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.

Other CenturyLink-compatible equipment

If you are interested in other CenturyLink-compatible equipment, CenturyLink has a list of all approved internet equipment on its website. These modems and gateways have been tested by CenturyLink and are 100% compatible with all CenturyLink plans.

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 internet availability to find the best service 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.
