Spectrum Cable
April 19, 2023 Spectrum is the predominant service provider in my area. My plan provides up to 1 gigabytes of downloading speed with just 49.99 dollars per month for the first 24 months of installation. I am very satisfied with its speed and consistency. I never had an issue with accessing internet from home thanks to Spectrum. I would highly recommend it to others.

AT&T DSL
March 24, 2023 Overall it's not terrible service considering my previous provider. The internet has a steady download rate, although not the rate I pay for. Still the speed is sufficient to do what I need. Sometimes my speed will increase to the advertised speed I pay for but that is rare.

Spectrum Cable
January 29, 2023 Overall, the service has been good with occasional loss of service. The second time that I set up service was a hassle. I was charged an installation fee even though I self-installed the product. It was frustrating because I never had this fee the first time I set up service. Also, it is frustrating that Spectrum is the only provider in the area, so I must pay whatever they list as the cost of internet.
