About Your Wireless Gateway
The XFINITY™ Wireless Gateway is the next-generation cable modem and Voice-Over-IP (VoIP) adapter,
integrated with home gateway features. It combines a two-line Embedded Media Terminal Adapter with an
integrated WiFi router and four wired Gigabit Ethernet RJ45 ports for multiple device connection. Your
Wireless Gateway has been designed to meet DOCSIS®3.0 specifications.
Here’s what you get
...when you subscribe to both XFINITY Voice and Internet services:
•WiFi Technology — WiFi uses radio frequency to connect computers and other devices to a network
without wires. Your Wireless Gateway can connect to b, g and n clients simultaneously.
•Fast Download Speed — Your Wireless Gateway is DOCSIS 3.0 compliant with speeds up to eight
times faster than DOCSIS 2.0 cable modems.
•Easy Connectivity — Connect any WPS-compatible computer or device with just one button.
•Security — Because WiFi networks send information over radio waves, signals from your wireless
network can be intercepted by unauthorized users. Use the simple Home Network Wizard to securely set
up your WiFi broadband connection for WiFi enabled devices.
•Convenience — Simultaneously use four Ethernet ports for wired devices and 802.11b/g/n connectivity
for wireless devices. Choice between wireless LAN (WLAN) or wired Ethernet LAN connections.
•Flexibility — the ability to support two lines of telephone service, as well as high speed data; the ability to
use your existing router with your Wireless Gateway.
•Telephony Services — Complies with PacketCableTM 1.5
•Protection — Lithium Ion battery back-up (included with XFINITY Voice subscription)
Note: !If you haven’t already done so, please activate both XFINITY Voice and Internet
!services if you subscribe to both, or just XFINITY Internet services if you subscribe
!only to high-speed data services. Refer to the user guide you received with each of
!these services for activation instructions and information about XFINITY Voice and
!Internet features.

SETTING UP WIFI CONNECTION FOR WPS-COMPATIBLE COMPUTERS
•WPS (WiFi Protected Setup) lets you easily set up secure WiFi networks without entering a Network Key.
•Most WPS-compatible devices will work with your Wireless Gateway. You can easily connect to your WiFi
Network using either the default Push Button Configuration (PBC) or the Personal Identification Network
(PIN) method. Both methods are described below.
•If you aren’t sure if your computer supports WPS, look for a WPS sticker or label
(Fig.1) on your computer or device. If none is found, your computer is probably NOT
compatible with WPS. In this case, follow the steps under WiFi Connection.
WPS via PBC Connectivity/One Button Connectivity (Recommended)
1. Press the WPS button on your computer or wireless device. (If your
computer doesn’t have a physical button, refer to your computer’s user guide
to enable WPS.)
2. Within 2 minutes, press the WPS button on the top of your
Wireless Gateway. (Fig. 2)
3. After a message displays that the connection was successful, your
computer/device is connected to your home network.
Note: !When the WPS button is pressed, it will stay lit for 5 minutes
!!(regardless of whether or not the connection was successful).
!!Please wait until the light turns off before retrying or connecting another
!!WPS device.
WPS via PIN Connectivity
1. Open your computer’s WPS utility and acquire a PIN number. Make a note of the PIN number. The WPS
utility will begin its countdown to 2 minutes.
2. Launch your web browser and type http://10.0.0.1 in the address line.
3. Log in using admin as the username and the password you created in the Home Network Wizard.
4. Select Gateway > Connection > WiFi.
5. Before the WPS Utility finishes its countdown, enter the PIN number from Step 1 above in the
Enter Wireless Client’s PIN field.
6. Click PAIR WITH MY WIFI CLIENT.
7. Your computer will communicate with your Wireless Gateway and establish a
connection.
Note: !If your WPS client prompts you to enter the Wireless Gateway’s PIN during the WPS Connection,
!!enter the WPN printed on the label on the underside of your Wireless Gateway.
