Glo Fiber
January 20, 2026 I previously had Xfinity and they were horrible. Service was decent but so costly. They were the only provider in town so we all had to use them. Then Glofiber came in. Pricing is better than Xfinity. Service is somewhat the same but I do experience some lags when using the wifi. The installation was poor. Was told they would be here one day and they no showed. Then came and did a temporary setup and left a cord strewn across the lawn for days. The installer came and was not friendly at all. He did a poor job of drilling the hole in my wall, left the piece crooked and left all the remnants from the drilling on the floor. Was very short with me and gave me an extra piece of equipment that I never ordered. He didn't verify anything with me before he left and didn't explain any of it to me.

February 16, 2023 Overall, our internet service is pretty good, however it will suddenly drop for brief moments of time. When the internet drops out it's very disruptive because I work from home so a stable internet connection is really important to me. The price is also a little expensive, but the speed is very good and I'm able to conduct video calls and conference calls. Also, when the internet drops it interrupts our cable connection if we're using the cable box to watch things on demand or using a video streaming service like Netflix or Amazon Prime.

April 24, 2026 The process of actually getting the wifi box was an incredibly drawn-out process with Verizon that took over a week of back and forth. The customer service operatives were either incapable of helping or unwilling to assist over the course of 15 phone calls. They forgot to send the wifi box until another call prompted them to look and then had to same day ship it in order to save face. The wifi itself works fine, but it almost wasn't worth the hassle of actually getting it to the house.
