If you’re getting the “Windows could not find the proxy settings of this network” error, the first thing you need to do is restart your computer and router. This will close all open applications and reset the proxy settings to default. For the majority of users, this will resolve the problem.
If that doesn’t work, you can also try disabling any antivirus software, firewall, or VPN software that could interfere with your Internet connection. This can be done by going to the settings for each of these programs, and then disabling them one by one. After you have disabled all of these apps, try reconnecting to the Internet and test if the issue persists.
If none of these solutions resolves the problem it is possible to perform a system restore. This will restore your default network settings, and remove any changes that might have caused the issue. This can be done by clicking on “Internet Options” in the Control Panel. Uncheck the boxes labeled Use a Proxy for your LAN and Automatically detect settings. This will only affect the current user account. If you are using a shared computer, you might have to repeat the process for other users. You can deactivate proxy settings using the Registry Editor. However, this method is more difficult and could lead to issues in the future.
