Change Password

For security, the gateway has its own user names and passwords. NETGEAR recommends

that you change the default passwords to more secure passwords. The ideal passwords

should contain no dictionary words from any language, and should be a mixture of both upper

and lower case letters, numbers, and symbols. Your passwords can be up to 30 characters.

saved settings file includes the new password.
