What CenturyLink is and how it delivers internet to your home

CenturyLink is a regional internet service provider that operates in about 37 states, primarily in the West, Midwest, and South. The company delivers internet through two main technologies: fiber-optic lines (the fastest option where available) and DSL, which runs over existing telephone copper wiring. CenturyLink also owns the Quantum brand in some markets, which offers the same services under a different name.

CenturyLink does not operate in every state or every neighborhood within the states where it does operate. Before you consider signing up, you need to check whether the company serves your address. You can enter your street address on CenturyLink's website to see what speeds and packages are available at your location. If fiber is available in your area, you will see speeds up to 940 Mbps. If only DSL is available, speeds typically range from 10 to 100 Mbps depending on your distance from the nearest equipment hub.

The company bundles internet with phone service and sometimes television, though TV service has been discontinued in many regions. Most customers sign up for internet alone or internet plus phone.

Key Takeaways

  • CenturyLink serves about 37 states but not all neighborhoods within those states, so you must check your address first to see what speeds are available.
  • The company offers fiber internet (up to 940 Mbps) where available and DSL (typically 10 to 100 Mbps) in other areas, with prices and speeds varying by location.
  • Standard contracts run 12 or 24 months, and early termination fees explore if you cancel before the contract ends.
  • CenturyLink charges a modem rental fee each month unless you buy your own compatible equipment, which can save you money over time.
  • Customer service complaints about billing, installation delays, and service outages are common, so read recent reviews for your specific area before committing.

Speed, pricing, and what you actually get for your money

CenturyLink's advertised speeds and prices both depend on what technology reaches your address and what promotions are running when you check. Fiber customers in some markets can get 940 Mbps read speeds. DSL customers typically see 10, 25, 50, or 100 Mbps depending on their distance from the telephone exchange. Prices for fiber packages often start around $50 to $65 per month for the first 12 months, then jump to a higher renewal rate. DSL packages are usually cheaper upfront but offer slower speeds.

The price you see advertised is almost never the price you pay. CenturyLink adds a modem rental fee (usually $10 to $15 per month), taxes, and sometimes equipment fees. If you bring your own modem that CenturyLink approves, you can skip the rental fee, but you have to buy the modem upfront—typically $100 to $200 depending on the model. Over a two-year contract, buying your own modem often saves money compared to renting.

Introductory rates expire after 12 or 24 months, and your bill rises significantly when the promotion ends. Before you sign up, ask what the renewal rate will be after the promotional period, because that is the price you will pay for the rest of your contract.

Contract terms and early termination fees

CenturyLink typically requires a 12-month or 24-month service contract. If you cancel before the contract ends, you owe an early termination fee. The fee amount depends on how much time remains on your contract—it is usually calculated as a per-month charge multiplied by the remaining months. For example, if your contract has 18 months left and the per-month fee is $15, you would owe $270 to cancel.

Some CenturyLink promotions advertise "no contract" or month-to-month service, but these are less common and usually come with higher monthly rates or shorter promotional periods. Read the terms carefully before you commit, because the contract length directly affects how much it costs to leave if you are unhappy.

If you move to an area where CenturyLink does not serve, you may be able to cancel without the early termination fee. You will need to provide proof that the company does not serve your new address. Contact CenturyLink's customer service to ask about this exception.

Installation, equipment, and setup

CenturyLink typically schedules a technician to come to your home and install the service. The installation appointment usually takes one to three hours. During this visit, the technician runs a line from the street to your home (or uses an existing line if you previously had CenturyLink phone service), installs a modem, and tests the connection. Installation fees vary—some promotions include free installation, while others charge $50 to $100 or more.

The modem CenturyLink provides is usually a combined modem-router unit that handles both the internet connection and wireless signal. If you want to use your own equipment, you must buy a modem that CenturyLink has approved for your service type. Not all modems work with all service types, so check the compatibility list on CenturyLink's website before you buy. If you use an incompatible modem, the service straightforward will not work, and you will have wasted money.

Setup typically takes a few days from the time you order to the time a technician arrives. During busy periods or in rural areas, wait times can stretch to two weeks or longer. If you need internet urgently, ask about the current wait time before you sign up.

Common problems and what customers report

CenturyLink appears regularly in complaints to the Federal Communications Commission and in online reviews. The most frequent complaints fall into a few categories: billing surprises (charges appearing that were not explained at signup), installation delays (technicians not showing up on the scheduled date or taking much longer than promised), and service outages (internet going down for hours or days without clear explanation).

DSL service is particularly prone to outages and slowdowns during bad weather or when the copper lines are congested. Fiber service is generally more reliable, but it is not available everywhere. If you are considering CenturyLink in your area, search online for recent reviews from customers in your neighborhood or city. Local reviews often reveal patterns—for example, whether outages are frequent in your area or whether the company's installation team is reliable.

Billing disputes are common enough that you should review your first bill carefully and compare it to what you were quoted. Call CenturyLink's billing department when ready if you see charges you do not recognize. Keeping records of your signup conversation (dates, names of representatives, quoted prices) makes it easier to dispute unexpected charges later.

How CenturyLink compares to other internet providers in your area

Whether CenturyLink is a good choice depends entirely on what other providers serve your address. In areas where CenturyLink fiber is available, it often competes directly with cable providers like Comcast or Charter. Fiber typically offers faster speeds and more consistent performance than DSL, but prices are often similar. If cable internet is available in your area, compare the speeds, prices, and contract terms side by side before deciding.

In rural areas where CenturyLink DSL is the only wired option, you may be comparing it to satellite internet (Starlink, Viasat, or Hughes Net) or fixed wireless services. Satellite has improved in recent years but still carries higher latency (delay) and data caps in many cases. Fixed wireless is faster than DSL in some areas but less reliable. DSL is usually the most stable option if it is available, even if it is slower than satellite or fixed wireless.

Check what other providers serve your address by using a broadband availability map (the FCC's National Broadband Map is free and covers all providers) or by visiting competitors' websites and entering your address. Comparing three or four options side by side takes 20 minutes and often saves you money or gets you faster speeds.

Canceling CenturyLink and what happens to your account

To cancel CenturyLink service, call the company's customer service line or use the online account portal. You must provide at least 30 days' notice, though some contracts require more. If you are still under contract, you will owe the early termination fee unless you may have access to for an exception (such as moving to an area CenturyLink does not serve).

CenturyLink will send you a prepaid shipping label to return the modem and any other equipment you rented. If you do not return the equipment within the important date, CenturyLink charges you a non-return fee, typically $100 to $200. If you own your modem, you keep it—there is nothing to return.

After you cancel, it usually takes a few days for the service to be disconnected. During this time, you should have your new internet service already installed so you do not lose connectivity. Plan your cancellation and new service installation to overlap by at least one day.

Frequently Asked Questions

Can I use my own modem with CenturyLink?

Yes, but only if it is on CenturyLink's approved equipment list for your service type. Check the compatibility list on the company's website before you buy. If you use an unapproved modem, the service will not work. Buying your own modem saves you the monthly rental fee, which typically pays for the modem in 12 to 18 months.

What happens if CenturyLink service goes down?

CenturyLink's service level agreement promises to restore service within a certain timeframe, but the company is not required to refund you for outages. You can request a credit for the downtime by calling customer service, but there is no automatic compensation. If outages are frequent in your area, that is a sign to consider switching to a different provider.

Is there a way to cancel without paying the early termination fee?

You can cancel without the fee if you move to an area where CenturyLink does not serve. You will need to provide proof of your new address and confirm that the company does not serve it. Some promotions also include a trial period (usually 30 days) during which you can cancel without a fee, but you must read the terms to know if yours does.

How long does it take to get CenturyLink installed?

From the time you order to the time a technician arrives, expect one to three weeks in most areas. During busy periods or in rural locations, it can take longer. Ask about the current wait time when you sign up so you know when to expect service.

Why is my bill higher than the advertised price?

The advertised price does not include the modem rental fee, taxes, or equipment charges. These are added to your bill each month. If you see charges you do not recognize, call CenturyLink's billing department right away. Keep records of your signup conversation so you can dispute unexpected charges.
