I was having a hard time connecting to the Internet in my apartment. I decided to go with EO Internet service. I followed the instructions on the web but kept getting an error on my Airport Time Capsule about IPv6. I was able to connect the Internet to my laptop but I couldn’t connect from any of my phones. It turned out I had to enter the IPv6 DNS addresses in the Airport Time Capsule. I used the DNS service from Google. It worked.
