Customer Reviews for Internet Service Providers in Illinois
Customer Reviews
An Illinois Customer
AT&T Fiber
February 14, 2026 I work from home, so I rely on having a stable internet connection throughout the day. Unfortunately, sometimes connection will randomly cut out. It can last a few seconds, minutes, or at worst, a few hours. Of course, sometimes there are legitimate reasons like weather-related events. However, a lot of the time we don't get a reason at all. It can be very frustrating to be in a meeting with a client and my connection goes out. When the internet does work, it is pretty fast. I've never had issues loading a website or an image or anything for work. My connections over zoom don't cut out or anything, so I am satisfied with the speeds.

May 19, 2023 I was initially satisfied when I first got the provider. The rate was fair and I was happy with my internet speed. The next year the price shot up to almost twice the price. It felt unfair to me since I don't think I am receiving a service that would equal the cost. I have also been having issues with my internet speed lagging and shutting off.
