Best DSL internet providers of 2021 – CNET

Phone line-based DSL service boasts high availability and low pricing, but speeds and overall value can vary. Here are the top providers to look for.
If you’re shopping for internet service in your area, there’s a good chance your local options include phone line-based DSL service. DSL, short for digital subscriber line, is second only to satellite internet in terms of availability, reaching nearly 89% of US residents. Like satellite internet, DSL internet is a great option for rural areas and comes without many of the problems of satellite service, such as high latency and strict data caps. On top of that, if you’re looking for cheap internet service, it’s often a safe bet. 
But if you choose DSL internet service because it’s cheap and readily available, be prepared for underwhelming speeds. While some DSL providers are capable of delivering an internet speed that rivals the low end of cable and fiber-optic connections, less than half of households have access to DSL internet speeds that would actually qualify as broadband internet (25Mbps download, 3Mbps upload). Speeds aren’t likely to improve much in coming years, either, as many providers are investing in fiber lines or other internet types like 5G or in the case of Starlink, low-orbit satellite internet.
Ultimately, the ISP internet connection quality and value of DSL comes down to your location and which internet service provider is available in your area. We’ve compiled a list of the best DSL providers to give you an idea of what to look for — here are the internet options in no particular order other than alphabetical.
Though it’s true 100% DSL service is no longer offered to new customers, AT&T internet is still available to more people than any other internet provider (excluding satellite). Much of that widespread DSL internet service availability is due to its DSL-based copper hybrid service, branded simply as “AT&T Internet,” which spans 96% of AT&T’s coverage area. AT&T Internet will likely not be available in service areas that overlap with AT&T Fiber, however.
You’ll only get one internet plan option with AT&T Internet: $45 per month for whatever the fastest speed is available at your address. One internet connection plan option with varying speeds may sound weird, but it’s actually common among DSL providers, including most listed on this page. The good news is that speeds ranging from 25 to 100Mbps are available in over two thirds of AT&T DSL service areas, with the max DSL speed of 100Mbps available in 40% of the provider’s internet connection footprint. 
At $45 per month ($55 after 12 months) for speeds up to 100Mbps and a monthly equipment fee of only $10, AT&T Internet is a fairly good deal, even when compared to similar ISP plans from most cable internet providers. Watch your data usage with AT&T Internet, though, as going over the 1TB per month limit could result in a $10 charge for each 10GB block needed to compensate for your overage, up to $100.

CenturyLink isn’t available to quite as many people as AT&T, but it does have a broader coverage area with service available in 36 states, compared to 22 with AT&T. A larger coverage area but smaller customer base indicates that CenturyLink operates largely in locations with lower population densities, or rural areas. Broadband speeds can be a challenge to find in rural areas, but CenturyLink offers download speeds of 25Mbps or higher in 64% of DSL service areas, according to the Federal Communications Commission.
Like AT&T, CenturyLink’s DSL service has a single price, but multiple speed options may be available. Opting for a lower internet connection speed, anything below the 80 and 100Mbps plans, could save you some money upfront on installation costs, but other than that, there seems to be no reason as to why you’d want to choose a slower plan when the monthly price is the same. 
CenturyLink is also the only other DSL internet provider on our list that comes with a data cap, but going over won’t have the same costly consequences as AT&T. CenturyLink plans come with a 1TB per month data allowance, but going over won’t result in added fees or throttled speeds. Excessive, frequent overages, however, may violate your user agreement, which could lead to service disruptions down the road.

If you’re interested in DSL for the basic pricing, Frontier DSL internet service is sure to impress. At first glance, Frontier internet service plans are priced about the same as other providers, maybe a bit lower — but then you realize that the equipment fees, including the modem, are included in the monthly price. That’s right, no additional fees for equipment. On top of that, Frontier plans come with unlimited data and no contract requirements. The latter is less impressive, as all providers on our list are contract free, but the unlimited data is a nice DSL internet service standout.
Another strong point for Frontier is that there are three pricing tiers depending on what speeds are available in your area, so you won’t get stuck paying the same price for 9Mbps as someone who is getting 100Mbps. Look to our Frontier review for more information on Frontier plans and pricing.
One caveat with Frontier: consistently low customer satisfaction numbers indicate not all are pleased with the service. A good number of those customer internet service complaints can likely be attributed to slow speeds, as nearly three quarters of households serviceable for Frontier will only be eligible for download speeds ranging from 10 to 25Mbps, according to the FCC. Furthermore, the majority of customers will only have access to upload speeds ranging from 1 to 2Mbps. Still, if you don’t have faster options in your area, Frontier is worth a look for the fair-minded approach to pricing.

Speeds of any DSL provider will vary by location — that’s just the nature of a DSL connection — but you’re likely to get the fastest DSL internet connection possible with Kinetic. Top speeds max out at around 232Mbps — more than double the max speeds of any other provider on our list excluding CenturyLink’s 120 and 140Mbps plans. 
Kinetic Internet 200, which advertises an internet connection speed range of 126-232Mbps starting at $37 per month, is not available in all service areas, but more than half of Kinetic customers will have internet access to speeds of 100Mbps or higher. The same goes for max upload speeds, which are higher than you’ll find among any major DSL provider.
Like Frontier, Kinetic by Windstream plans come with unlimited data and no contract requirements. Equipment is not included, though, and the rental fee will add around $10 to your monthly bill. Even so, it’s still one of the best DSL internet providers if you can get speeds up to 200Mbps or higher for $47 a month (plan price plus equipment). That’s an excellent deal.

These DSL providers all have sizable footprints throughout the US, but lack the speed, value or consistency of other providers to make our list of the best. They’re still worth checking out if available in your area. 
EarthLink established a fairly large DSL network by acquiring or using networks from other providers. DSL internet plans start at $45 per month for speeds around 25Mbps, but pricing and internet connection speeds can vary widely by location.
While Verizon Fios is the flagship of Verizon’s internet service, the ISP does offer DSL service in select areas. The starting pricing for its DSL plan is low at around $25 per month, but speeds any higher than 10Mbps are tough to find.
Wave Capital recently acquired DSL and fiber-optic networks from Frontier Communications in the Pacific Northwest and transferred service to its new brand, Ziply Fiber. Though “fiber” is in the name, the provider still offers DSL service. Plans start at $40 per month, but the download speeds are “variable.”
DSL internet is a common internet option thanks to high availability and low pricing, but relatively slow speeds will almost always fall well short of cable or fiber internet plans. That said, all of the DSL providers on our list offer speeds up to 100Mbps or higher in select areas, which is plenty of speed for streaming in HD and gaming online. Most providers also come with favorable service terms, such as unlimited data or high data allowances, contract-free service and price guarantees.
In most locations, no. Cable typically offers faster speeds and lower cost per Mbps than DSL. Some high-speed DSL providers, such as Kinetic, can deliver speeds that rival low or midlevel speed tiers available from a fiber-optic or cable provider. Additionally, DSL does offer slightly better availability than cable internet, especially in rural areas. 
DSL speeds are like the noise level at a concert. The closer you are to the stage, the louder it will be. With DSL, providers often use fiber-optic or coax cables to run service to local service hubs and from there use a telephone line to carry service to your home. These service hubs are like the stage at a concert. The closer your address is to a provider’s service hub, the faster your speeds are likely to be. This is why residents of more remote, rural areas are often stuck with the slowest DSL speeds. 
Though DSL also uses your phone line for service, DSL and dial-up are two completely different internet connections. DSL uses the phone line differently than dial-up or your home telephone service, enabling an “always on” connection and simultaneous use of your home phone for making calls.
