Chapter 1: Introduction
This chapter describes the package contents and provides a list of features and application
illustrations of the 11g Wireless Broadband Router.
1-1 About The 11g Wireless Broadband Router
The 11g Wireless Broadband Router is a hybrid design product which combines Ethernet
technology and wireless access into a single stand-alone unit. The device allows you take
advantages of both mobility and fast connection. All PCs whenever on wireless LAN or
Ethernet LAN can share files, printers and other network resource. Moreover, all users can
share single account of Internet access by having this device connect to a DSL/Cable modem.
Ethernet / Fast Ethernet
Ethernet is the most widely-used network access method, especially in a Local Area Network
(LAN) and is defined by the IEEE as the 802.3 standard. Normally, Ethernet is a shared media
LAN. All stations on the segment share the total bandwidth, which could be 10Mbps (Ethernet),
100Mbps (Fast Ethernet), With a switched Ethernet, each sender and receiver has the full
bandwidth.
Fast Ethernet is defined as IEEE 802.3u standard, a high-speed version of Ethernet with
100Mbps transmission rate.
Wireless LAN
Wireless Local Area Network systems (WLANs) transmit and receive data through the air by
using radio frequency (RF). This offers some advantages like mobility, ease of installation, and
scalability over traditional wired systems.
Mobility: WLANs combine data connectivity with user mobility. This provides users with
access to network anywhere in their organization. For example, users can roam from a
conference room to their office without being disconnected from the LAN. This is impossible
with wired networks.
Ease of Installation: Eliminating the need to deploy network cable on walls and ceilings,
Installing WLANs is easy for novice and expert users alike.
Scalability: WLAN topologies are easy to change in various ways from peer-to-peer networks
for a small group of users to full infrastructure networks for hundreds of users roaming over a
broad area.
Wireless LAN is suitable for difficult-to-wire and frequently changing environments. It’s also
an ideal solution for mobile workers to access network resource and for setting a temporary
LAN when necessary
Wireless LANs can be set as “Ad-hoc” network and “Infrastructure” network. Unlike the
“Ad-hoc network”, where users on the LAN send data directly to each other, the
“Infrastructure” network includes an access point and users on the “Infrastructure” network
send data to that dedicated access point. 11g Wireless Broadband Router uses “Infrastructure”
network as Wireless LANs. Each wireless LAN PC within the range of the access point can
communicate with other wireless LAN PCs within the range.

4-3 Virtual Server Settings
The Virtual Server Settings application allows you to set up a maximum of ten public services
that can be accessed by external users of the Internet, such as a Web Address, Email, FTP etc..
Each service is provided by a dedicated network computer (server) configured with a fixed IP
Address. Although the internal service addresses are not directly accessible to the external user,
the Wireless Broadband router is able to identify the service requested by the service port
number and redirects the request to the appropriate internal IP Address/server. To use this
application, it is recommended you use a fixed Public IP Address from your ISP. Note that your
Wireless Broadband router supports only one server of any particular type.
This router also support UPnP Forwarding. You can use either Virtual Server Settings or UPnP
Forwarding by clicking the button to change setting page. Please note that do not set the same
function server to different IP Address in different setting pages.

UPnP Forwarding
UPnP (Universal Plug and Play) is a standard introduced from Microsoft and
UPnP Forum for interoperability. Currently, this function supported by this
device allows you to set virtual server from Windows OS that supports UPnP,
such as Windows XP.
UPnP Function: Check “Enable” will allow LAN side PCs that support
UPnP to set virtual server.
Before you enable the UPnP Forwarding, you have to
set up individual network computers to act as servers
and configure each with a fixed IP Address.
In the “One Page Setup” screen, ensure the “Private
43
IP Address” is set to the Router’s default setting of
192.168.1.1. If a fixed Public IP Address is to be used,
select “Specify an IP address” and enter the IP
Address and other necessary information provided by
your ISP.
UPnP Control: Check “Enable” will allow LAN side PCs that support
UPnP to directly configure the settings provided in this

Application Name UPnP has ten pre-setting forwarding rules, which are
well-known applications. You can enter any name to
present the additional settings beside those pre-setting
rules.
Ext. Port Most of applications usually use their individual port
number for its incoming and outgoing data packets.
However, some of the application may use different
port number for incoming and outgoing data packets.
In this case, you have to enter the port number used by
incoming data packets here.
Protocol Specify the protocol type as “TCP” or “UDP” which
is used by specific service.
Int. Ports Most of applications usually use their individual port
number for its incoming and outgoing data packets.
However, some of the application may use different
port number for incoming and outgoing data packets.
In this case, you have to enter the port number used by
outgoing data packets here.
IP Address Enter the appropriate IP Addresses of the service
computers in the “IP Address” locations.
Enable Check to make this forwarding setting active.
Apply Click this button after making any changes for
activating the settings.
Cancel Click this button if you are not satisfied with the
settings in this page before clicking Apply.
Example: If the service port number 80~80 (representing an HTTP web address)
44
is entered in “Ports” and 192.168.1.100 is entered in “IP Address”, then all
HTTP requests from external Internet users will be directed to the PC/server
with the 192.168.1.100 fixed IP Address.
4-4 DMZ Host
The DMZ Host application allows unrestricted 2-way communication between a single LAN
PC and other Internet users or servers. This application is useful for supporting special-purpose
services such as video-conferencing and gaming, that require proprietary client software and/or
2-way user communication.
To use this application, you must first obtain a fixed Public IP Address from your ISP. Note that
in order to provide unrestricted access, the Firewall provided by the Wireless Broadband router
to protect this port is disabled, thus creating a potentially serious security risk.
It is recommended that this application is disabled when it is not in use by entering “0” in the
“DMZ Host”field.
The Multi DMZ allows you to map the public IP addresses to your LAN PCs, should you get
more than one public IP address from your ISP. This function is useful to set up your servers,
such as an FTP server, web server, and so on, with public IP addresses, but still keep them
within your LAN group.
With the public IP addresses, Internet users will access your servers more easily and those
servers can still communicate with other PCs in you LAN by using Network Neighborhood.
Before setting up a LAN PC to act as a DMZ Host, you should configure it
45
using a fixed IP Address.
Note: In the “One Page Setup” screen, ensure the Private IP Address is set to
the Wireless Broadband router’s default setting of 192.168.1.1. In the Public IP
Address area, select “Specify an IP Address”, and then enter the IP Address
and other necessary information provided by your ISP.

4-9 DDNS
“DDNS” is an acronym for Dynamic Domain Name Service. Whenever you set up the web
servers, mail servers, or sometimes ftp servers, you need “Domain Name” to help Internet
users reach your servers easily.
Internet actually runs on IP Addresses which are numerical order, for example “66.37.215.53”.
These IP Address identify the location of each device connected to Internet. However, the
human brain does not easily remember this numbering system, so a system that allocate domain
name such as “www.dyndns.org” provides an easier method. If you type “66.37.215.53” or
“www.dyndns.org” in the web browser’s address bar, the browser will show the same web page.
This is because both methods relate to the same web server. The “Domain Name Servers”
used to manage the Internet will translate “www.dyndns.org” into the IP Address
“66.37.215.53” in order to allow your browser to find the web server and display the correct
web page in your browser.
53
If your “WAN Connection Type”, as shown in One Page Setup section, is “Obtain IP Address
Automatically”, “PPPoE”, or “PPTP” with dynamic IP address assigned by ISP, it will cause an
error when you set up the public computer servers in your LAN side PCs. Internet users may
not be able to reach your servers because your WAN side IP address may change each time you
initiate the connection to your ISP. The DDNS function will help to map your IP address to your
domain name when your ISP assigns a new dynamic IP Address.
Note that this DDNS function acts as the client appliance of DDNS service and is only able to
be use in conjunction with the service provided by DynDNS.org. Before you begin using this
function, you will need to apply to DynDNS.org (or 3322.org)to be able to use the service.
Please visit www.dyndns.org (or www.3322.org) for further information.

experiencing a problem. Please contact your dealer.
Q: Why can’t I configure the 11g Wireless Broadband router ?
First, check whether the 11g Wireless Broadband router is properly installed or not, including
the LAN and WAN connections, and that all devices are switched on.
Next, check the IP configuration of your PC:
For Windows 95/98 users: run winipcfg.exe or winipcfg from Run on
the Start menu. If there are no IP addresses shown, click Release All
and then click Renew All to get the IP addresses.
For Windows NT 4.0 users: run ipconfig.exe or ipconfig from Run on
the Start menu and follow the instruction as above.
Ensure that your PC and the 11g Wireless Broadband router are on the same
network segment. If you are not sure, initiate the DHCP function and set you
PC to obtain an IP address automatically.
Ensure that your PC is using an IP Address within the range 192.168.1.2 to
192.168.1.254 and thus compatible with the 11g Wireless Broadband router
68
default IP address of 192.168.1.1
Finally, use the Ping command in MS-DOS mode to verify the network
connection:
Ping 127.0.0.1 to check the TCP/IP stack of your computer
Ping gateway IP (Default: 192.168.1.1) to check the internal link of
network.
Note if you’re not able to view the web configuration screen for the 11g Wireless Broadband
router , make sure that you remove any proxy setting within your Internet browser, or remove

192.168.1.2~192.168.1.254.
Q: Where should the 11g Wireless Broadband router be installed on the network?
In a typical environment, the 11g Wireless Broadband router should be installed between the
ADSL/Cable modem and your LAN. Connect the 11g Wireless Broadband router to the
Ethernet port of the ADSL/Cable modem, and connect your PCs to the RJ45 jack on the LAN
side.
Q: Does the 11g Wireless Broadband router support IPX or AppleTalk?
No. The 11g Wireless Broadband router was designed to provide a multiple user LAN with
shared Internet access and supports only the TCP/IP Protocol. If your Novell or Apple system is
configured with TCP/IP, the 11g Wireless Broadband router can support them.
Q: Does the 11g Wireless Broadband router support 100Mb Ethernet?
Yes, the 11g Wireless Broadband router supports both 10Mb & 100Mb Ethernet on the LAN
side.
Q: What is “NAT” and what is it used for?
The Network Address Translation (NAT) Protocol translates multiple IP Addresses on a private
LAN into a single public IP Address that is accessible to the Internet. NAT not only provides the
basis for multiple IP Address sharing but also adds to the LAN’s security since the multiple IP
Addresses of LAN computers are never transmitted directly to the Internet.
Q: How can 11g Wireless Broadband router share single user account to multiple users?
11g Wireless Broadband router combines the following technologies to enable this function.
NAT (Network Address Translation): NAT is a technology which can create a private network
domain behind a public IP. It is usually used as a firewall. It can also be used when there are not
enough IP Address.
DHCP (Dynamic Host Configuration Protocol): DHCP is a protocol used to assign IP Address
to internal computers automatically. It can save a lot of IP configuration. This protocol is
supported by Windows 95/NT, Mac OS, and many other popular OS.
DNS (Domain name service): DNS is a protocol which translates a Domain Name to IP
Addresses that Internet host can handle. Addressing systems using Domain name, like
www.yahoo.com, is easier to use than an IP address, such as 204.71.177.70.
Q: What operating systems does 11g Wireless Broadband router series support?
11g Wireless Broadband router uses standard TCP/IP protocol, it can be operated as long as
you have the TCP/IP protocol installed in your operating system (For example: Windows 9x,
Windows NT, Windows 2000, etc.)
Q: Can I use multiple E-mail accounts if I use 11g Wireless Broadband router ?
70
Yes, you can. Some people think having one Internet account mean that they can only have one
E-mail account. However, E-mail is set by mailbox accounts and is different to the account you
use to connect to your ISP. If you want more E-mail accounts, you should contact your ISP or
you can browse the Internet to apply for a free E-mail account.
Q: Can Internet users access LAN computers?
11g Wireless Broadband router uses NAT to route all in/out packets. All external users can
only see the IP of the 11g Wireless Broadband router but cannot access LAN computers. The
LAN computers are well protected with the 11g Wireless Broadband router ’s natural firewall.
Q: When should I use DMZ host?
Enable DMZ host when you want to have unrestricted communication between your PC and the
Internet, for example, playing Internet games (i.e. Ages of Empire) or having multimedia
conferences (i.e. NetMeeting).
Q: Does the 11g Wireless Broadband router support PPTP of VPN packets pass
through?
Yes. 11g Wireless Broadband router supports single session PPTP pass through.
Q: Does the 11g Wireless Broadband router series support IPsec?
Yes. 11g Wireless Broadband router supports single session IPsec pass through.

The adaptation of the Ethernet standard for Local Area Networks (LANs). 10Base-T uses a
twisted pair cable with maximum lengths of 100 meters and transmits data at 10Mbps
maximum. 100Base-T is similar, but uses two different twisted pair configurations and
transmits at 100Mbps maximum.
Ad-hoc Network
Also known as the peer-to-peer network, an ad-hoc network allows all PCs participating in a
wireless network and being within range, to communicate with each other. User’s in the same
ad-hoc network can share files, printers, and other network resources.
Adapter
A device that makes the connection to a network segment, such as Ethernet and modem cards
and adapters.
ADSL
Asymmetric Digital Subscriber Line (ADSL), as it’s name indicates, is an asymmetrical data
trasmission technology with higher traffic rate downstream and lower traffic rate upstream.
ADSL technology satisfies the bandwidth requirements of applications which demand
“asymmetric” traffic, such as web surfing, file downloads and telecommuting.
Bandwidth
The amount of data that can be transmitted in a fixed amount of time.
Browser
A software application used to locate and display Web pages. Examples include Netscape
Navigator and Microsoft Internet Explorer.
BSS
BSS is the acronym of Basic Service Set that consists of a wireless access point and a group of
wireless client PCs.
Communication Protocols
Communication between devices requires they agree on the format in which the data is to be
transmitted, sent and received. The communication protocols are a set of rules that define the
data format.
Cookie
A Cookie is a piece of data stored on your PC that a web server can retrieve later to identify
your machine. It is normally a text with ID number, but can include other information.
DHCP
DHCP, short for Dynamic Host Configuration Protocol, is a protocol for assigning dynamic IP
Addresses to devices on a network. Dynamic Addressing means that a device can have a
different IP Address each time it connects to the network.
Domain Name
A name that identifies one or more IP Addresses. For example, the domain name microsoft.com
74
represents about a dozen IP Addresses. Domain names are used in URLs to identify particular
Web pages. For example, in the URL http://www.pcwebopedia.com/index.html, the domain
name is pcwebopedia.com.
DoS
DoS is the abbreviation for Denial of Service. This occurs when a computer or network is
overwhelmed to the point that it can no longer function normally. For example, a hacker may
use fake IP addresses to accumulate numerous connections to flood the server he wants to
attack.
DDNS
DDNS is an acronym for Dynamic Domain Name Service. It helps map the domain name of a
host which has a dynamic public IP address to the IP address that is allocated each time the ISP
assigns a new IP address.
DNS
Short for Domain Name Server, DNS translates domain names into IP Addresses and help us
recognize and remember domain names as they are alphabetic in form. The Internet actually
runs on numbered IP Addresses. DNS servers translate domain names into their respective IP
Addresses.
DSSS
Also known as Direct Sequence Spread Spectrum, it is a radio transmission method that
continuously changes frequencies.
Ethernet

opinions.
Intranet
A network based on the TCP/IP Protocol (an internet) belonging to an organization, and
accessible only by that organization's members, employees, or others with authorization.
Infrastructure Network
Unlike “Ad-hoc” network, where users on a wireless LAN send data to each other directly,
users’ on an “Infrastructure” network send data to the other point through a dedicated access
point. Additionally, the access point enables users on a wireless LAN to access an existing
wired network to take advantage of sharing the wired networks resources, such as files, printers,
and Internet access.
IP Address
An identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP
75
Protocol route messages based on the IP Address of the destination. The format of an IP address
is a 32-bit numeric address written as four numbers separated by periods. Each number can be
from zero to 255.
IPSec
Internet Protocol Security is a security standard for network transmission. It provides
authentication and packet encryption over the Internet.
ISP
Short for Internet Service Provider, a company that provides access to the Internet, usually for a
monthly fee. The ISP provides a software package, username, password and access phone
number allowing users to log on to the Internet, browse the World Wide Web and send and
receive e-mail.
Local Area Network (LAN)
A computer network that spans a relatively small area. Most LANs are confined to a single
building or group of buildings. However, one LAN can be connected to other LANs over any
distance via telephone lines and radio waves. A system of LANs connected in this way is called
a wide area network (WAN)
MAC Address
Short for Media Access Control Address and in a hardware address that uniquely identifies each
node of a network.
NAT
Short for Network Address Translation, a routing protocol that allows global IP Addresses to be
translated into multiple private IP Addresses for use on internal LAN networks. The explosion
in the use of the Internet has created a critical problem for the Internet Assigned Numbers
Authority (IANA) which is in charge of assigning IP Addresses to Internet users, ISPs etc.. NAT
is a technology that has been introduced to help maximize the utilization of assigned IAN and
global IP Addresses.
Network Protocol
Network protocols encapsulate and forward data packets from one interface to another.
PAP/CHAP ISP
Short for Password Authentication Protocol and Challenge Handshake Authentication Protocol.
Most ISPs use either one for user identification. If your ISP doesn’t support these two protocols,
contact your ISP for an authentication script.
PPP
Short for Point-to-Point Protocol, a communications protocol for transmitting information over
standard telephone lines between devices from different manufacturers.
PPPoE
Short for PPP over Ethernet, relying on two widely accepted standards, Ethernet and the
Point-to-Point Protocol. It’s a communications protocol for transmitting information between
devices from different manufacturers over an Ethernet.
PPTP
Short for Point to Point Tunneling Protocol, PPTP encapsulates the packet for transmission over
the Internet. It is similar to creating a private “tunnel” over a large public network and has
almost equal security to a private network without actually leasing a private line.
Protocol
An agreed format for transmitting, sending and receiving data between two devices.
76
Roaming
The ability for a wireless device moving from one access point’s range to another without
losing the connection.
Router
An Internet device that routes requests for information to other routers until the information’s
location is found and the data can be transmitted back to the origin of the request.
SPI
SPI is an acronym for Stateful Packet Inspection. The SPI engine examines not just the headers
of the packet, but also the packet contents, it can then determine more about the packet than just
its source and destination information. Moreover, stateful inspection firewalls also close off
ports until a connection to the specific port is requested.
TCP/IP
Short for Transmission Control Protocol and Internet Protocol, the suite of communications
protocols that enable hosts on the Internet to connect and exchange streams of data.
VPN
VPN is an acronym for Virtual Private Network. Via access control and encryption, VPN brings
the same security to data transmission through the Internet as if it being transmitted through a
private network. It not only takes advantage of economies of scale but also ensures high level
security while the packet is sent over the large public network.
Wide Area Network (WAN)
A system of LANs being connected by telephone lines and radio waves. Although some WANs
may be privately owned, they are usually considered a means of public access.
WEP
An acronym for Wired Equivalent Privacy. It is an encryption mechanism used to protect
your wireless data communications. WEP uses a combination of 64-bit/128-bit keys to encrypt
data that is transmitted between all points in a wireless network to insure data security. It is
described in the IEEE 802.11 standard.
