CenturyLink Compatible Modems

About

CenturyLink is a major internet service provider operating across 16 states, delivering both DSL and fiber-optic internet to residential and business customers. In most metro markets, CenturyLink's fiber service is now branded as Quantum Fiber, offering symmetrical upload and download speeds over a pure fiber-optic network. In areas where fiber has not yet been deployed, CenturyLink continues to provide internet over its legacy DSL copper telephone infrastructure. All CenturyLink plans are contract-free with no data caps on fiber and no early termination fees. The provider also offers a Price for Life guarantee on fiber plans, meaning your monthly rate stays locked in for as long as you maintain service. These consumer-friendly policies make CenturyLink a competitive option in the broadband market, especially for customers in its fiber footprint.
