Set up your modem using QuickConnect

Before following the steps below, please follow the main setup instructions, including modem placement and whether filters are needed. Before proceeding here, connect your computer to the modem with an Ethernet cable, and make sure the modem is plugged in and connected to the wall jack.


After plugging in the modem, wait 15 minutes for it to install software updates. Then, open any browser on your computer and go to (not "https").

2. In most cases, your identity will be verified automatically. If the system can't do this, you will be asked for additional information.

If the automatic verification isn't successful, you will be prompted to enter the account number shown on your bill or order confirmation email from CenturyLink. Enter that number and your billing zip code, then click "Continue."
