If you subscribe to Xfinity Voice service, connect your telephone to the Tel 1 connection on your Gateway or modem using a telephone cord.

Your Gateway or modem may take up to 10 minutes to be ready to activate. Make sure the lights appear as described below before moving on to the next step. Don't unplug your Gateway or modem during this process.
If you have an Xfinity Gateway with multiple lights on the front, the Power, US/DS, and Online lights should remain solid for at least one minute and the 2.4 GHz and 5 GHz lights should start blinking.
If you have an Xfinity Gateway with only one light on the top, it should remain solid white for at least a minute.
If you have a third-party model, see the manufacturer instructions to see when your modem is ready to be activated.

If you're prompted to enter a PIN instead of a password, click the Connect Using a Security Key link to enter the password in the Security Key field.
