A modem/gateway device having a password retrieval function is provided that includes a user interface, a hardware processor, and a non-transitory memory configured to store one or more programs. The hardware processor executes the one or more programs to receive a request for a password retrieval in response to an input from the user interface, generate a message for retrieving a password for a wireless network, and transmit the message to a server. The password corresponds to an email address to which an email is to be sent by the server. The transmitted message instructs a password retrieval operation by the server to transmit the password to the email address.
