8.8.8.8, Secondary – 8.8.4.4).
- Click Apply or Save Changes. Wait a while for the router to apply the change.
- Review. Open a web browser on your computer to access the web. If you can connect to the network as usual, the problem is in the DNS.

Reset the router. Sometimes the setup on the router fails, the fastest way to fix the problem is to reset the router to its default settings. Also reset wireless network settings and previous information.
- To reset the router, use a paperclip or sharp object such as a toothpick to hold down the Reset button on the back of the device.
- Reconfigure the router. After the reset, you need to reconfigure the wireless network (if you used one). The administrator account and password also need to be reset.
