based management interface. From your Web browser (Microsoft Internet Explorer or

Netscape Navigator, versions 5.0 or later), you will log in to the interface to define system

parameters, change password settings, view status windows to monitor network conditions,

and control the Gateway and its ports.

To access the SMCD3GN Wireless Cable Modem Gateway’s web-based management

screens, use the following procedure.

1. Launch a Web browser.

Option

Description

Enable UPnP

Configures your Gateway as a Universal Plug and Play (uPnP) Internet gateway. UPnP allows for dynamic

connectivity between devices on a network. A UPnP-enabled device like your Gateway can obtain an IP address,

advertise its capabilities, learn about other connected UPnP devices and then communicate directly with those

devices. The same device can end its connection cleanly when it wishes to leave the UPnP community. The intent

of UPnP is to support zero-configuration, "invisible" networking of devices including intelligent appliances, PCs,

printers, and other smart devices using standard protocols.

Check = uPnP is enabled on the Gateway. (

default)

Uncheck = uPnP is disabled on the Gateway.

Enable HNAP

Configures your Gateway as a Home Network Administration Protocol (HNAP) device. HNAP allows your

Gateway to be configured and managed by remote entities, such as Network Magic or any software application

that discovers and manages network devices.

Check = HNAP is enabled on the Gateway.

Uncheck = HNAP is disabled on the Gateway. (

default)
