Spectrum Cable
June 11, 2026 Over the years the bill has increased for assorted fees. I understand inflation but we have not gotten anything better as far as service for this increased fee. It is frustrating to see new customer prices when we've been customers for 15 years.

Norvado Fiber
May 18, 2026 Norvado is a local internet service provider that is more affordable than the other options in my area. I am not as pleased with the speed but the price makes it worth using.
Kinsey L
Spectrum Fiber
May 17, 2026 We just moved to Wisconsin last August and had switched over from Optimum to Spectrum. We picked a lower tier plan to save on cost and have had few issues over this past year. After 6 months we did see an increase in our bill by $10 which we weren’t too happy about but are still paying less than we did at our last home. Overall, the service we get for the price is rather fair and fits our needs as a family.
