Support XFINITY Internet Wireless Gateway Username and Password


Find your wireless gateway’s username and password.


If you have the Wireless Gateway 1 (model number TG852G, TG862G, SMCD3DNV or TC8305C) or Wireless Gateway 2 (model number DPC3939), you can use the default username and password to log in to the administration site, called the Admin Tool, and adjust your gateway and home network settings. The Admin Tool offers a range of ways to customize your network to fit how you use the Internet. Settings you can adjust through the Admin Tool include:

  • Your network security settings
  • Your Wi-Fi Network Name (SSID)
  • Your Wi-Fi Network Password (Key)
  • Parental controls

From there you can adjust your security settings to make your device and your network personalized and better protected. Comcast strongly suggests you change the default Admin Tool password, as it’s the same for every wireless gateway and could leave your network open to unknown users. Find out more about network security.

Your Admin Tool username and password is required every time you log in to view or change your gateway and network settings.

Your Default Wireless Gateway Login Information

Here is the username and password for the Wireless Gateway 1 and Wireless Gateway 2 Admin Tool. This login information is different from your Wi-Fi Network Name (SSID) and Network Password (Key), which allow people to connect to your wireless network while keeping unknown users out.

  • Username (case sensitive): admin
  • Password (case sensitive): password

Note: The default Network Name (SSID) and Network Password (Key) can be found on the bottom panel of your wireless gateway. Find out more about securing your network.

Don't Have a Wireless Gateway?

If you have a different gateway or wireless router, look for the default login information on your device or manufacturer documentation. Remember that this login information is often case sensitive. We suggest you write down your wireless router password.

Adjust Your Settings on the Router's Administration Site

Now you can use the router username and router password to log in to the router’s administration site – simply open a web browser and enter the URL. Find the Admin Tool login page at
