Restarting your computer and router is the first step to take if you’re receiving the error message « Windows could not identify this network’s proxy setting ». This will close all active applications and reset proxy settings to default settings. For most users, this should resolve the problem.
If this doesn’t work, you can also disable any antivirus software or firewall VPN software that might interfere with your Internet connection. You can do this by going to the settings for each of these apps and then removing them one at a time. After you have disabled all of these apps, you can try reconnecting to the Internet and see if the problem persists.
If none of these methods solves the issue, you might want to do a system restore. This will restore the default settings for your network and eliminate any other changes that might be creating the issue. This can be done by clicking « Internet Options » in the Control Panel. Uncheck the boxes labeled Use a Proxy for your LAN and Automatically detect settings. This method only affects the current user account. If you’re using a shared computer, you might need to repeat the process for other users. You can turn off proxy settings with the Registry Editor. However, this method is more complex and could lead to future problems.
