In this detailed review, we dive into what it’s like using CenturyLink’s 1 Gig fiber internet for over a year and a half. We’ll cover real speed test results on wired and wireless devices, discuss reliability and service, and compare the cost and performance against Cox Gigablast. If you're thinking about switching internet providers, this real-world breakdown will help you decide.
Here are the real-world speed test results across various devices in our home using CenturyLink fiber:
Surprisingly, wireless speeds often outperformed wired in our tests.
In 18 months, we experienced only two outages—and both were caused by nearby construction damage. Each outage was resolved in under 24 hours, making overall service reliability excellent.
| Service | Contract | Download / Upload | Monthly Cost | 18-Month Cost |
|---|---|---|---|---|
| CenturyLink Fiber | No Contract | 940 Mbps / Uncapped | $65 | $1,170 |
| Cox Gigablast | 12-Month Contract | 940 Mbps / 35 Mbps | $99 | $1,782 |
Savings with CenturyLink: $612 over 18 months
After 18 months of use, CenturyLink fiber proves to be a fast, reliable, and affordable internet service. With no contracts, consistent high speeds, and fewer outages than our experience with Cox, we confidently recommend it—if it's available in your area.
Don’t forget to check out our video showing the full installation of CenturyLink fiber, which has over 170,000 views!
We’ve had CenturyLink fiber internet for over 18 months, and in this video, I’m going to share our experience with it—the good and the bad.
The fiber cable that services our home is provided by CenturyLink. We’re on their 1 Gig plan, but actual ISP max speed is 940 Mbps—which is still incredibly fast. This is due to how light travels through fiber cable, and yes, that’s as cool as it sounds.
Our contract guarantees $65/month for life with no increases. Over 18 months, that price has remained unchanged—no hidden fees or hikes.
We’re testing both wired and wireless speeds. For wired tests, we checked:
Wireless speeds using our Netgear WAX630 ranged from 350 to 850 Mbps, sometimes even faster than wired connections.
In terms of reliability, we’ve only had two outages in 18 months—both from construction damage. Both were resolved in under 24 hours.
Let’s compare costs with Cox Cable Gigablast:
Over 18 months, Cox costs $1,782 while CenturyLink costs $1,170. That’s a $612 difference—and CenturyLink wins in upload speed and flexibility too.
We’ve had our share of Cox Cable issues before switching, and based on this long-term experience, we’re happy we made the move. Unless fiber isn’t available in your area, CenturyLink fiber is a smart choice.
