AT&T Fiber
January 22, 2026 AT&T has been very good to us. Although their prices can be expensive, the internet is always fast and reliable. We have been getting gig speed and hope to continue with the company. Internet is important in my life so having fast internet is enjoyable. If you are willing to pay, I would recommend AT&T Fiber.

Astound Broadband Cable
January 18, 2026 Overall, I am satisfied with the service. The download speed is fast (1Gbps), and the pricing is fair. The install process and setup was straightforward. However, the biggest downside by far is that the upload speed is much slower than the download speed.

unWired Broadband Fixed Wireless
January 15, 2026 Great customer service. I live in a very rural area and internet services are limited. When I first moved to my current residence I was an existing AT&T customer. To keep things simple I transferred my services. After one year of very slow unreliable service via the phone line I switched to fixed WiFi with unwired. Not only did the internet service improve but the cost decreased. They treat their clients well. When I called in to lower my internet’s speed because I couldn’t afford the current plan they acknowledged that I was a long time customer and decreased my monthly bill but also increased my speed. When their service tech were on site they are polite and respectful. Unwired broadband is a great company to work with.

Spectrum Fiber
January 15, 2026 I've had Spectrum for about 4 years now. Overall service has remained stable with very little downtime. Speeds are also stable for most of the day as well, which is a requirement for work and streaming. Customer service is mostly responsive, although wait times are usually long during peak hours. Pricing is reasonable, although I'd appreciate more clear breakdown of fees and more transparent communication on plan updates.
