CenturyLink vs Xfinity: Side by Side Comparison

Centurylink services broadband Internet, TV, and telephone service to consumers over two primary technologies: DSL and fiber-to-the-home (FTTH).

DSL "piggybacks" on Centurylink’s already-installed phone infrastructure to provide broadband Internet service. DSL networks are widely available and generally less expensive than alternatives since they can use the same wires carrying data^[2].

When considering DSL plans, double-check speed tiers available locally, as they can change.

Fiber, on the contrary, is considered the best internet access. In a Fiber-to-the-Home implementation, the provider provides a fiber optic cable the full distance to your home, leading to better performance. The only issue with Fiber-to-the-Home is that fiber is expensive, such that this type of service is not expanding quickly and usually comes with a higher monthly cost than DSL, cable, or fixed wireless.

CenturyLink subscribers have two options for installing service: self-installation or professional installation.

Installing the service yourself isn't complicated, and CenturyLink provides an install kit. Everything needed to perform the installation, including directions, comes with the self-install box. The task generally be done within a half hour.

Professional installation is necessary for homes that have not been connected to CenturyLink Internet before, or in cases where the subscriber doesn’t have time to configure the settings. Appointments can be made when you order service on the phone.

CenturyLink customers with pre-wired homes who are comfortable following instructions can easily save by doing the equipment on their own.
