When using Xfinity Voice

The instructions below can be used if you’re setting up Xfinity Voice without Xfinity Internet or if your mobile device doesn’t support the Xfinity app.

Both Xfinity equipment and authorized-owned equipment must follow these procedures. We advise you to look up installation instructions in your manufacturer’s installation manual as well.

Set up your modem or gateway

Locate the cable outlet that is closest to the center of your house.

Place your gateway or modem (don’t put it on the floor) in a space that is open and away from exterior walls, metal objects, microwaves, and windows. Avoid crowded areas and anything that can interfere with a device’s signal.

Connect the power cord to your gateway’s rear and then to an electrical socket.

The Cable In/RF In port on your gateway or modem should have one end of the coaxial cable screwed in and the other end into the cable wall outlet. A finger-tight attachment should be made.

It could take up to 10 minutes for your gateway or modem to be ready to start up. Before continuing, confirm that the lights are as they will be in the following instructions. During this process, don’t unplug your gateway or modem.

The next step is to connect to the internet, either using WiFi or an Ethernet cable.

If your gateway or modem allows for wireless connections, connect through WiFi.

On the side, back, or bottom of your gateway or modem, look for printed information about the Network Name (SSID) and Password. Name variations include Home-XXXX and XFSETUP-XXXX.

Choose the Network Name from the list of available networks in the WiFi settings on your WiFi-enabled device. When asked, enter the password. Click the Connect Using a Security Key link to input the password in the Security Key field if you are asked to enter a PIN rather than a password.
