Charter Communications offers broadband Internet to consumers over a hybrid fiber coaxial (HFC) network.

Hybrid Fiber Coaxial is a broadband infrastructure that uses fiber optic cables for the network backbone, but switches to lower-bandwidth copper cables during the “last mile” between subscribers.[1] Local "optical nodes" switch optical signal into electric data, which is generally distributed via existing cable television networks.

This kind of connection is widely reffered to as “cable” since they rely on coaxial networking, which is also used to deliver “cable TV.”

CenturyLink's TECHNOLOGY

Centurylink provides Internet, TV, and telephone service to consumers over two main technologies: DSL and fiber-to-the-home.

DSL leverages Centurylink’s already-installed phone lines to provide Internet. While DSL networks don’t offer the fastest speeds, they are widely available and usually more cost-effective than alternatives since they can transmit data via the same lines carrying calls.

When you are evaluating DSL services, verify the speeds available in your area, as they can vary quite a bit.

Fiber-to-the-home (FTTH), on the other hand, is considered the next generation of internet access. Using Fiber-to-the-Home plans, CenturyLink connects a fiber line directly to your home. The main problem with Fiber-to-the-Home services is that installing fiber optic cables is costly, with the result that fiber is not widely available and usually comes with a higher monthly cost than DSL, cable, or fixed wireless.


Charter Spectrum installation is overall straightforward. Most Charter plans are cable, which will require connecting a cable WiFi gateway into the television outlet in your house.

For subscribers with working wiring, self-installation can be done using equipment and self-install instructions charter provides. Homes without Charter wiring or with a need to upgrade will require assistance from a certified technician.

Installation requires a fee. For customers unsure about installing equipment themselves, the fee is likely well worth it for ease and simplicity's sake.


CenturyLink customers have two installation choices: self-installation or professional installation.

Self-installation is relatively straightforward, particularly for DSL. All equipment to complete the installation, plus instructions, comes with the welcome package. The task should be done within half an hour.

Professional installation is needed for homes that have never been connected to CenturyLink Internet before. Appointments with a professional technician can be made when you confirm your order.

There is a bill for professional installation, so centuryLink subscribers with wired homes who are okay with following simple instructions can save money by installing the equipment on their own.

The battle for better service

Customer service matters, and not all online reviews can p trusted

When you find yourself in an area where both broadband providers offer interchangeable speeds and pricing, customer service might be the most important factor to consider. Broadband internet and phone service in particular are vital for emergencies and communication, and having a company that will respond quickly to service issues makes a huge difference.

That said, figuring out which online reviews of a provider’s customer service can be tricky. Look for two key phrases: “IP verified” and “ACSI.” IP-verified reviews use sophisticated network-detection protocols to ensure that each person leaving a review is a unique user on a computer actually on a given provider’s network. Additionally, safeguards are put in place to stop anyone from leaving a review twice, cutting out review manipulation. Ratings throughout BroadbandNow are IP-verified.

ACSI stands for the American Customer Satisfaction Index, a nationwide benchmark for customer satisfaction in the US. Experts at ASCI survey customers manually to ensure the most accurate results.

Reading the fine print

ETFs, hidden fees, and other “gotchas” to watch out for

Centurylink and Charter Communications, like most broadband providers, will often make special “sign-up promotions” to encourage new customers to sign up, and preferably bundle multiple services from their company. These promotional prices can save consumers money, but shoppers have to be careful about a few things.

First, ETFs, or “early termination fees,” could cancel out your savings if there’s a chance you’ll need to switch locations or providers in the near future. Second, surprise fees often show up on broadband bills, and it’s always worth calling your provider and complaining (or at least asking for an explanation) if you see fees that weren’t mentioned when you signed up. Third, be careful to factor in the final monthly price when comparing plans, not just the reduced sign-up promotion or bundle deal. Promotions usually time out within the year, leaving you with a bill that might be higher than you bargained for.
