Troubleshooting Sites Like Google, YouTube, and Facebook Not Working on Routers (Airtel Xtreme Fiber, TP-Link TL-WA850RE)

If you're experiencing issues with popular websites like Google, YouTube, and Facebook not loading on your Airtel Xtreme Fiber or TP-Link TL-WA850RE routers, it's possible that the DNS server is causing the problem. This article will guide you through the process of troubleshooting and resolving the issue.

Understanding DNS Servers

A DNS (Domain Name System) server is responsible for translating domain names (e.g., ) into IP addresses (e.g., 142.250.74.46) that computers can understand. When a website is not loading, it could be due to a problem with the DNS server. In this case, you can try changing the DNS server to a public one, such as Google's DNS servers (8.8.8.8 and 8.8.4.4).

Checking the Connection

Before troubleshooting the DNS server, it's important to check the physical connections. Make sure the Airtel Xtreme Fiber ONT (Optical Network Terminal) is properly connected to the router, and the TP-Link TL-WA850RE range extender is connected to the router as well.

Changing the DNS Server

To change the DNS server on the Airtel Xtreme Fiber router, follow these steps:

1. Connect to the router's web interface by typing its IP address into a web browser (usually <192.168.1.1> or <192.168.0.1>).
2. Log in using the router's administrator credentials.
3. Navigate to the DNS settings page and change the DNS server to a public one, such as Google's DNS servers (8.8.8.8 and 8.8.4.4).
4. Save the changes and restart the router.

To change the DNS server on the TP-Link TL-WA850RE range extender, follow these steps:

1. Connect to the range extender's web interface by typing its IP address into a web browser (usually <192.168.0.254>).
2. Log in using the range extender's administrator credentials.
3. Navigate to the DNS settings page and change the DNS server to a public one, such as Google's DNS servers (8.8.8.8 and 8.8.4.4).
4. Save the changes and restart the range extender.

Flushing DNS Cache

If changing the DNS server doesn't resolve the issue, you can try flushing the DNS cache. This process varies depending on the operating system, but it usually involves opening a command prompt and typing "ipconfig /flushdns" (Windows) or "sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder" (Mac).

• Check the physical connections between the Airtel Xtreme Fiber ONT, router, and TP-Link TL-WA850RE range extender.
• Change the DNS server on the Airtel Xtreme Fiber router and TP-Link TL-WA850RE range extender to a public one, such as Google's DNS servers (8.8.8.8 and 8.8.4.4).
• Flush the DNS cache on your device.
