How Do I Fix a DNS Problem on My Router with Easy Troubleshooting Methods

DNS Problem on My Router

DNS converts the domain names into IP addresses of the wireless routers, and it improves the networking equipment’s speed and performance. Router manufacturers, like Asus or D-Link, let you change the DNS server from the web interface. Switching to a new DNS server enhances the home network security. But, if you fail to configure the DNS settings, it could result in internet dropping issues.

Additionally, outdated router firmware could lead to DNS problems. A faulty ethernet cable can generate issues while connecting to DNS servers. Sometimes, you can get a DNS error for using an outdated web browser. Try accessing the router’s configuration page from a different web browser. It might resolve this connection error from the latest wireless routers.

Do you think about how do I fix a DNS problem on my router? Then, disconnect the power cables and reconnect them after 2-3 minutes. If that doesn’t work, then something might be wrong with these router units. Check if there is any wear and tear on the power resources. Replace the existing cables with new ones to fix the DNS issues.

Change the DNS Server

Wireless routers have primary and secondary DNS servers. Entering incorrect server values on the setup page could cause DNS problems. Thus, the router users should change this information to resolve the issue.

Many take an expert’s help to reconfigure the router’s DNS settings. But, you can do that without any technical knowledge. Here are the steps to change the DNS servers of the popular router brands:


First, open a web browser, write the internal gateway IP and press the “Enter” button. Enter the default username and password when prompted. Click “Sign In” to access the Asus router’s admin panel. Then, head towards the “WAN” section, click “DNS Server Automatically” and select “NO”.

Enter “” in the primary DNS server field. And, consider writing “” in the secondary DNS server box. Choose “Apply”, restart the wireless router, and operate without causing any DNS problems.


Do you use Linksys’s smart Wi-Fi router? Then, log in to the cloud account after entering the default password and email address. And, navigate to “Router Settings” when the new web page opens.

Choose “Connectivity” from the menu and select “Local Network” afterward. Go to the “DHCP Server” section and enable the DHCP server first. Additionally, you need to enter the default IP address of the router.

Choose the number of user who can use the Linksys router. Go to the “Static DNS 1” box and write “10:253:251:232”. Don’t write any DNS server value in the DNS 2 and DNS 3 field. Otherwise, it might prevent you from connecting the router to the PC. Choose “Apply” once you reset the DNS server settings of the Linksys router. Reboot the router, and connect it to the computer without any DNS issues.


It is important to acknowledge the DNS server value in the first place. TP-link router users might not overcome this critical error without that. Not aware of the primary or secondary DNS server address? Go to the “Network Map” tab after opening the admin interface. Select “Advanced”, tap on “Network” and choose “Internet” to find these details.

Click the “Advanced Settings” option to remove the DNS server address. First, opt for writing “8:8:8:8” in primary and “1:1:1:1” in the secondary DNS boxes. And, then select “Connect’, reboot the advanced router, and it won’t further display DNS error messages. But, this address is valid only for the Linksys router with Google DNS. Check the DNS address before you configure its settings.

Clear the DNS Cache

Sometimes, the DNS cache can restrict the router from connecting to the internet. Clear the router data to fix this error immediately. Did you connect a Windows PC with the router? Hold the Windows and R keys together to open the Run box and write “ipconfig /flushdns”.

Press the Enter button to remove the existing DNS addresses. Open a reliable web browser to recreate the DNS address of the router. Connect the wireless router with the Wi-Fi enabled devices without any further interference.

Moreover, the Mac device users need to hold the command and Space keys together. Wait until the Spotlight app opens, and then write “Terminal”. Choose it from the searched results immediately. Write “sudo killall -HUP mDNSResponder” and tap the “Return” key. It will clear the router’s DNS cache and restart the DNS process. Restart the dual-band router, and the DNS error message won’t pop up again. But, if the error persists, restart the device in the Safe Mode.

Alternative Troubleshooting Methods on How Do I Fix a DNS Problem on My Router

An antivirus program can sometimes conflict with the router’s DNS servers. Uninstall this program to fix the DNS error from the router. Furthermore, you should also disable the Windows Defender Firewall. Update the wireless card drivers from the Windows and Mac devices. And, reset the router if these solutions didn’t work.
