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.PROS

Earthlink is known for great customer service but higher initial prices
Earthlink’s chief difference from most other national ISPs is that Earthlink is a third-party seller. In other words, Earthlink is partnering with other major internet companies who actually provide the technology for your internet service. Your service through Earthlink might come from AT&T, CenturyLink, Frontier, Verizon, or Viasat. That means your type of connection through Earthlink can vary from super-fast fiber internet all the way to slower satellite internet. You will know which type of internet connection you are purchasing when you sign up for service. Just as with any other provider, you will have an idea of your approximate speed and performance when you buy. The catch is, you will pay more because Earthlink doesn’t own the networks it uses. Why would you choose a service that costs more? Well, Earthlink is known for very solid customer service in an industry that has historically struggled in that area [1]. And Earthlink offers service in less-populated areas without many other providers. That means there may be some places where Earthlink is one of your top options for internet speed or reliability.PROS

CenturyLink Pricing
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.EarthLink Pricing
Earthlink will charge you more initially, but prices even out by the second or third year
Many internet service providers will offer you a great promotional price for a year or two, but then raise prices much higher. Earthlink will not offer you initial promotional prices, so their plans may initially give you sticker shock. For initial prices, Earthlink will charge you more for every type of internet service: fiber, fixed wireless, or satellite. But in some cases, over the course of a few years, you may even end up saving a little money with Earthlink. Only a head-to-head comparison of specific providers in your area will tell you, so check out our price plan comparisons using your zip code.Pricing will also vary significantly based on your internet connection type
The biggest difference between Earthlink plans is whether your chosen plan has a data cap. Earthlink Fiber internet won’t have data caps. Earthlink satellite internet and fixed wireless (4G LTE or 5G) will have data caps. If you have a plan with data caps, you may end up having to buy extra data at the end of the month. Because of these unpredictable charges, satellite pricing and fixed wireless pricing for Earthlink are less stable than for their other plans. But here’s an unusual benefit of Earthlink Wireless Home Internet. Most Earthlink plans require a one-year contract, but Earthlink’s Wireless Home Internet plans do not require a contract [2].CenturyLink Reliability and Performance
“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. Only 65% of CenturyLink’s DSL achieves speeds over 25 Mbps, or what the FCC calls “high-speed” internet. 85% of the CenturyLink DSL network is above 10 Mbps. That means a good 15% of CenturyLink’s DSL customers have very slow connections below 10 Mbps [3]. 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. 28% of CenturyLink customers will get 100 Mbps download, and that speed will considerably improve your performance. But if you are considering ordering CenturyLink DSL, make sure you know what your other options are. You can test your actual speed here to see what kind of performance your current internet connection is giving you.EarthLink Reliability and Performance
Earthlink’s performance depends completely on the networks of major partners
One of Earthlink’s claims to fame is having “the largest network,” because Earthlink serves 90% of the United States [1]. The reality is that Earthlink does have a very large coverage area, but Earthlink does not own the networks in those areas. Differences between Earthlink’s partner networks will mean that your internet speed and performance will vary if you sign up with Earthlink. Just like Earthlink’s pricing, the quality of the service they can deliver depends on other providers. Most of the time, this works out fine because Earthlink partners with reputable ISPs. But Earthlink does not have control over your service, and that can be a disadvantage if something goes wrong. If you get Earthlink Fiber, you are probably going to be happy with your speed and reliability. Fiber is known for these advantages. Earthlink satellite or fixed wireless will often be too slow for real-timeactivities such as real-time gaming or videoconferencing. Reliability issues are going to be more likely with Earthlink’s satellite internet or Wireless Home Internet. Both satellite and wireless internet can be affected by weather. Fixed wireless can also slow down at peak times when thenetwork is congested with more traffic. Satellite internet tends to have high latency, which means a slight lag in the transmission of a signal. Latency is not noticeable for many internet activities but may affect real-time data transfer for gaming and videoconferencing.CenturyLink Equipment, Installation and Bonus Features
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.EarthLink Equipment, Installation and Bonus Features
Earthlink’s installation fees and equipment fees vary
We can't give a score for any kind of consistent pricing or equipment fees because of Earthlink's 3rd party seller business model. Earthlink’s lower rating from us in this category results from the lack of simple, freely available information on pricing and fees on their website, as well as their higher prices for equipment and installation. This lack of transparency is one of the weaknesses of the telecom industry. We recommend that Earthlink, along with other internet providers, begin to be much more straightforward about which services are available across the United States and how much they cost in each area. Satellite equipment will cost you considerably more if you buy it upfront, which is typical of satellite. Earthlink will offer you the option to rent the equipment if that is more feasible. Satellite equipment will come from Viasat, Earthlink’s satellite internet partner. Because Viasat’s equipment fees are $12.99/month or $299.99 prepaid, consumers should estimate that Earthlink’s fees for Viasat equipment will be similar or slightly higher [3]. Earthlink’s bonus services include Easy Tech for unlimited tech support at $9.95 a month. Earthlink Guardian provides parental monitoring, Earthlink Protect gives security protection, and Earthlink Online Backup will protect you from data loss.CenturyLink Experience & Support
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. The American Customer Satisfaction Index confirms that split in results by dividing “CenturyLink” specifically into fiber and DSL. Fiber ranks 16 points higher than the DSL service [4]. 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.EarthLink Experience & Support
Earthlink is known above all for superior customer service
When you research Earthlink online, you will see that Earthlink survives on its customer service. The company gets good, solid ratings for customer service, where many ISPs fall far short. That means that if you call Earthlink, odds are that you will be satisfied with what they do for you. There are just a couple of caveats to that recommendation. First, some customers report that their customer service has been routed to Earthlink’s partner providers, which removes the whole point of having Earthlink service if you’re seeking their brand of better customer service. Second, Earthlink acknowledged beginning to “reshore” its service in September 2021, which implicitly reveals that the company had offshored its customer service [4]. Offshoring customer service to foreign countries is not only potentially frustrating for the customer, but worse for U.S. workers. Many internet providers now base their customer service in the United States, and we hope Earthlink will be sure to provide its own customer support from within the country.CenturyLink FAQ's
