A network proxy is a gateway that acts as an intermediary between a local network (such as all devices within the company or in a building) and the internet. It can provide an additional layer of security, privacy and improve performance when connected to Wi-Fi or Ethernet.
To configure a proxy in Windows 10 you can either use the settings app or manually edit your configuration. If you’re using the Settings app, choose Proxy under Network & Internet. You can skip this step in the event that the Use a Proxy Server switch is already disabled. If not, you can turn it on and then enter the proxy server’s address and port information.
If you’re using the proxy service in a business or school environment it is possible that you will be prompted by the IT administrator to make use of the Web Proxy Auto-Discovery Protocol (WPAD) script to configure the proxy automatically. This method is more reliable that manual configuration.
You should also consider disabling any third-party software that might be interfering with your connection to the internet or changing your settings. This includes antivirus, VPN, and firewall programs. This is especially helpful in the event that you encounter an error message that says “Windows could not detect this network’s Proxy settings original site automatically.”
If all else fails you can attempt a system reset. This will erase any programs and drivers that were installed prior to the restore point was created, allowing you reinstall your system’s default settings. This should solve the issue which will allow you to connect to the internet once more without encountering an error message.
