Understanding the “DNS Server Not Responding” Error

If you’re experiencing the “DNS Server Not Responding” error on your WiFi connection, there are several ways you can fix it.

First, try flushing the DNS cache on your device. To do this, open the Command Prompt by pressing the Windows key and R, then type “cmd” and hit Enter. In the Command Prompt window, type “ipconfig /flushdns” and press Enter.

If that doesn’t work, you can try changing your DNS server address. Go to your network adapter settings, find the DNS section, and enter a different DNS server address such as Google’s DNS (8.8.8.8) or Cloudflare’s DNS (1.1.1.1).

Another solution is to update your network adapter driver. Go to the Device Manager, find your network adapter, right-click on it, and select “Update driver.”

If none of these methods work, you can try resetting your router or contacting your internet service provider for further assistance.

Using a Different Web Browser

If you’re experiencing DNS server not responding issues on your WiFi, you can try using a different web browser as a potential solution. Sometimes, the problem may be specific to the browser you’re currently using.

To do this, simply open a different web browser on your device and try accessing the websites that were causing the DNS server not responding error.

If the websites load successfully in the new browser, it indicates that the issue is related to your original browser. In this case, you can continue using the alternative browser or try troubleshooting the original browser to fix the problem.

python
import socket

def check_dns_server(host):
try:
# Create a socket object
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.settimeout(5) # Set a timeout for the DNS query

# Send a DNS query to the server
sock.sendto(b'', (host, 53))

# Receive the DNS response
data, _ = sock.recvfrom(1024)

# Check if the DNS response is valid
if data:
print(f"The DNS server at {host} is responding.")
else:
print(f"The DNS server at {host} is not responding.")

# Close the socket
sock.close()

except socket.timeout:
print(f"The DNS server at {host} is not responding.")
except socket.error as e:
print(f"An error occurred while checking the DNS server: {e}")

# Usage example: check DNS server response for Google's public DNS server
check_dns_server('8.8.8.8')

This code attempts to send an empty DNS query to the specified server (e.g., 8.8.8.8 represents Google’s public DNS server). It expects a response from the server within the specified timeout (5 seconds in this case). If a response is received, it indicates that the DNS server is responding. Otherwise, it reports that the DNS server is not responding.

Trying a Different Device to Access Websites

If you’re experiencing DNS server not responding issues on your WiFi, trying a different device to access websites can be a solution. Sometimes the problem might be specific to one device, so using another device can help determine if that’s the case.

To do this, follow these steps:

1. Press the Windows key and R together to open the Run dialog box.
2. Type “ncpa.cpl” and press Enter to open the Network Connections window.
3. Right-click on your active network connection and select “Disable.”
4. Connect your alternate device to the same network and try accessing websites.
5. If the alternate device can access websites without any issues, then the problem may be with the original device.

By trying a different device, you can narrow down the cause of the DNS server not responding error and focus on finding a solution that works for your specific device.

Restarting Your Router

Restarting your router can often resolve DNS server not responding issues. This simple method can help fix connectivity problems and get your WiFi back up and running. Here’s how to do it:
