The 3 best modems/routers for CenturyLink


Jun 3, 2021 — 4 min read

CenturyLink may let you rent a modem, but what if you want your own? Learn about compatible modem & router options!

When you sign up for your CenturyLink internet plan, you’ll have the option to either buy or rent your modem and router. While there are some advantages to renting, purchasing your own equipment gives you the most control over your device and saves you the most money in the long run. To help you make the most of your internet plan, we’ve rounded up a list of the best internet routers for CenturyLink internet.

Are you a current CenturyLink customer, or are you considering getting CenturyLink internet at your home? Having a quality modem and router is key to taking full advantage of any CenturyLink internet plan with Wi-Fi. 

Many of the Centurylink-approved modems only support DSL speeds up to 100 Mbps, so customers on faster CenturyLink fiber plans won’t be able to take full advantage of their speeds if they purchase the wrong modem.

What’s the difference? DSL is an internet service accessed through phone lines, which do not support the higher bandwidth you get from cable or fiber, so DSL is often best for 1-2 moderate users who stream, browse and game. It typically hits speeds up to 400 Mbps, depending on the provider and your location.

Fiber will give you much faster speeds up to 1000 Mbps, and with some providers like AT&T or Xfinity, speeds are offered in certain locations between 3000 Mbps and 6000 Mbps. A fiber plan will keep your smart home full of power internet users playing games, video chatting, streaming and more, simultaneously.

What to look for in a CenturyLink compatible modem 

While there are many advantages to buying your own internet modem and router rather than renting, it also requires additional research on your part to find the devices with the best features that also fit your internet plan. Here are a few things to consider when you’re choosing a CenturyLink router and modem:

  • DOCSIS: Data Over Cable Service Interface Specification — otherwise known as DOCSIS — allows data to transfer over existing coaxial cable systems at a high bandwidth. Cable modem DOCSIS usually ranges from 1.0 to 3.1, with the best devices having 3.0 or 3.1.
  • Speed compatibility: When you shop around for internet devices, you must find those that are compatible with your internet plan. For example, if your internet plan has up to 200 Mbps download speeds, be sure to shop around for devices that allow for at least 200 Mbps speeds. Choosing a device with slower speeds means you can’t maximize the internet service you’re paying for.
  • Security: You must have a safe and secure internet connection. After all, a secure internet connection helps to keep your personal information safe. A good rule of thumb is that your devices should have password encryption of at least WPA2 or WPA3.
  • Channel bonding: Channel bonding is a way to maximize internet speed by combining two internet channels simultaneously. The higher your channel bonding, the more traffic and speed it can handle. Devices can often go up to 32×8 channel bonding, meaning 32 downloading channels and eight uploading channels.

Need a faster internet plan?

One of the best ways to improve your internet speeds is to shop around for a better internet plan. That could mean upgrading to a faster plan with your current internet service provider, though it could also mean switching service providers altogether. You can check availability on our site to find the best internet in your area.

The bottom line

Choosing the right internet modem and router for your CenturyLink internet plan is critical for maximizing your speed and having the best overall experience. There are many modems, routers, and modem/routers to choose from, and it can feel overwhelming to choose the right one. While buying your devices instead of renting might be more work to find the right fit, it’s worth it in the long run.
