Restarting your computer and router is the first step to take if you’re receiving the error « Windows could not identify this network’s proxy setting ». This will close all open applications and reset the proxy settings to default. For the majority of users, this should solve the problem.
If this doesn’t work try disabling any firewalls, antivirus software, or VPN software that might interfere with your Internet connection. You can disable each app by navigating to the settings and removing it one at a time. After you have disabled all these apps, try reconnecting to your Internet and see if the issue still occurs.
If none of these solutions resolves the problem then you may want to perform a system restoration. This will restore your default network settings, and erase any changes that may have caused the problem. This can be done by navigating to the Control Panel and then clicking on « Internet Options. » Once you’re in this window and you’re there, uncheck the boxes labelled Automatically detect settings and use a proxy server for your network. Be aware that this procedure will only affect your current user account, so if you’re on an shared computer, you might have to repeat the process for other users. You can also disable proxy settings through the Registry Editor, however this is a little more involved and can potentially create problems in the future.
