Chapter 1 Introduction
Congratulations on your purchase of an Instant Wireless Broadband Router with 4-port Fast Ethernet Switch and
802.11b/g for cable and DSL application. The Wireless Broadband Router is the perfect option to connect a small
group of PCs to a high-speed Broadband Internet connection or to an Ethernet backbone. Configurable as a
DHCP server, the Broadband Router acts as the only externally recognized Internet device on your local area
network (LAN). The Router serves as an Internet firewall, protecting your network from being accessed by outside
users.
1.1 Overview
Unlike a simple hub or switch, the setup of the Cable/DSL Router consists of more than simply plugging
everything together. Because the Router acts as a DHCP server, you will have to set some values within the
Router, and also configure your networked PCs to accept the IP Addresses the Router chooses to assign them.
And generally there are three different operating modes for your applications. And you can know which mode is
necessary for your system from ISP. These three modes are PPPoE, DHCP client and Static IP. Actually all these
are for IP address of WAN.

Chapter 3 Configuration
3.1 Determine your connection settings
Before you configure the router; you need to know the connection information supplied by your service provider.
3.2 Connecting the Wireless Broadband Router to your network
Unlike a simple hub or switch, the setup of the ADSL Router consists of more than simply plugging everything
together.
Because the Router acts as a DHCP server, you will have to set some values within the Router, and also
configure your networked PCs to accept the IP Addresses the Router chooses to assign them. Generally there
are several different operating modes for your applications. And you can know which mode is necessary for your
system from ISP. These modes are router, bridge, PPPoE+NAT and NAT.
3.3 Configuring with Web Browser
It is advisable to change the administrator password to safeguard the security of your network.
To configure the router, open your browser, type 'http://192.168.6.1' into the address bar and click 'Go' to get to
the login page. Save this address in your Favorites for future reference.
10
At the Password prompt, the User name is 'admin' and the password is ’admin’. You can change these later if
you wish. Click 'OK' to login.
11
You can use "Quick Setup" to setup the router, and choose the connect mode you prefer.
12
3.3.1 DHCP Server

automatically opened for applications like Netmeeting, online games, etc. You can choose to enable or disable
the UPnP Service.
15
3.4.1 Dynamic IP
If you set the WAN as a Dynamic IP, the router will get the WAN IP address automatically.
16
3.4.2 Static IP
You can set the router’s WAN IP as static IP address. You need to fill out the Subnet Mask, Default Gateway and
DSN too.
17
3.4.3 PPPoE Configuration
PPPoE is usually used by ISPs which provide ADSL line to their subscribers. Usually an ISP gives Login ID and
Password to users for login when connecting to Internet. Service Name, AC Name is usually optional.
MTU: Sometimes ISP sets different MTU size than 1492. This value would be set to hardware. Dial-on-demand:
If checked, router won’t dial this session until received a LANWAN packet. If unchecked, router dials this session
immediately after system powered up. Silent timeout: If specified a non-zero value, router disconnects this
session after specified idle time. Auto Reconnect: If checked, router redials this session if session previously
terminated by ISP. Dial Status: Current status of this session. May be “Connected”, “Connecting”, or “Disconnect”
Pressing the Save and Restart saves parameters and reboots the router.
18
3.4.4 Unnumbered PPPoE Configuration
Unnumbered PPPoE WAN type is a required feature in Japan. ISP assigns Login ID and Password to users for
login when connecting to Internet. Service Name, AC Name is usually optional. It’s required to set the following
parameters for Unnumbered PPPoE WAN type: IP address: The unnumbered IP subnet address, assigned by
ISP. Network Mask : Network size of the unnumbered IP subnet. NAPT for LAN hosts: If checked, the router
enables hardware NAPT function for LAN PCs using configured LAN IP address(ex:192.168.1.X). If unchecked,
NAPT is disabled and only routes packets to and from LAN PCs using unnumbered IP addresses. All other
options are same as those of PPPoE Setting in Section 3.4.1. Pressing the Save and Restart saves parameters
and reboots the router.
19
3.4.5 PPTP Setting

the network or another piece of hardware, such as the Router. A dynamic IP address may change every time your
computer connects to the network.
Encapsulation
The technique used by layered protocols in which a layer adds header information to the protocol data unit (PDU)
from the layer above. As an example, in Internet terminology, a packet would contain a header from the physical
layer, followed by a header from the network layer (IP), followed by a header from the transport layer (TCP),
followed by the application protocol data.

standard protocols and procedures for the Internet. RFCs can be found at www.ietf.org..
52
Route
The path that network traffic takes from its source to its destination. The route a datagram may follow can include
many routers and many physical networks. In the Internet, each datagram is routed separately.
Router
A system responsible for making decisions about which of several paths network (or Internet) traffic will follow. To
do this, it uses a routing protocol to gain information about the network and algorithms to choose the best route
based on several criteria known as "routing metrics".
Routing table
Information stored within a router that contains network path and status information. It is used to select the most
appropriate route to forward information along.
Routing Information Protocol
Routers periodically exchange information with one another so that they can determine minimum distance paths
between sources and destinations.
SNMP
Simple Network Management Protocol - The network management protocol of choice for TCP/IP-based Internet.

(2) IBM term for software interfaces that allow two UNIX application programs to talk via TCP/IP protocols.
Spanning-Tree Bridge Protocol (STP)
Spanning-Tree Bridge Protocol (STP) - Part of an IEEE standard. A mechanism for detecting and preventing
loops from occurring in a multi-bridged environment. When three or more LAN's segments are connected via
bridges, a loop can occur. Because a bridge forwards all packets that are not recognized as being local, some
packets can circulate for long periods of time, eventually degrading system performance. This algorithm ensures
only one path connects any pair of stations, selecting one bridge as the 'root' bridge, with the highest priority one
as identifier, from which all paths should radiate.
Spoofing
A method of fooling network end stations into believing that keep alive signals have come from and returned to
the host. Polls are received and returned locally at either end
53
Static IP Addresses
A static IP address is an IP address permanently assigned to computer in a TCP/IP network. Static IP addresses
are usually assigned to networked devices that are consistently accessed by multiple users, such as Server PCs,
or printers. If you are using your Router to share your cable or DSL Internet connection, contact your ISP to see if
they have assigned your home a static IP address. You will need that address during your Router's configuration.
Subnet
For routing purposes, IP networks can be divided into logical subnets by using a subnet mask. Values below
those of the mask are valid addresses on the subnet.
TCP
Transmission Control Protocol - The major transport protocol in the Internet suite of protocols provides reliable,
connection-oriented full-duplex streams.
TFTP
Trivial File Transfer Protocol - A simple file transfer protocol (a simplified version of FTP) that is often used to boot
diskless workstations and other network devices such as routers over a network (typically a LAN).
Telnet
The virtual terminal protocol in the Internet suite of protocols - Allows users of one host to log into a remote host
and act as normal terminal users of that host.
Transparent bridging
So named because the intelligence necessary to make relaying decisions exists in the bridge itself and is thus
transparent to the communicating workstations. It involves frame forwarding, learning workstation addresses and
ensuring no topology loops exist (in conjunction with the Spanning-Tree algorithm).
UDP
User Datagram Protocol - A connectionless transport protocol that runs on top of TCP/IP's IP. UDP, like TCP, uses
IP for delivery; however, unlike TCP, UDP provides for exchange of datagrams without acknowledgments or
guaranteed delivery. Best suited for small, independent requests, such as requesting a MIB value from an SNMP
agent, in which first setting up a connection would take more time than sending the data.
UNI signaling
User Network Interface signaling for ATM communications.
54
Virtual Connection (VC)
A link that seems and behaves like a dedicated point-to-point line or a system that delivers packets in sequence,
as happens on an actual point-to-point network. In reality, the data is delivered across a network via the most
appropriate route. The sending and receiving devices do not have to be aware of the options and the route is
chosen only when a message is sent. There is no pre-arrangement, so each virtual connection exists only for the
duration of that one transmission.
WAN
Wide area network - A data communications network that spans any distance and is usually provided by a public
carrier (such as a telephone company or service provider).

Appendix B Cabling / Connection
Network cables connect PCs in an Ethernet network Category 5, called "Cat5" for short is commonly used type of
network cable today.
Cat 5 cables are tipped with RJ-45 connectors, which fit into RJ-45 port.
