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, it is important that you familiarize yourself with the 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 You can customize settings including:

  • Your network settings
  • Your WiFi Network Name (SSID)
  • Your WiFi Network Key (password)
  • Parental Controls

Logging in to the Admin Tool allows you to view or change your home network settings. Every wireless gateway 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 WiFi Network Name (SSID) and WiFi Network Key (password) that you use to gain access to your wireless network.

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

Every wireless gateway comes with a unique WiFi Network Name (SSID) and WiFi 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.

If you'd still like to change your WiFi Network Name (SSID) or password, see Find and Change Your Wireless Gateway Network Name (SSID) and Password (Network Key).

Your Wireless Gateway's Default Security Mode

The default security mode for every wireless gateway is WPA/WPA2-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.
