Wire 3
November 12, 2026 I have been trying for MONTHS to get service from Wire3 and it has been a nightmare. I kept asking for an installation date and today I find out that my property is listed as private property and they need to get permission from someone to install the service. Two things. 1.) Why was I not told that a long time ago, I would have made sure it was taken care of. I have lived here for over 14 years and I am 1000% sure they would not have an issue with me having Wire3 Internet. 2.) I have a wired cable service into my apartment so Wire3 could very easily follow the same line in and I would have service. Why do they need to get permission to do something someone else has already done? I cancelled the installation, not that it matters because I probably would never have receive an installation date anyway.

Blue Stream Fiber
October 16, 2026 Since our Kings Point of Delray switched to Blue Stream there have been daily buffers, loss of channels, problems with turning tv on and finding right way to go to the channels and many other issues. I would never sign up with Blue Stream Fiber again if I had a choice.

WOW
October 08, 2026 I lose internet every single day, and even though it's usually for under 20 minutes, it still means I have to drop my streaming device, close WOW, reconnect, and try to find my stream and start it back up. I don't think that expecting service for 24 hours a day is such a big ask.
