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.

Note: 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.

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.
