Restarting your router and computer is the first step to do if you are receiving the error message «Windows could not determine the proxy settings for this network». This will shut down all open applications and reset proxy settings to default settings. For the majority of users, this will fix the problem.
If this doesn’t work, you can also try disabling any antivirus software or firewall VPN software that could interfere with your Internet connection. You can disable each program by going into its settings and removing it one at a time. After you have disabled all of these apps Try reconnecting to your Internet and see if it remains the same.
If none of these options resolves the problem then you may need to perform a system restore. This will restore your default network settings and will remove any changes that could have caused the issue. This can be done by clicking on «Internet Options» in the Control Panel. Uncheck the boxes that say Use a proxy for your LAN and Automatically detect settings. Keep in mind that this procedure will only affect your current user account so if you’re on the computer of a shared user, you’ll have to repeat this procedure for any other users. You can disable proxy settings with the Registry Editor. However, this method is more complex and could lead to issues in the future.
