1 Introduction
1.1 Overview
Thank you for choosing this Wireless Broadband Router. The
Wireless Broadband Route features a wireless Access Point, a
4-port LAN switch and a WAN port, which extends your existing
broadband Cable/ADSL connection. It allows the broadband
connection to be shared through either the IEEE 802.11g Access
Point feature or the 10/100Base-TX Ethernet switch, which also
eliminates the purchase of additional hub or switch. Now your
wired and wireless network are integrated to enjoy various
bandwidth-consuming applications over the Internet.
With the support of new emerged 802.11g standard, the Access
Point provides data transfer of up to 54 Mbps, up to 5 times faster
than 802.11b. Since 802.11g operates on the same frequency of
2.4 GHz as 802.11b, it is backwards compatible with existing Wi-Fi
devices. The benefit is that you can preserve the existing 802.11b
infrastructure while migrating to the new screaming fast 802.11g.
The integrated DHCP server automatically assigns IP addresses to
your LAN devices, and with the built-in Network Address
Translation (NAT) function, your LAN is protected against outside
intruders. The router can also be configured to filter internal access
to the Internet. It is designed to provide a reliable Internet access
solution for the corporate environment, the small office and the
home user.
1.2 Features
• One 10/100 Base-TX RJ-45 auto sensing and crossover
Ethernet WAN port for Broadband connection (Cable/DSL
or direct Ethernet)
• Four RJ-45 LAN ports for 10/100Base-TX auto sensing &
crossover Ethernet Switch LAN connection

reach it easily.
• Avoid placing the device in places where people may walk
on the cables. Also keep it away from direct sunshine or
heat sources.
• Place the device on a flat and stable stand.
Connecting the Wireless Broadband Router
Prior to connecting the hardware, make sure to power off your
Ethernet device, Cable/ADSL modem and Wireless Broadband
Router. Then follow the steps below to connect the related devices.
Step 1 Connecting Your PC to the LAN port.
Attach one end of the Ethernet cable with RJ-45
connectors to your hub, switch or a PC’s Ethernet port,
and the other end to one of the LAN ports of your
Wireless Broadband Router.
Step 2 Connecting Cable/ADSL Modem to the Internet/WAN
port.
Connect the Ethernet cable attaching to your Cable/ADSL
modem to the Internet/WAN port of your Wireless
Broadband Router.

3 Setting Up Ethernet/WLAN Client
To access the Wireless Broadband Router via Ethernet or wireless
network, you must properly configure the network settings of your
Ethernet or wireless client PC. As the Wireless Broadband Router
is configured with the default IP address of 192.168.1.1 and
subnet mask of 255.255.255.0, and its DHCP server is enabled
by default, you can configure your PC’s TCP/IP settings as one of
the following:
1. To use dynamic IP: Set your PC to be DHCP client to accept
the dynamic IP from the router.
2. To use static IP: Set the IP address as 192.168.1.x (x is
between 2 and 254), subnet mask as 255.255.255.0 and the
gateway as 192.168.1.1 to be on the same subnet with the
router.
This chapter describes how to configure your PC to be a DHCP
client for initial connection to the device. If you have modified the
router’s network setting, your LAN/WLAN clients should make
appropriate changes in order to make successful connection.
3.1 Setting up Ethernet Client
To access the Wireless Broadband Router via Ethernet, make sure
your PC is equipped with Ethernet network card and has
appropriate network card driver and TCP/IP installed.
Note:
1. If TCP/IP protocol is not installed on your PC, refer to Windows
documentations for installation instructions.
2. For initial verification, we suggest that you connect only one PC
directly to an Ethernet port on the Wireless Broadband Router, not
through a hub.
