To change the administrator login:
Open an Internet browser. In the address field, type in: 192.168.100.1
Enter.
The default username is: admin
The default password is: motorola
(all lower case)
Click Login.
Click the "Advanced" tab on the top right side.
Click the "Security" tab.
Under Security, where it shows "Username & Password" you can change both the username and password if you like.
Username: admin
Current Password: motorola
New username: You may change the username or keep it at 'admin' by typing in: admin
New Password: The new password may be up to 15 characters: a to z and 0-9, upper and lowercase accepted. No special characters
Now click SAVE.
Please note:
Both the Username and Password are case sensitive. If you change either of these and forget what they are you will not be able to access the modem without doing a factory reset.
(this will return the Username and Password to the factory defaults. There is no other way to recover the password and username).
