Support XFINITY Internet About the Wireless Gateways

Introduction

The wireless gateways from Comcast provide the functionality of a Wi-Fi router, DOCSIS 3.0 cable and voice modem in a single device.

What Can the Wireless Gateways Do?

  • Create a secure wireless home network and connect your computers, laptops, and other Wi-Fi electronic products (such as game systems, tablets or mobile phones). With a wireless gateway you can also connect up to 4 products using a wired connection.
  • Connect 2 phones (or a phone and fax) to the wireless gateway, if you subscribe to 2 lines with XFINITY Voice service.
  • If your computer or Wi-Fi device supports Wi-Fi Protected Setup (WPS), you'll be able to set up a wireless network connection quickly with the press of a button.
  • The wireless gateway also handles advanced functions such as:
    • Firewall
    • Parental Controls
    • Port Forwarding
    • Port Blocking
    • Diagnostic Tools

To learn more about the advanced features of the wireless gateway, see Advanced Wireless Gateway Features.

Does Comcast Offer More Than One Kind of Wireless Gateway?

Yes, there are 3 generations of wireless gateways from Comcast.
To learn about the differences between the wireless gateway features, see The Different Wireless Gateways for Your Home Network.

Admin Tool

The Admin Tool is used to customize your wireless gateway to fit how you use the Internet and your network. From a computer or device connected to the wireless gateway, open an Internet browser and access the Admin Tool at http://10.0.0.1. You can customize settings including:

  • Wi-Fi Network Name (SSID) and Password
  • Parental Controls
  • Network Security Settings
To better secure your home network and configuration, it's a good idea to log in to the Admin Tool and change your Admin Tool Login password (since every wireless gateway has the same default Admin Tool Login password). Keep in mind that the Admin Tool password is not the same as your Wi-Fi Network password (Key).

Note: The username cannot be changed and will always be "admin."

See Securing Your Wireless Gateway Network to learn how to change your Admin Tool password or to learn more about how to secure your wireless gateway network.

Default Wi-Fi Network Name and Password

Every wireless gateway has a unique, preset Wi-Fi Network Name (SSID) and password for maximum wireless security. You can find your default login information on the side or bottom panels of your wireless gateway as shown in the sample label below.

Note: If you'd like to change your Network Name (SSID) or password, you can find the instructions in Wireless Gateway Network Name (SSID) and Password (Network Key).
This screen shows Default WiFi Settings. There are 2 windows to enter information in the middle of the screen. The top is Network Name (SSID) and the bottom is Password.

Wired Internet Connection

You can connect the wireless gateway to computers using a standard Ethernet cable. Simply plug an Ethernet cable into one of the 4-Gigabit Ethernet ports, located on the back panel of the wireless gateway.

Each of the ports has 2 LED indicators that indicate the traffic speed.

  • Green indicates 1000 Mbit/s (Gigabit Ethernet).
  • Orange indicates 10/100 Mbit/s (Fast Ethernet).
    Image shows four Ethernet ports, with one green indicator and one orange indicator.
