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


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


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 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 Password (Network Key) on a label on the side or bottom panel of your device. (The labels differ by wireless gateway model.)
The Default WiFi Settings label lists the Network Names (SSIDs) and the Password (Network Key) for the wireless gateway.
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 Network Name (SSID) or Password (Network Key), you can easily retrieve them by following the steps below. You do not need to factory reset your wireless gateway.

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)
      Admin tool login with two fields to fill out in center screen. One for Username, one for Password, then a LOGIN button at the bottom of the window.
    • 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 wireless gateway user guides at Wireless Gateway Guides.
  3. On the left navigation menu, select Gateway, then Connection and then Wi-Fi.
