DNS Server Not Responding: Home Network Fixes

A DNS Server Not Responding error prevents your device from connecting to websites because it cannot communicate with the DNS server responsible for translating domain names into IP addresses. The issue is commonly caused by router problems, incorrect DNS settings, ISP outages, corrupted DNS cache files, or network adapter errors.

If you’re wondering How to Fix DNS Server Not Responding, the solutions below address the most common causes found on home networks.

Causes of DNS Server Not Responding

Several issues can trigger a DNS Server Not Responding, including:

• Router DNS configuration problems can also affect the router not connecting 
• ISP DNS outages
• Corrupted DNS cache
• Incorrect DNS settings
• Network adapter issues
• Firewall or antivirus interference
• VPN or proxy conflicts
• Outdated network drivers

Identifying the source of the problem makes troubleshooting faster and more effective.

Restart Your Router and Modem

Temporary network glitches are one of the most common causes of DNS Server Issues.

Steps

1. Turn off your modem and router.
2. Unplug both devices for 30 seconds.
3. Turn the modem back on.
4. Wait until the connection stabilizes.
5. Turn on the router.
6. Test your internet connection.

This simple restart refreshes DNS communications and often resolves the issue immediately.

Flush the DNS Cache

A corrupted DNS cache can result in a DNS Lookup Failed message.

Windows

Open Command Prompt as Administrator and run:

ipconfig /flushdns

Restart your browser and test the connection again.

Renew Your IP Address

Refreshing your IP configuration can resolve communication problems between your device and the network.

Run the following commands in Command Prompt:

ipconfig /release

ipconfig /renew

This forces your computer to obtain updated network information from the router.

Change DNS Servers

Switching to a reliable public DNS provider is one of the most effective ways to fix a DNS Server Not Responding problem.

Google DNS

• 8.8.8.8
• 8.8.4.4

Cloudflare DNS

• 1.1.1.1
• 1.0.0.1

Quad9 DNS

• 9.9.9.9
• 149.112.112.112

If your ISP’s DNS servers are unavailable, changing DNS providers can restore internet access immediately.

Check Router DNS Settings

Incorrect Router DNS Settings can affect your entire network and cause WiFi connection issues across devices. 

Log in to your router’s admin panel and verify:

• DNS addresses are correct
• Automatic DNS configuration is enabled if required
• No invalid custom DNS entries exist

Save changes and restart the router after updating settings.

Disable VPN or Proxy Connections

VPNs and proxy services can interfere with DNS requests.

Temporarily disable:

• VPN applications
• Browser proxy extensions
• System proxy settings

Then test whether websites load normally.

Restart the Network Adapter

Network adapter issues can prevent your device from reaching DNS servers.

Windows

1. Open Network Connections.
2. Disable the active adapter.
3. Wait a few seconds.
4. Enable it again.

This refreshes the network connection without requiring a full restart.

Update Network Drivers

Outdated drivers can contribute to recurring DNS Connection Problems.

Steps

1. Open Device Manager.
2. Expand Network Adapters.
3. Select your adapter.
4. Choose Update Driver.
5. Install available updates.
6. Restart your computer.

Updated drivers improve overall network stability and compatibility.

Check Firewall and Antivirus Software

Security software can occasionally block DNS traffic.

Temporarily disable your firewall or antivirus software and test the connection. If the error disappears, review the software’s network settings before re-enabling protection.

Reset Network Settings

If the problem continues, Resetting network settings can fix hidden WiFi connection issues and restore connectivity.

Windows

Go to:

Settings → Network & Internet → Advanced Network Settings → Network Reset

After the reset completes, reconnect to your network and test internet access.

Contact Internet Service Provider or WiFi Technician

If the issue continues even after trying all troubleshooting steps, the problem may be outside your home network. In some cases, service disruptions from your Internet Service Provider or regional network faults can prevent proper internet access. These situations usually cannot be resolved through device-level settings.

You should contact your ISP to check for outages, line issues, or configuration problems on their side. If the connection problem is caused by hardware faults or incorrect home network setup, a professional WiFi technician can inspect your router, fix configuration errors, and restore stable connectivity.
