Support XFINITY Internet Securing Your Wireless Gateway Network


Protect your wireless home network from unwanted outside users, viruses and other threats.


If you leave your wireless network unprotected, other people can use your Internet connection, access files on your computers, and even get their hands on private information like passwords and credit card numbers.

What is the Admin Tool Username and Password used for?

If you have a Wireless Gateway or Wireless Gateway 2, it is important that you familiarize yourself with the Admin Tool. The Admin Tool allows you to adjust:
  • Your network settings
  • Your Wi-Fi SSID (network name)
  • Your Wi-Fi Network Key (password)
  • Parental Controls

Logging into the Admin Tool allows you to view or change your home network settings. Every Wireless Gateway and Wireless Gateway 2 comes with the same default Admin Tool username and password. Therefore, Comcast recommends changing the Admin Tool password to further secure your home network. Steps to achieve this are outlined below.
  • Default Username (case sensitive): admin
  • Default Password (case sensitive): password

Note: The username and password that you will use to login to the Admin Tool is not the same as the Network Name (SSID) and Network Key (Password) that you use to gain access to your wireless network.

Change Your Wireless Gateway Admin Tool Password

  1. Open a web browser and enter the web address This will take you to the Admin Tool for your wireless gateway.

    • Note: When attempting to change your network name and/or password using the portal, you must either be using a hard-wired/ethernet connection or you must be connected to your in-home Wi-Fi network (not XFINITY WiFi or XFINITY Home Wi-Fi connections). If you change Wi-Fi settings while you are on your home network, you will lose access to the Wi-Fi session and will need to rejoin using your new network name and/or password.
  2. Enter “admin” in the username field and “password” in the password field.
  3. Click Login.
  4. Click Change Password at the top right.

Change Your Network Name (SSID) and Network Password (Key)

Every Wireless Gateway and Wireless Gateway 2 comes with a unique Network Name (SSID) and Network Password (Key), located on the bottom label. We’ve optimized this information to secure your wireless network, and recommend that you leave this login information unchanged. For more information on how to change your Network Name (SSID) and Network Password (Key), see Wireless Gateway User and Quick Start Guides.

Your Wireless Gateway's Default Security Mode

The default security mode for every wireless gateway is WPAWPA2-PSK (TKIP/AES), which provides optimal security and performance for newer computers. This is a form of WPA security, an advanced mode of wireless security that is extremely difficult to bypass.

PSK stands for Pre-Shared Key, which means you get all the benefits of WPA security without the complicated set-up it otherwise requires. If you have an older computer, you may need to change the security mode to one that is compatible with your device. WPA security is incompatible with some older operating systems. If you don’t use a wireless gateway, you can check your security mode at your router’s administration site.

WEP is an older mode, which is less secure but should work on most computers. If you turn on WEP, you have two choices: 64-bit, which is weaker, and 128-bit, which is stronger. WEP uses a Passphrase, which is similar to the Network Password (Key) used with WPA. Here’s how to change your security mode:

  1. Once you are logged in to the Admin Tool, select Gateway from the navigation bar on the left.

  2. Select Connection, then Wi-Fi from the submenu.
  3. You should see your Network Name (SSID) under the heading Private Wi-Fi Network. Click the Edit button on the far right of the name.

  4. Select WEP 64 or WEP 128 from the drop-down menu next to Security.
  5. Create your Passphrase. For WEP 64, the Passphrase is 10 HEX characters (e.g. 0123456789ABCDEF). For WEP 128, the Passphrase is 16 HEX characters.
  6. Click Save Settings.
