Best DSL Internet Service Providers

Depending on where you live, CenturyLink internet speeds may not be anything to write home about. Your download speed can land anywhere from 15 to 140 Mbps or somewhere in between, making it difficult to gauge the true value at first glance. Results from our CenturyLink speed test averaged about 105Mbps download and 97Mbps upload. We will say, no matter what your download speed is, CenturyLink brings something to the table with its unlimited data and lack of contracts.

Plus, the ISP promises to not jack your price up. That’s a unique perk—most internet providers offer a low price for about a year, then your bill goes up.

And when the bill goes up, use our guide to lower your CenturyLink internet bill as much as possible.

You can get a Wi-Fi connection for your home with DSL internet, ut you’ll need to pick up a wireless router. Your DSL modem connects to the router and you’ve got Wi-Fi, friend. Your wireless devices can connect to your internet access.

Now that both CenturyLink and Frontier are both in on this no-contract thing, hopefully other internet service providers will feel the peer pressure. So whichever DSL high-speed plan you choose, you are free to opt out whenever you like without incurring an early termination fee.

So yeah, you get unlimited data, you don’t have to worry about price hikes, and you can leave whenever you want. That sense of security is a rare find with an internet plan.

Almost everybody we talked to before writing our CenturyLink review had something negative to say about its customer service. One user was even ghosted by CenturyLink despite setting an appointment. The internet specialist just never showed up! Talk about poor customer satisfaction.

Nobody wants to go days without an internet connection, and shaky customer service can certainly make that possible.

Frontier offers only one DSL plan, so the variety isn’t the best part. The real game changers are that you won’t need to sign a contract to grab Frontier DSL internet service and you get unlimited data. Nice.

If only other internet service providers followed suit.

When you sign up for an internet service provider, you usually have to commit the next two years of your life as well. It’s like an awkward relationship where maybe you want to break up, but neither of you knows how, so you just keep dating forever. (Just us? Cool, cool.)

Anyway, Frontier doesn’t require an intense commitment from you. You can sign up for any internet download speed that works for you and then cancel if fiber or cable internet finally roll into town. Frontier speed test results are pretty good, too—213Mbps download speed and 185Mbps upload speed. Perfectly comfortable speeds for a small to medium household.

We can't imagine you tearing through any kind of data cap with the relatively slow download speeds you'll get with DSL internet. But not having to worry about overages is a nice relief either way.

While Frontier is available in 25 states, it’s a bummer you can’t get it everywhere. (Don’t you hate it when you read that something is easy on your wallet but you can’t get it in your area?)

Hopefully, this isn’t one of those moments. Frontier is available in 29 different states—so enter your zip code below and let’s see how lucky you are.

Lazily driving along backroads in the country is one of our favorite pastimes, and you can imagine how shocked we were to see a big Windstream sign on a brick building as we slow-rolled through rural Georgia (Windstream is the parent company to Kinetic). But that’s one of the perks with Kinetic: it serves the small towns other ISPs have forgotten.

And not long ago, Kinetic's choices were a bit lackluster. But this ISP has since stepped up its game, offering speeds up to 300 Mbps—or up to 2,000 Mbps, if you’re lucky enough to live in an area with fiber.

Kinetic also offers no-contract options and an unlimited data cap. Most internet service providers only give you 1 terabyte (TB) of data, and it’s nice knowing you won’t get any passive-aggressive emails sent at 2 a.m. warning you that you’ve almost reached your data cap.

Kinetic's prices are low—limbo low. You’ll be hard-pressed to find a provider that comes close, especially when you’re talking triple digit speeds.

As you can tell from the table above, Kinetic's pricing can feel a little misleading. (Sadly, most ISPs are the same story.) After the first year of your contract, expect the price to double. Make sure to ask about the price increase before signing up.

You might assume that digital subscriber line (DSL) is just a fancy term for dial-up, but while both technologies use your phone line to connect you to the internet, that’s pretty much the only thing they have in common.

While good ol’ dial-up means you can’t take phone calls while surfing the web, DSL lets you do both. (Thank goodness, right?)

DSL is also a lot faster than dial-up—and you won’t need to wait for all those beeps and trills before you click on Netscape, err, your internet browser. (Thinking about dial-up has us stuck in the late 1990s.)

But why might you pick DSL over cable internet? Well, DSL is usually cheaper and more widely available than cable, since pretty much every part of the US has phone service. Of course, there are always exceptions to this, but if you’re digging life in the wilderness, you can always check out our picks for satellite internet.

When it comes to DSL internet, we recommend CenturyLink, Frontier, and Kinetic. Here’s a quick look at why these four ISPs earned our vote:

• CenturyLink: Editor’s Choice. Who could say no to CenturyLink’s promises of no price hikes, unlimited data, and no contracts? We sure couldn’t.
• Frontier: Best budget option. With a variety of (slower) speeds, no contracts, no data cap, and low prices, Frontier’s DSL internet is an excellent choice for those who prefer to save money.
• Kinetic: Best rural option. Kinetic makes its home in rural towns where time moves more slowly. Plus, it comes with no contracts, no data caps, and some pretty rad speeds and prices.

Our team routinely conducts speed tests on our own home internet networks and collaborates with folks in other locations to evaluate ISPs and perform speed tests. Additionally, we use a vast dataset made up of Reviews.org internet speed test results gathered nationwide to gain a more comprehensive understanding of typical performance. When users perform speed tests on our website, we store their results in a database, which includes information about the ISP they used during the test. We have amassed millions of data points, allowing us to gauge download and upload speeds across various internet service providers.

To further enhance our evaluation of an ISP, we also rely on external sources such as the American Customer Satisfaction Index (ACSI), HighSpeedInternet.com, and the Federal Communications Commission (FCC), while acknowledging the limitations of FCC data, which may not encompass every ISP.

We also use outside sources like the Better Business Bureau, JD Power, and Consumer Affairs, along with social media sites like Reddit or Quora to get a more comprehensive view.

Long-story short: We balance our own proprietary data and personal experience with research from other sources.
