I entered the IP address: 192.168.1.1 and then I wish to manage my modem. However, I don't what is the log-in name and the password. Please teach me how to login it.
Try logging in with your DSL user name and password. If that doesn't work try admin and password. A last resort would be to hold in the reset button and set your modem up from scratch. Make sure you have the correct user name and password before you do this.
