Comcast is a nationwide provider of digital communication services including high speed Internet, phone and television. Subscribers to Comcast can purchase one or all services. Subscribers to the high speed Internet service use a Comcast provided modem to access the Internet that comes with default factory settings including a default username and password. If the password has been misplaced or forgotten, reset the wireless modem to set the password to factory defaults.
Locate the "Reset" button on the back of the modem.
Press and hold the "Reset" button for at least 15 seconds.
Release the "Reset" button. The modem will reboot. Your modem is now reset to the factory default settings. The default username is "admin" and the default password is "password."
