Internet-only customers, you may be able to order a new modem online.
Here's how to check: Sign in to My CenturyLink and find "My Internet" under the Home tab or the Services tab. Then look for an "Upgrade Modem" link to go to online ordering. If you don't see the link, you can't order online at this time, but you may still be eligible for an upgrade. Call or chat and an agent will help walk you through the process.
