Quantum Fiber
April 18, 2025 Quantum Fiber has been a good provider to work with for the past couple of years that I have lived in my current apartment building. I have yet to experience any issues with their service. I wish that the price was lower just so that the service was more competitive with other lower-priced providers, but I receive home Internet reimbursements monthly from my remote job that help to mitigate this cost. I have friends in the city who have experienced severe issues with their Internet providers, so I do feel that Quantum Fiber has gone above and beyond in terms of service in comparison to those other providers. Having no lapse in Internet service is key for remote workers, so this is a huge benefit of working with Quantum.

September 27, 2024 Overall, Xfinity has been a pretty good provider. We have not experienced any outages. My husband and I both work from home and never have issues with speed. I like the interface online. Customer service could be better but overall I am pretty happy with them.
A Seattle, WA Customer
Astound Broadband Fiber
August 11, 2024 It's only $65/month and it's gigabit, so very fast. The provider was really nice in installing quickly and easily, and the setup was remarkably easy. They even wore boot covers in the house and were in and out in under 20mins. We have never had any service interruptions, but that's in part due to being in a big city. We like the fact that internet pricing is competitive where we live, so prices are forced lower than we've experienced in the past - and service must be top notch. We have the option of 3 different fiber gigabit providers, and Astound was just the easiest one to get on site ASAP.

Astound Broadband Fiber
September 25, 2023 Our internet provider was previously Wave. Since being purchased and remarked as Astound, the quality of customer service and speed has decreased. We have been charged with random fees without notice, and are no longer made aware of outages. Planned outages are no longer communicated. It seems as though they do not want to retain their customers. Unfortunate, but we will be seeking a new provider soon.
