    Verified Customer Reviews

    EarthLink is absolutely amazing! Anytime I have any sort of issue (which is rare) the issue is immediately addressed and solved! I would recommend EarthLink to anyone!

    — Dawn Google Reviews

    I'm very happy and have been for 22 years of using Earthlink. When you need help, that's when Earthlink really shines. Recently I needed help and Brian took my call. He guided through a new way for me to solve my issue. He stayed with me until I fully understood what to do and tested it a few times.

    You'll not find a more knowledgeable and caring customer service group.

    I am very happy with my EarthLink internet. AT&T was going to raise my prices because I had been with them for a year so I switched my highspeed internet to EarthLink. It was installed in February and I have been happy with it since.

    I did have an issue with one smart TV furthest from my modem freezing up. I called up customer service, they ran some tests, then sent me a WIFI extender that resolved my issues and my internet is working better than when I was with AT&T. Service I NEVER received from AT&T. Thank you EarthLink for the great service!
