Support XFINITY Internet Find and Change Your Wireless Gateway Network Name (SSID) and Password (Network Key)


This article explains where to find or change your WiFi Network Name (SSID) and WiFi Password (Network Key).

Note: If you do not have a wireless gateway device, see Retrieve Your WiFi Password to learn how to retrieve the username and password for your router.


The following steps apply to the wireless gateways from Comcast:

  • Wireless Gateway 1 (model number TG852G, TG862G, SMCD3DNV or TC8305C)
  • Wireless Gateway 2 (model number DPC3939)
  • Wireless Gateway 3 (model number DPC3941T or TC8717)

Every wireless gateway has a unique, preset WiFi Network Name (SSID) and WiFi Password (Network Key). You will need this information to connect WiFi-capable devices to your secure home network.

You can find your default WiFi Network Name (SSID) and WiFi Password (Network Key) on a label on the side or bottom panel of your device. (The labels differ by wireless gateway model.)
This is an example of a Default WiFi Settings label

Note: If you have a Wireless Gateway 1, you will only see one Network Name (SSID).

If you have changed the default information and no longer have the new WiFi Network Name (SSID) or WiFi Password (Network Key), you can easily retrieve them by following the steps below. You do not need to factory reset your wireless gateway.

Note: Unlike a wireless gateway, if you have a router and have changed or forgotten your WiFi password, you’ll need to reset the device to its factory default settings. This will erase your settings, so you will need to reboot all devices connected to the router in order to re-establish Internet access.

How to Find or Change Your Customized Network Name and Password

  1. Choose a laptop or WiFi device that is currently connected to your network. If none of your devices are connected, use an Ethernet cable and connect a computer or laptop directly to your wireless gateway.
  2. Open a web browser and go to the Admin Tool ( - this is the wireless gateway's administration site. The default settings are:
    • Username: admin
    • Password: password (case-sensitive)
  3. Click LOGIN.
    Admin tool login with a field for Username and Password in the center of the screen.
    • Note: If you changed your Admin Tool password previously, you will need to use your new login information. If you don’t remember your Admin Tool password, you will need to factory reset your wireless gateway. Instructions on how to do this can be found by reviewing the reset information in Comcast-Supported Routers, Gateways and Adapters.

  4. On the left navigation menu, select Gateway, then Connection and then Wi-Fi.

    • On this page, you can also edit your wireless network information, including changing your WiFi Network Name (SSID) or WiFi Password (Network Key). If you make any changes, remember to click SAVE SETTINGS.
