Can I use my own router/modem with CenturyLink service?

When you order online, you will see a note during the order process if bringing your own modem is an option. However, if you have CenturyLink internet service, you will get the best experience and performance by using certified CenturyLink equipment. Why? Our modem/router combo equipment is tested and guaranteed to be optimized for maximum performance, is easy to set up, and come with free 24/7 tech support. You can purchase or lease a compatible modem from CenturyLink to use with your service.

What's the difference between a modem and a router? Do I need to have both?

A modem is the equipment needed to bring internet service into your home over a wired connection (meaning you would plug your computer into the modem directly). A router is what allows you to access that internet connection through WiFi. So most customers do need a router in order to access their connection from all of their wireless devices. 

The good news is that the equipment provided by CenturyLink is a combination modem/router in one easy-to-use unit (we also refer to this unit as a "residential gateway").
