To enable IPv6 on a Frontier router, you need to first log in to your Frontier router. Once logged in, navigate to the Advanced Settings tab and click on Network Setup. Here, you should see an option for IPv6 Support. Select Enabled from the drop–down menu, then save the changes and restart your router. If after following these steps, you are still not able to connect to the internet via IPv6, then contact Frontier customer service for further assistance.
