Quantum Fiber
February 22, 2026 I am overall satisfied with the service provided by Quantum and am very happy with the price, it's a third of the price we were paying our previous provider. However, there have been several times when our internet service has gone down and I find it hard to get information on why or what is happening. There is an outage map on their website but it doesn't give detailed information like how long the service interruption is expected to last. There has been just one time that service was down for several days, and they did offer a credit for the following month's service charge which I very much appreciated. Despite the outages we've experienced I definitely prefer the fiber optic service because it's much faster than cable and we get better wifi service throughout our entire two story house.

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.
