Common Causes of the Issue

 

Before we dive into the solutions, let’s explore some common causes of this perplexing problem:

By addressing the IP address conflict, you can restore your computer’s internet connectivity and resume your work without further interruption.

 

  1. DNS Issues

 

Domain Name System (DNS) translates domain names into IP addresses. If your computer has trouble connecting to the DNS server, it may show a false “No Internet” message.

 

  1. Network Adapter Problems

 

Faulty network adapters or outdated drivers can also lead to connectivity issues.

 

  1. Firewall or Antivirus Settings

 

Sometimes, the computer says no internet but internet works due to overly strict firewall or antivirus settings. These security measures, while important for protecting your computer, can sometimes be too stringent and block your computer from accessing the internet. To resolve this issue, you can temporarily disable the firewall or antivirus software and check if the internet connection is restored. If so, you may need to adjust the settings of your firewall or antivirus software to allow internet access without compromising your computer’s security.

 

  1. Proxy Settings

 

Incorrect proxy settings can interfere with your computer’s ability to connect to the internet.

By keeping your network adapter drivers up to date, you can ensure smooth and reliable internet connectivity on your computer.
