Before moving on, you may try to temporarily disable the third party security programs to check the issue. Go to the following link to see if the suggestions help: Troubleshoot Internet connection problems Is it a domain network or none-domain network? If it is a domain network, it shows unknown status while domain name isn't resolved correctly. Please try to log out domain then join back. Also, please go to check the related internet service and make sure that these services are started: Internet Connection Sharing, Network Connections, Network Store Interface Service.
