CenturyLink vs. Fidium Fiber Internet Providers Compared

CenturyLink’s DSL internet has wide coverage but slower speeds

CenturyLink is a DSL internet provider owned by a parent company known as Lumen Technologies. Lumen is the seventh-largest ISP in the U.S., based on its combined internet service in both DSL and fiber. Lumen serves a total of about 3 million customers [1]. CenturyLink is the DSL brand owned by Lumen. The fiber brand of Lumen is now known as Quantum Fiber. This review will focus on the CenturyLink DSL half of the Lumen brand. We will cover Quantum Fiber in a separate review, because the two brands provide very different technologies. If your only available internet is CenturyLink, your DSL connection is likely to be slower than if you have cable or fiber. DSL speed can vary widely depending on your neighborhood and even on the wiring in your home. But CenturyLink, like most DSL companies, will charge you the same price for a slow 10 Mbps download speed as for 100 Mbps download speed. It’s luck of the draw, with no price break for slower service. DSL customers just aren’t getting the same kind of value that fiber customers are getting. And that’s one probable reason that Lumen separated its two brands. Now, it should be easy to tell what you’re getting – mostly.  CenturyLink is DSL, and Quantum Fiber is all-fiber. On websites that still mix the two names, though, the speeds of each plan will often be a giveaway. CenturyLink sold half of its DSL network to Brightspeed in 2022. CenturyLink now has a very unusual coverage footprint: think of it as the Western half of the United States, minus California, plus Florida.

CenturyLink DSL charges high prices for widely varying speeds

DSL is not one of the faster internet technologies on the market. Usually, DSL customers sign up for their plans because there is no cable or fiber internet in their areas. And that can be a valid choice if DSL will give you better performance than satellite internet, though you have to evaluate that on a case-by-case basis. Many times, DSL plans are good options for customers in rural areas. CenturyLink plans are no exception to the general qualities of DSL. You will generally pay around $50 for your DSL package, whether you get 10 Mbps download speed or whether you are lucky enough to get 100 Mbps download speed (very unusual for DSL and true for only 28% of CenturyLink DSL customers) [2]. In better news, CenturyLink’s DSL plans are free of data caps. So, despite the fact that CenturyLink’s DSL prices are high for the speeds, at least you won’t have unexpected data overage charges.

Fidium Fiber’s pricing is simple, transparent, and matches other best deals.

Fidium Fiber offers competitive prices across the board, with no hidden fees. Understanding Fidium Fiber's pricing structure reveals significant advantages over traditional cable internet providers, who typically use promotional pricing that increases substantially after 12-24 months. The entry-level plan, currently starting at $/month, offers Mbps download and upload speeds. For families on tight budgets, this is one of the most affordable first-tier plan prices you'll find in the fiber industry. With those symmetrical speeds, you will get very good internet performance for activities like video conferencing. Fidium Fiber's 1 Gig plan, at $55 per month, translates to approximately 5.5 cents per Mbps—among the most competitive rates in the fiber industry. By comparison, entry-level fiber from providers like AT&T or Verizon typically ranges from 10-15 cents per Mbps. Best of all, you will get transparent, straightforward pricing from Fidium Fiber that is much easier to understand than the complex pricing of many other internet service providers (ISPs). Fidium Fiber requires no contracts, no bundling, and no data caps. That means you won't face bills with unexpected overage charges or early termination fees. This customer-friendly policy contrasts sharply with many traditional providers who lock customers into annual agreements with substantial penalty fees. You also won't have the usual $100 installation cost for new internet, as Fidium Fiber offers free professional installation. Fidium Fiber will include the use of a modem/router with your monthly plan price.

“But it was so fast in the ‘90s!” DSL shows its age in many locations

CenturyLink DSL uses one of the oldest internet technologies: copper cables originally designed as telephone wire. About 47% of CenturyLink customers achieve speeds up to 30 Mbps. On the flip side, a lucky 27% are able to achieve 80 Mbps or more, delivering a much better experience [5]. If DSL gives you under 10 Mbps download speed and only 1 Mbps upload speed, you won’t be able to play real-time games online with any kind of reliability. You may also experience glitching if multiple people stream or videoconference at the same time. To be fair, some DSL connections will give you faster speeds. However, if you are considering ordering CenturyLink DSL, be sure to research your other options. You can test your actual speed here to see what kind of performance your current internet connection is giving you.

Fidium Fiber brings the speed and reliability of fiber to new service areas.

Fidium Fiber offers symmetrical speeds ranging from 100 Mbps to 2000 Mbps, depending on your plan. That's great news if you live in a town that hasn't had fiber internet before. According to Federal Communications Commission data, Fidium Fiber currently reaches approximately 1.56 million fiber passings across more than 700 communities in eight states. The company plans to expand to 2 million passings by the end of 2027, with coverage concentrated in the Northeast—particularly Maine, New Hampshire, and Vermont. Secondary markets include Illinois, Minnesota, and Texas, while California, Pennsylvania, and other states have more limited availability. You can call our experts at 1-833-438-0953 to quickly discover if Fidium is available in your area. Fidium Fiber's symmetrical speed delivery represents a fundamental advantage over cable internet technology. The practical implications become apparent in real-world usage scenarios: home-based professionals uploading large files, families sharing content on social media, and households using cloud storage services experience dramatically improved performance with Fidium Fiber compared to cable alternatives. Network latency, a critical factor for gaming and video conferencing, benefits significantly from fiber-optic technology. Fidium Fiber connections typically deliver latency measurements under 10 milliseconds to nearby servers, compared to 15-30 milliseconds common with cable internet connections. This reduced latency creates noticeable improvements in online gaming responsiveness and video call quality. The dedicated nature of fiber connections provides another performance advantage. Cable internet systems share bandwidth among multiple households in a service area, potentially causing speed reductions during peak usage times. Fidium Fiber's infrastructure design maintains consistent speeds regardless of neighborhood usage patterns, ensuring reliable performance throughout the day. Peak hour performance stability makes Fidium Fiber particularly valuable for households with multiple users and devices. Some Fidium Fiber customers have said that they are not getting their promised speeds, but others report being very satisfied [7]. If you have any doubts, you can test your actual speed here to see what kind of performance your current internet connection is giving you.

Option to use your own modem/router or self-install your connection

With the CenturyLink DSL plan, there’s a $15 a month modem/router rental fee, which is on the high end of equipment fees. You can avoid the modem/router fee by buying your own. And that might not be a bad plan, given that you will make up the price of a typical modem/router in a year or less. You may have to pay for a professional installation, which is usually a one-time fee of $99. Fortunately, in many places you may also have the option to self-install for $15. It depends whether there is still a working CenturyLink DSL connection in your home.

Free installation, free equipment loan with Fidium Fiber internet plans.

Several fiber ISPs will offer you good promotional prices and no contracts. They may even offer no data caps, as Fidium Fiber does. But very few ISPs also offer free installation for all their plans. The free installation for Fidium Fiber is a nice touch, meaning you don't have to invest upfront to get Fidium Fiber. Fidium Fiber's installation process demonstrates the company's commitment to professional service and customer convenience. The free professional installation (typically a $199 value) includes a comprehensive setup of fiber-optic infrastructure, extending from the street connection to a complete in-home network configuration. Professional technicians handle all aspects of the installation, including running fiber-optic cables to the optimal location within your home, installing the Optical Network Terminal (ONT) that converts light signals to electrical data, and configuring the Wi-Fi 6 Gateway for optimal coverage throughout your residence. Fidium Fiber will provide you with free use of a Wi-Fi 6 Gateway and a whole-home Attune Wi-Fi app, allowing you to control all your devices. The Wi-Fi 6 Gateway may have equipment rental fees depending on the plan (typically around $10/month for lower-tier plans, with some higher-speed plans including equipment at no additional cost). The gateway represents current-generation wireless technology that provides improved performance for homes with multiple connected devices, offering enhanced capacity for various connections, reduced latency, and better performance in environments with numerous smart home devices, tablets, smartphones, and computers. The Attune Wi-Fi app provides comprehensive network management capabilities that go beyond basic router administration. If you have smart home devices, the app will be especially useful. Users can monitor data usage patterns, set parental controls for specific devices, prioritize bandwidth for critical applications, and troubleshoot connection issues without requiring technical expertise. It's also convenient to have a network management app when you want to adjust your settings without logging into your router. Installation flexibility includes evening and weekend appointment availability, recognizing that many customers prefer installation times that don't interfere with work schedules. The commitment to next-day installation availability in many areas reflects Fidium Fiber's focus on customer convenience and quick service activation. For customers who prefer to use their existing networking equipment, Fidium Fiber accommodates personal router preferences while ensuring the fiber connection delivers optimal performance.

CenturyLink runs below average in some satisfaction rankings

CenturyLink’s customer satisfaction rankings vary widely by region on the J.D. Power survey [3]. In the North Central region, CenturyLink ranks above average. In the West, CenturyLink ranks slightly below average, and in the South, CenturyLink is second from last in customer satisfaction. The North Central and West regions where CenturyLink/Quantum Fiber rank higher are also the regions in which Quantum Fiber provides most of its fiber access. The South only includes one state with fiber internet coverage, which means most of that low customer satisfaction rating is based on CenturyLink’s DSL. According to the American Customer Satisfaction Index, CenturyLink's DSL service scored 62 out of 100 in 2025, which was the same score they received the previous year. For CenturyLink and Quantum Fiber, these customer satisfaction rankings tell the story clearly. CenturyLink’s DSL service is not as likely to please you. However, be aware that there is a certain amount of online cross-marketing between the two companies. So, if CenturyLink says they are able to sell you “fiber” as they seem to imply on their homepage, all that means is that they’re going to send you to a Quantum Fiber plan if your address has fiber availability.

Reviews are high for Fidium Fiber’s customer service and operations.

Fidium has grown substantially from its initial customer base of approximately 123,000 fiber broadband customers at the end of 2022 [8]. With about 1.56 million current fiber passings and plans to reach about 2 million by the end of 2027 [10], the company has demonstrated significant scaling capabilities in its buildout efforts. The customer service landscape has matured considerably since launch. Fidium has earned one of the industry's highest Net Promoter Scores [1,2], indicating the company has successfully addressed many of the operational growing pains typical of new fiber providers. Early customer complaints about installation delays, communication issues, and service inconsistencies have been resolved as the company refined its processes and expanded its workforce. The local technician model continues to differentiate Fidium from national providers, offering more personalized service and a deeper knowledge of regional infrastructure challenges. Customer service quality has become more consistent across markets as the company has standardized operations and increased staffing levels to meet growing demand. Beyond the continued absence of data caps and contracts, Fidium has expanded its customer-focused approach across all service lines. The company's operational improvements have resulted in more reliable installation schedules, improved communication with customers, and more consistent delivery of promised speeds, addressing the specific pain points that characterized early customer feedback. With funding opportunities through the Broadband Equity, Access, and Deployment program [10], Fidium is positioned to accelerate its rural expansion strategy while maintaining the service quality improvements that have driven its high customer satisfaction ratings.
