Our CenturyLink Business Internet review
Lexi is part of HighSpeedInternet.com‘s business editorial team. All reviews are created using provider-sourced data and verified by industry-trained researchers to ensure accuracy.
CenturyLink Business Internet is a wired internet option for businesses, with either fiber or DSL available depending on your location. If fiber is available at your address, you can expect faster speeds and stronger overall performance, especially for things like video meetings, cloud platforms, and large file transfers. If fiber is not built out in your area, CenturyLink also offers DSL, which supports more basic day-to-day needs like email, browsing, and standard online tools. Because availability varies by region, what you can get really comes down to your business location.
CenturyLink keeps its business plans straightforward, with predictable pricing and support available around the clock. Since the service runs over a wired network, performance is generally more stable than satellite or fixed wireless options. In areas where infrastructure choices are limited, CenturyLink is often one of the primary wired providers businesses can consider.

CenturyLink Business Internet bundles and add-ons
CenturyLink Business Internet is generally sold as a standalone service rather than as part of pre-packaged bundles. In some locations, businesses can add Business Voice to their internet service, but availability and pricing depend on the region. Other features, such as security tools or managed Wi-Fi, are offered as add-ons and come with separate pricing rather than being included in a standard bundle.

CenturyLink Business Internet data caps
CenturyLink Business Internet isn’t structured around monthly data limits. Both Simply Unlimited Business Internet and Business Fiber plans include unlimited data, so there aren’t overage charges tied to how much data a business uses in a month.
That means you don’t need to estimate usage or monitor data totals throughout the month. For businesses within CenturyLink’s service area, data limits aren’t something you need to factor into plan selection.
CenturyLink Business Internet fees
Fees can vary depending on the plan, location, and whether a contract applies. Promotional pricing does change after the initial term ends. Before moving forward, it’s worth confirming what charges apply to your service so you know exactly what to expect beyond the advertised rate.

| Early termination | Applies to plans that include a contract. Fees depend on the agreement and remaining term. |
| Installation | Up to $95, depending on service and location. Installation is sometimes waived with promotions. |

CenturyLink Business Internet installation, equipment, and contracts
CenturyLink Business Internet setup requirements depend on whether you choose fiber or DSL service.
Installation
CenturyLink Business Internet installs usually involve a technician, especially for fiber or new service locations. The technician handles the connection and equipment setup. Installation fees may apply, though some promotional offers waive installation fees. Service is active once the install is complete.
Fiber equipment
CenturyLink Business Internet fiber service uses fiber-specific equipment installed on site, typically an optical network terminal (ONT). This equipment connects your location directly to CenturyLink’s fiber network and usually stays in place once installed. A router or gateway may also be included or required, depending on the setup. Because fiber installs are more customized, the equipment is generally provided by CenturyLink and must be returned if service is canceled.
DSL equipment
CenturyLink Business Internet DSL service relies on a standard modem that runs over existing phone lines. The setup is simpler than fiber and may allow businesses to use their own compatible modem in some cases. Depending on the plan or promotion, CenturyLink may also provide the modem. If CenturyLink supplies the equipment, it typically needs to be returned when service ends.
Contracts
CenturyLink Business Internet plans don’t all use the same contract terms. Some plans are offered without long-term contracts, while others may require an agreement depending on the offer and location. If a contract applies, ending service early can result in an early termination fee. Because this varies by plan, it’s best to confirm contract requirements and pricing terms before signing up.
CenturyLink Business Internet vs. the competition
| Provider | Price | Speed | Type |
|---|---|---|---|
| CenturyLink Business | $55.00–$75.00+/mo.* | 3–940Mbps | Fiber or DSL |
| Frontier Business | $69.99–$159.99/mo. | 500–7,000Mbps | Fiber |
| AT&T Business | $70.00–$285.00/mo.† | 300–5,000Mbps (symmetrical) | Fiber |

CenturyLink continues to offer both fiber and DSL business internet, while AT&T and Frontier have shifted their attention almost entirely to fiber for new business sign-ups. If fiber is available at your address, speeds and overall performance are going to look pretty similar across all three providers, especially for everyday needs like video calls, cloud software, and shared online systems.
CenturyLink stands out because it still offers DSL in areas where fiber hasn’t been built out yet. DSL won’t match fiber when it comes to speed or reliability, but it can make CenturyLink a workable option in locations where AT&T or Frontier fiber simply isn’t available.
CenturyLink Business Internet: Our final take
CenturyLink is a practical option for businesses that need wired internet, particularly in areas where options are limited. CenturyLink delivers service over its wired network, offering fiber in select locations and DSL more broadly. Fiber locations have access to much faster speeds, while DSL supports more basic business use where fiber isn’t available.
If you are choosing between CenturyLink DSL and a satellite provider, CenturyLink is usually the better fit. A wired connection does offer more consistent performance and lower latency than satellite. If fiber is available at your address, whether from CenturyLink, Frontier, or AT&T, it is worth comparing plans, speeds, and pricing before deciding. In fiber-ready areas, shopping around can help you find the best long term value for your business.
