CenturyLink is one of the leading Internet Service Providers (ISPs) offering low-cost and fast internet services with speeds of up to 1Gbps. It has a wide range of modems and routers suitable for different applications. You can also replace your CenturyLink internet modem with any compatible modem if you are not satisfied with the one that came with your service plan.

Things to Remember Before Replacing Your Modem

There are a few things that you should keep in mind before opting for a third-party modem. CenturyLink uses different modems and routers depending on the type of connection (fiber, DSL), speeds, and location.The CenturyLink customer service representative will recommend the ideal modem for you by default. But you can opt for a third-party modem. In that case, the CenturyLink service technician will not be able to install it for you, and CenturyLink will not facilitate any modem returns.

If you require professional assistance with the installation, you will need to use a CenturyLink modem. However, you can get a third-party modem later and send the original one back to CenturyLink. You will need to contact CenturyLink customer service to initiate the modem return process.

Choose a Compatible Modem

Since technology continuously evolves, modems and internet services also undergo frequent updates, rendering the old equipment obsolete. Also, the kind of equipment varies depending on the area and the service. We recommend using a certified and tested CenturyLink modem to avoid hassle and compatibility issues.
