INTRODUCTION
With the explosive growth of the Internet, accessing information and
services at any time, day or night has become a standard requirement for
most people. The era of the standalone PC is waning. Networking
technology is moving out of the exclusive domain of corporations and
into homes with at least two computers.
This integrated access device combines Internet gateway functions with
wireless LAN and Fast Ethernet switch. Designed for the business and
home, it saves you the cost of installing a separate modem and ISP line
for each computer, while providing ready connection for the users, with or
without the network wires.
Broadband network access is also gaining ground. However, allowing
more than two computers to access the Internet at the same time means
less affordable, higher costs. Thus, there is a need to share one legal IP
address over a single Internet connection to link the home with the
Internet.
The scarcity of IP addresses and using a shared Internet connection
through an Internet sharing device can solve high network access costs.
All linked computers can make full use of broadband capabilities over
such a device.
This device not only comes equipped with a wide range of features, but
also can be installed and configured right out of the box. This device
supports a simple local area network and Internet access share, offering
great cost savings.
The local area network connects up home computers while also allowing
any of the computers to access the Internet, share resources, or play online
games—the basis of the family computing lifestyle.
4
Applications:
Broadband Internet access:
Several computers can share one high-speed broadband connection
through wireless or wired (WLAN, LAN and WAN-Internet).
Resource sharing:
Share resources such as printers, scanners and other peripherals.
File sharing:
Exchange data, messages, and distribute files thus making good use of
hard disk space.
Online gaming:
Through the local area network, online gaming and e-commerce services
can be easily setup.
Firewall:
A built-in firewall function — for security and anti-hack system.
Features:
 High speed data transfer rate
 Supports NAT for share 1 IP address to all LAN user.
 Supports PPPoE and PPTP protocol for Dial-Up ADSL.
 Supports 64/128 bit WEP Encryption
 Supports DHCP Server / Client.
 Supports UPnP (Universal Plug and Play).
 Supports virtual server mapping.
 Supports packet filtering.
 Simple Firewall protection.
 Upgradeable firmware for future function.
 Simple setting using Quick Setup.
 Easy configuration via WEB Browser.

UNPACKING AND SETUP
This chapter provides unpacking and setup information for the Wireless
Broadband Router.
Unpacking
Open the box of the Wireless Broadband Router and carefully unpack it.
The box should contain the following items:
 One Wireless Internet Broadband Router
 One external power adapter
 One CD-Rom with this User’s Guide
If any item is found missing or damaged, please contact your local reseller
for replacement.
Setup
The setup of the Wireless Broadband Router can be performed properly
using the following methods:
 The power outlet should be within 1.82 meters (6 feet) of the
Broadband Router.
 Visually inspect the DC power jack and make sure that it is fully
secured to the power adapter.
 Make sure that there is proper heat dissipation from and adequate
ventilation around the Broadband Router. Do not place heavy
objects on the Broadband Router.
 Fix the direction of the antennas. Try to place the Wireless
Router in a position that can best cover your wireless network.
Normally, the higher you place the antenna, the better the
performance will be. The antenna’s position enhances the
receiving sensitivity.
