Spectrum Cable
July 06, 2026 Spectrum is slow, has poor customer service and also has a monopoly in my area. There is no competition. 5G internet service is not available as there is very poor cell signal at my home. Additionally, Verizon began running FiOS to my neighborhood and then stopped. I can only guess because Spectrum holds the cable franchise rights in the town of Glenville and is fighting to hold on to whatever market share they have.
