Chapter 1: Introduction
Congratulations on the purchase of your new Unicom 802.11g Wireless Router. Unicom’s
Wireless Router is a multi-function de ice pro iding the following ser ices:
• Shared Broadband Internet Access for all LAN users.
• 4-Port Switching Hub for 10Base-T or 100Base-T connections.
• Wireless Access Point for 802.11b and 802.11g Wireless Stations.
Wireless Router Features
Unicom's 802.11g Wireless Router incorporates many ad anced features, carefully designed to
pro ide sophisticated functions while being easy to use.
Internet Access Features
• Shared Internet Access. All users on the LAN or WLAN can access the Internet
through the Wireless Router, using only a single external IP Address. The local (in alid)
IP Addresses are hidden from external sources. This process is called NAT (Network
Address Translation).
• DSL & Cable odem Support. The Wireless Router has a 10/100Base-T Ethernet
port for connecting a DSL or Cable Modem. All popular DSL and Cable Modems are
supported. SingTel RAS and Big Pond (Australia) login support is also included.
• PPPoE, and PPTP. The Internet (WAN port) connection supports PPPoE (PPP o er
Ethernet), PPTP (Peer-to-Peer Tunneling Protocol), as well as "Direct Connection" type
ser ices. Unnumbered IP with PPPoE is also supported.
• Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Wireless
Router supports both Dynamic IP Address (IP Address is allocated on connection) and
Fixed IP Address.
Advanced Internet Functions
• Communication Applications. Support for Internet communication applications, such
as interacti e Games, Telephony, and Conferencing applications, which are often difficult
to use when behind a Firewall, is included.
• Special Internet Applications. Applications that use non-standard connections or port
numbers are normally blocked by the Firewall. Application support is pro ided allowing
such applications to be used normally.

• Virtual Servers. This feature allows Internet users to access Internet ser ers on your
LAN. The required setup is quick and easy.
• DDNS Support. DDNS (Dynamic DNS) allows Internet users to connect to Virtual
Ser ers on your LAN using a domain name, e en if your IP address is not fixed.
• D Z. For each WAN (Internet) IP address allocated to you, only one (1) PC on your
local LAN can be configured to allow unrestricted 2-way communication with Ser ers or
indi idual users on the Internet. This pro ides the ability to run programs that are
incompatible with Firewalls.
• URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
• Internet Access Log. See which Internet connections ha e been made.
• Access Control. Using the Access Control feature, you can assign LAN users to
different groups, and determine which Internet ser ices are a ailable to each group.
• VPN Pass through Support. PCs with VPN (Virtual Pri ate Networking) software
using PPTP, L2TP and IPSec are transparently supported - no configuration is required.
Wireless Features
• Standards Compliant. The Wireless Router complies with the IEEE802.11g (DSSS)
specifications for Wireless LANs.
• Supports both 802.11b and 802.11g Wireless Stations. The 802.11g standard
pro ides for backward compatibility with the 802.11b standard, so that both 802.11b and
802.11g Wireless stations can be used simultaneously.
• Speeds to 54 bps. All speeds up to the 802.11g maximum of 54Mbps are supported.
• WEP support. Support for WEP (Wired Equi alent Pri acy) is included. Key sizes of
64 Bit and 128 Bit are supported.
• Wireless AC Access Control. The Wireless Access Control feature can check the
MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless
Stations can access your LAN.
• Simple Configuration. If the default settings can be changed quickly and easily.
LAN Features
• 4-Port Switching Hub. The Wireless Router incorporates a 4 Port 10/100Base-T
switching hub, making it easy to create or extend your LAN.
• DHCP Server Support. Dynamic Host Configuration Protocol pro ides a dynamic IP
address to PCs and other de ices upon request. The Wireless Router can act as a DHCP
Server for de ices on your local LAN and WLAN.
Configuration & Management
• Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for
configuration.
• Configuration File Upload/Download. Sa e (download) the configuration data from
the Wireless Router to your PC, and restore (upload) a pre iously sa ed configuration file
to the Wireless Router.
• Remote anagement. The Wireless Router can be managed from any PC on your
LAN. If an Internet connection exists, the router can also be configured ia the Internet.
• Network Diagnostics. The Wireless Router can perform a Ping or DNS lookup.
• UPnP Support. UPnP (Uni ersal Plug and Play) allows automatic disco ery and
configuration of the Wireless Router. UPnP is by supported by Windows ME, XP, or
later.

Security Features
• Password-protected Configuration. Optional password protection is pro ided to
pre ent unauthorized users from modifying the configuration data and settings.
• Wireless LAN Security. WEP (Wired Equi alent Pri acy) is supported, as well as
Wireless access control to pre ent unknown wireless stations from accessing your LAN.
• NAT Protection. An intrinsic side effect of NAT (Network Address Translation)
technology is that by allowing all LAN users to share a single IP address, the location and
e en the existence of each PC is hidden. From the external iewpoint, there is no network,
only a single de ice - the Wireless Router.
• Protection against DoS attacks. DoS (Denial of Ser ice) attacks can flood your
Internet connection with in alid packets and connection requests, using so much
bandwidth and so many resources that Internet access becomes una ailable. The Wireless
Router incorporates protection against DoS attacks.

About t e Operation Mode
AP Mode
When acting as an access point, this de ice connects all the remote stations (Desktop/notebook
PC with wireless network adapter) to a wired network. All stations can ha e Internet access
pro ided the Access Point has an Internet connection.
Bridge Mode
The WDS (Wireless Distributed System) function lets this access point act as a wireless LAN
access point and repeater at the same time. Users can use this feature to build up a large
wireless network in a large space like airports, hotels and schools …etc. This feature is also
useful when users want to bridge networks between buildings where it is impossible to deploy
network cable connections between these buildings.
Repeater
Refer to the illustration below. While acting as a Bridge, AP1 (Station 1) and AP2 (Station 2)
can communicate with each other through wireless interface (with WDS). Thus Station 1 can
communicate with Station 2 and both Station 1 and Station 2 are able to access the Internet
e en if only one of the stations has the Internet connection.
To set the operation mode to Bridge, please go to “Wireless 
Basi Settings”, in the
“Mode” field click the down arrow  to select AP mode. And go to “Wireless 
WDS
Settings” to enable WDS.
