If you’re seeing the “Windows could not detect the proxy settings of this network” error The first step to take is restarting your router and computer. This will close any open applications and reset the proxy settings back to their default state that should fix the problem for most users.
If that doesn’t help, you can try disabling any firewalls, antivirus software or VPN software that may interfere with your Internet connection. You can do this by selecting the settings for each of these programs, and then removing them one at a. After you have disabled all of these apps Try reconnecting to your Internet and see if it still occurs.
If you are unable to solve the issue with any of these methods, you may want to think about a complete system restore in Windows. This will restore the default settings for your network, and also remove any changes that might have caused the problem. You can do this by navigating to the Control Panel and then clicking on “Internet Options.” Once you’re in this window, uncheck the boxes labeled Automatically detect settings and Use a proxy server for your LAN. Remember that this procedure will only affect your current user account therefore if you’re using the computer of a shared user, you’ll require repeating this process for any other users. You can also disable proxy settings using the Registry Editor, however this is a bit more complicated and could cause problems in the future.
