How to Login to a Comcast Modem

Click "Start" on the computer plugged in (or connected through a router or switch) to the modem.

Step

Click "Programs" and open your Internet browser of choice.

Step

Enter "http://192.168.100.1/" in the browser's address bar. This is the access address for most Comcast modems. Try "http://10.1.10.1/" or "http://49.112.50.65/" if you have a nonstandard model of Comcast modem.

Press "Enter." Enter a username and password if prompted. Contact your local Comcast ISP for the username and password for your modem, or try the following combinations: "username: root," "password: root;" "username: admin," "password: Motorola;" "username: admin," "password: w2402;" "username: cusadmin," "password: highspeed" or "username:", "password: icu4at!"
