Frontier DSL
April 26, 2023 Frontier is okay as an Internet provider but things could be better. I feel like our Internet goes out a lot. It's not for very long but we have to reconnect our devices several times a day and that gets really annoying. I feel like we pay a little more than we used to but our service isn't any better.
