Protecting Access to Your Wireless 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 automatically disconnects. When
prompted, enter admin for the modem router user name and password for the modem router
password. You can use the following procedures to change the modem router’s password and the
period for the administrator’s login time-out.
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 case and lower case letters, numbers, and symbols. Your password can be up to 30
characters.
ote: The user name and password are not the same as any other user name or password
your might use to log in to your Internet connection.
