  4. Check the Security Application

    There are some security features in your antivirus software that might lead to Windows could not automatically detect this network’s proxy settings. The application actually blocks the proxy addresses so that no unauthorized intruders can gain access to your network. When you are confident about the proxy address that it cannot be breached, it’s better to uninstall the security software for some time. 

    From the list of installed applications, search and find out the security software. When the removal process is done, reboot your system and check the proxy settings. 

  5. The SFC Scan

    Perform the SFC scan for the entire system with the help of the “sfc/scannow” in the Command Prompt. The operation might take 8 to 15 minutes. The elapsed time duration basically depends on the system configuration. After the successful scan, your computer will definitely be able to detect the proxy settings correctly. 

  6. Switch to Default Internet Settings

    Switching on to the default internet settings will require the formatting process. Type Internet Options in the Cortana bar. Navigating through the Advanced tab in the Internet Properties, you will easily locate the Reset button at the end. 

    Click on it to get the confirmation window. Once again, click on Reset. Now, finish the process with the help of the OK button. Your system will be free from getting the Windows could not automatically detect this network’s proxy settings error.

  8. Let the System detect IP Address Automatically

    There are two main ways to configure the internet — The first one is putting all the correct internet credentials and the other is letting the system do it automatically. Performing these two procedures will solely depend on the type of network connection you use. Your computer will only detect the network connection automatically if and only if you are using a static IP.

Sometimes when your broadband connection doesn’t work, you take the help of the mobile internet service. This service does not need any type of proxy address or settings. If needed, contact your mobile operator helpline to get more valuable information. As the involvement of the security application is already there, look for your desired choices. 

Make sure you choose such a security application that will not interfere with the network configuration or settings. On the other hand, this will also help to eliminate many technical glitches. Further, before connecting to the internet, make sure you delete all the cache files from your system. These files can create a barrier in the network settings.
