HughesNet Satellite
August 05, 2026 ### One star only because zero isn’t an option HughesNet provided, without question, the worst internet service and customer service we have ever experienced. We remained customers for seven years—not because we were satisfied, but because we live in a rural area and had no other viable option. The service was never consistently reliable. Streaming a complete movie was nearly impossible. Calls repeatedly dropped, including calls made to HughesNet’s own customer service department because the connection was so unstable. When that happened, they wouldn’t call us back, and we often couldn’t reconnect with them to finish resolving the problem. HughesNet repeatedly claimed we had used all our data, even during periods when we had barely streamed anything and hadn’t managed to watch complete movies. We were told that exceeding the data allowance would only result in slower speeds, but what we experienced wasn’t merely a slowdown—the service would become completely disrupted and practically unusable. Technical support was equally frustrating. Technicians would identify problems or recommend solutions, only for HughesNet to refuse to authorize or implement what its own technicians recommended. We spent years calling, troubleshooting, repeating the same information, and being passed around without receiving a lasting solution. We paid every month for a service that frequently failed to provide even basic, dependable internet access. The moment fiber internet finally became available in our area, we left HughesNet. Since switching, the difference has been unbelievable: reliable service, uninterrupted streaming, stable calls, and none of the constant excuses or mysterious data problems we dealt with before. That alone confirmed that our devices and usage were not the real issue. Seven years with HughesNet gave them more than enough opportunity to provide the service and support we were paying for. They consistently failed at both. I would never recommend HughesNet to anyone. If it appears to be your only option, investigate absolutely every possible alternative before signing up. Being without internet may be less aggravating than paying for internet that repeatedly doesn’t work.

XFINITY Cable
June 15, 2026 My internet provider and has consistently provided me with fast speeds. I never have a problem with down loads or streaming. In addition there is never any down time. Even during occasional outages there is always communications from the company. In a short period of time the system is always back up and running.

T-Mobile Home Internet Fixed Wireless
May 16, 2026 I found T-Mobile home internet this year after many years of dissatisfaction with Comcast/Xfinity. So far, it has been a superior service for less money. We've had a couple of blips here and there, but resolved quickly with resetting the wireless router. The router plus 1 booster handles a whole house with about 10 continuously connected devices.

Spectrum Cable
May 11, 2026 My internet provider has done exactly what I expected. The outages have been minimal and short in nature. I've never had a major complaint. When a competitor came in with a way lower offer in our neighborhood, I was going to switch and Spectrum essentially sliced my bill in half just like that. I didn't even raise a stink, they just offered it right away. Great customer service and I'm totally fine with the speed they provide, since we're not very "active" internet users.
