AT&T Fixed Wireless
March 21, 2026 AT&T wireless is not a very reliable internet provider. Their rates are among the highest in the area. The company offers unlimited access each month but often sends warnings that we are consuming too much bandwidth and will have our speeds throttled back. This is very misleading as a service provider and leads to much dissatisfaction in the company.
Tracy C.
Spectrum Cable
March 19, 2026 Spectrum started off as an affordable option, but over time the prices have increased significantly. The service experiences frequent outages and the internet speeds often fall short of expectations. Overall, it's no longer a good value for what you're paying
