NextLight Fiber
February 18, 2024 We subscribe to our city's fiber internet service. I can't remember for sure now, but I believe we were one of the charter families in the service. We subscribed early enough that we get discounted pricing for the 1-gig service. At the time the service rolled out, it was the only community-based and community-owned fiber service in the country, so it was great to see tech magazines following the story and confirming that we were not only getting something cutting-edge, but also something that would be more stable than what the national telecom companies like Comcast were offering in the area. We have very little downtime with it and have found the support team to be amazingly responsive, since they're local. My only frustration is that my devices don't run internet as fast as the service provides because of their age. I'm not getting my full money's worth at the moment, but that's my issue to deal with and not NextLight's!

Zentro
September 18, 2026 Awful install experience, weird service, lax security and complicated setup. My building is forcing everyone to use Zentro and the entire building hates them. Previously we were forced to use Xfinity and despite their awful reputation, they have become the hero of this story, and all of the building wishes we still had them. Definitely wouldn't recommend Zentro, not even to an enemy.

July 10, 2026 Internet service is good most of the time. Spotty sometimes. The install was a nightmare and continues with neighbors getting installs while the main box is in our yard. The installers continue to break up our landscaping, edging, and will not replace or repair. Called main office and got no help there at all. Had to call a technician to come out once and he was no help at all.
