AT&T Fiber
June 13, 2026 When we started two years ago with the service, it was less than $70. Now we are paying almost $110 for the same service. I will say my speed is wonderful. I can honestly say that I also have very little issues with my service.

Cox Fiber
June 01, 2026 COX provides stable service but lacks severely in customer service. COX service representatives do not disclose to customers that prices are initially discounted and will increase after an initial period. Second, customer service agents are not well equipped to help with customer difficulties in setting up COX modems. The first agent contacted after a few hours of personally attempting to troubleshoot wanted to send a technician that would cost. Another agent after was able to fix the issue within five minutes. These points would not necessarily fully dissuade me from choosing COX, but if I was given a choice (my current unit could only connect with COX), it would certainly factor in when choosing a service provider.
