Your DNS (Domain Name System) settings might be causing connectivity issues. Here’s how to check and update them:
Check your DNS server addresses to ensure they’re correct and not blocked.
Try using public DNS services like Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1).
Flush your DNS cache to remove any corrupted data.
Use the Command Prompt or Terminal
Utilize the Command Prompt (Windows) or Terminal (Mac) to run diagnostic commands:
Use the `ipconfig` command to release and renew your IP address.
Run the `ping` command to test connectivity to a specific website or server.
Use the `tracert` command to trace the path of your internet connection.
Check for ISP Throttling
If you suspect ISP throttling, try the following:
Contact your ISP to ask about any throttling or bandwidth limitations.
Use online tools, such as Speedtest.net, to test your internet speed.
Consider switching to a different ISP or plan that offers faster speeds.
Conclusion
A blocked internet connection can be frustrating, but by following these steps, you should be able to identify and resolve the issue. Remember to stay patient and methodical in your troubleshooting approach. If you’re still experiencing problems, consider seeking help from your ISP or a professional IT consultant.
Remember, a fast and reliable internet connection is just a few steps away!

What is the difference between a modem and a router?
A modem is a device that connects to the internet via a broadband connection, such as a cable or fiber optic connection, and converts the signal into a format that can be used by your devices. A router, on the other hand, is a device that connects to the modem and directs the internet signal to your devices, allowing them to connect to the internet.
In simple terms, the modem brings the internet into your home, and the router distributes it to your devices. While some devices combine the functions of a modem and router into one unit, they are typically separate devices that work together to provide you with internet access.
How do I reset my router and modem?
Resetting your router and modem can be an effective way to resolve connectivity issues, but it’s essential to do so correctly to avoid losing your customized settings. To reset your router, press and hold the small button on the back or bottom of the device for 10-15 seconds, then release it. This will restore the router to its factory settings.
