Restart your modem and router 

Sometimes, the issue can be due to a temporary glitch in your network hardware. So, try unplugging your modem and router from the power source for about 30 seconds, then plug them back in and wait for them to fully reboot.

Flush the DNS cache

Your computer stores the IP addresses of websites you've recently visited in its DNS cache. Sometimes, this cache can become corrupted, leading to the "DNS server isn't responding" error. You can flush the DNS cache by opening the Command Prompt (search for "cmd" in the Start menu), then typing the following command and pressing Enter: "ipconfig /flushdns".

Change your DNS server

Your ISP's DNS server may be down or experiencing issues, causing the error. You can try changing your DNS server to a different one, such as Google DNS or OpenDNS. To do this, go to your Network and Sharing Center, click on "Change adapter settings," right-click on your network connection, select "Properties," click on "Internet Protocol Version 4 (TCP/IPv4)," and then click "Properties" again. From there, select "Use the following DNS server addresses" and enter the DNS server addresses you want to use.

Disable your firewall or antivirus software

In some cases, your firewall or antivirus software can interfere with your network connection and cause the "DNS server isn't responding" error. Try disabling them temporarily to see if it resolves the issue.

Update your network adapter driver

If your network adapter driver is outdated or corrupted, it can cause issues with your network connection. You can try updating your driver by going to your Device Manager, finding your network adapter, right-clicking on it, selecting "Update driver," and then following the on-screen instructions.

By following these steps, you should be able to fix the "DNS server isn't responding" error and regain access to the internet on your computer.
