Best Routers for CenturyLink and Quantum Fiber: How to Choose

CenturyLink: “The modem must have a certain configuration to work with our service. We can’t provide a list of third-party modems that could work because there are hundreds of brands and models available, and we can’t guarantee any of them to be set up correctly.” It adds that a modem must be compatible with both the connection type and the speed of the service.

Quantum Fiber: “We are unable to provide a list of non-Quantum Fiber equipment because we can’t guarantee any outside modem will be configured correctly to work with our service.” It also separates the two pieces you need: a SmartNID or modem, and Wi-Fi equipment. On the second piece it says you do have the option to use a Wi-Fi solution of your choice, while recommending its own.div>

CenturyLink or Quantum Fiber: what is the difference?

This is the other question the page gets, so here it is in one place.

CenturyLink is the wider brand. It covers legacy DSL service as well as fibre. That is why its support pages talk about matching a modem to a connection type and a speed.strong>Quantum Fiber is the fibre side of the same company. On Quantum Fiber, the modem is provided at no cost, It comes in one of two shapes. It is either a stand-alone gateway such as the C4000XG, or a permanently mounted SmartNID such as the C5500XK.p>

Two details are worth knowing before you plan anything. Customers who joined before 18 February 2022, in a listed group of states, may find that their Quantum Fiber modem can also work as their Wi-Fi router. And the 360 WiFi pods that Quantum Fiber offers are not WPS compatible, so pairing by WPS button will not work with them.

What was corrected on this page, and when

This page was rebuilt on 28 September 2026. The previous version carried twenty-four exact prices and more than one hundred affiliate links. It had no internal links and no primary sources. It framed the choice as buying a modem for CenturyLink, when both CenturyLink and Quantum Fiber supply the modem and state that no third-party list can be given.Every price and affiliate link was removed and replaced with verified models, and the providers’ own wording now appears on the page.
