October 11, 2026 I pay for the medium service and I expect faster speeds but I'm getting a whole lot of latency when I try to watch FB or Youtube videos. And it's consistent. Might be time for a change.

Trilight Fiber
September 28, 2026 Trilight internet is excellent. If you ever have an issue a real person answers the phone at Tech Support. They work diligently to solve your problem and if it requires a service call they make the appointment right then. The service technicians, are competent and solve any problems quickly.

KUB Fiber
August 28, 2026 I have had KUB fiber for a little over a year. I live up in the mountains and could not get fiber from another vendor. One major national vendor said they would connect me, but it would cost $6000 because my house is surrounded by concrete patios and a driveway they would have to drill under. So, I ended up going with Starlink. Starlink was OK, but because I live in a forest, sometime getting a good view of the sky was a problem. Then, finally, KUB offered fiber to my area. They connected me for free, even with the obstacles. The service has been great, with almost no interruptions (there have been rare short scheduled maintenance periods), and the speed is 5 to 10 times faster than Starlink at about half the price. On rare occasions I've had tech questions (I run my my own router, mailserver, and nameservice) , support has been great.
