Protecting Your Network
This chapter describes how to use the basic firewall features of the DG834 ADSL Modem Router
to protect your network. It also describes how to configure Trend Micro Home Network Security.
Protecting Access to Your DG834 ADSL Modem Router
For security reasons, the modem router has its own user name and password. Also, after a period
of inactivity for a set length of time, the administrator login will automatically disconnect. When
prompted, enter admin for the modem router User Name and password for the modem router
Password. You can use procedures below to change the modem router's password and the amount
of time for the administrator’s login timeout.
NETGEAR recommends that you change this password to a more secure password. The ideal
password should contain no dictionary words from any language, and should be a mixture of both
upper and lower case letters, numbers, and symbols. Your password can be up to 30 characters.
How to Change the Built-In Password
1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
User Name of admin, default password of password, or using whatever Password and LAN
address you have chosen for the modem router.
Note: The user name and password are not the same as any user name or password your
may use to log in to your Internet connection.
