If you can't connect to the internet while using VPN, even though Cisco Secure Client says that you're connected, or are having other connection issues, then you should follow the troubleshooting steps below.

• Restart your computer.
• Make sure that your computer is up to date.
• Make sure that you are properly signing into VPN using vpn.ncsu.edu and the correct VPN group.
