A network proxy is a gateway that acts as an intermediary between the local network (such as all devices within the company or in a building) and the internet. It can provide an extra layer of security, privacy and speed when connected to Wi-Fi or Ethernet.
You can configure a proxy on Windows 10 either manually or using the Settings app. If you’re using the settings app, select Network & Internet and select Proxy. You can skip this step if the Use a Proxy Server option is already disabled. If not, turn it on and fill in your proxy server’s address and port details.
You may be requested by an IT administrator to use the Web Proxy Auto-Discovery Protocol script (WPAD) when you use a Proxy in a workplace or school environment. This method is more reliable that manual configuration.
It is also recommended to disable any third-party applications that could interfere with or alter your network settings. This includes firewalls, antivirus and VPN applications. This is especially useful when the error message that you receive states that “Windows did not detect automatically the proxy settings of this network.”
If all else fails you can try a reset of the system. This will remove all drivers and programs that have been installed since the restore point has been created, allowing you to restore the default settings of your system. This should solve the issue that prevented you from connecting to the internet without encountering the error message.
