Wireless-B Broadband Router
Chapter 1: Introduction
The Wireless Router lets you securely share your DSL or Cable Modem
Internet connection with all the computers in the house, both wireless and
wired. You can connect four computers directly to the Router by Ethernet
cables, and daisy-chain out to more hubs and switches to create as big a net-
work as you need.
Or, use the Router's built-in Wireless Access Point to connect your PC to the
network without stringing any wires. Just plug a wireless network adapter into
your notebook through a PC Card slot, and you're ready to go. Wireless net-
working doesn't get any easier.
Of course, you can connect more computers to the Router and your high-speed
Internet link -- just provide a wired or wireless network adapter for each one.
And once your computers are connected to the Router, they can communicate
with each other too, sharing resources like printers and all kinds of files --
music, digital pictures, and documents.
To protect your data and privacy, all wireless communications can be protect-
ed by 128-bit encryption, while the Router helps keep Internet intruders out of
your computers. It's all easier than you think -- the included Setup Wizards
walk you through configuring the Router, step by step.
With the Wireless-B Broadband Router, you're ready to start sharing printers,
files, and your Internet connection, the easy way.

Dynamic IP Addresses
A dynamic IP address is automatically assigned to a device on the network,
such as PCs and print servers. These IP addresses are called “dynamic”
because they are only temporarily assigned to the PC or device. After a certain
time period, they expire and may change. If a PC logs on to the network (or the
Internet) and its dynamic IP address has expired, the DHCP server will assign
it a new dynamic IP address.
For DSL users, many ISPs may require you to log on with a user name and
password to gain access to the Internet. This is called “Point to Point Protocol
over Ethernet” or PPPoE. PPPoE is similar to a dial-up connection but does not
have a phone number to dial into, and PPPoE is a dedicated high-speed con-
nection. PPPoE also will provide the Router with a dynamic IP address to
establish a connection to the Internet.
DHCP (Dynamic Host Configuration Protocol) Servers
DHCP frees you from having to assign IP addresses manually every time a new
user is added to your network. PCs and other network devices using dynamic
IP addressing are assigned a new IP address by a DHCP server. The PC or net-
work device obtaining an IP address is called the DHCP client. The Router’s
Internet port is, by default, set as a DHCP client.
DHCP servers can either be a designated PC on the network or another network
device, such as the Router. By default, a DHCP server is enabled on your
Router’s LAN ports. If you already have a DHCP server running on your net-
work, you must disable one of the two DHCP servers. If you run more than one
DHCP server on your network, you will experience network errors, such as
conflicting IP addresses. To disable the Router’s DHCP function, see the
DHCP section in Chapter 5: The Router’s Web-Based Utility.
NNoottee::Even if you assign a static IP address to a PC, other PCs can still use
DHCP’s dynamic IP addressing, as long as the static IP is not within the
DHCP range of the LAN IP Address.
If the Router’s DHCP function fails to provide a dynamic IP address for any
reason, please refer to Appendix A: Troubleshooting.
NNoottee::Since the Router is a device that connects two networks, it needs two
IP addresses—one for the LAN side, and one for the Internet side. In this
User Guide, you’ll see references to the “Internet IP address” and the “LAN
IP address.”
Since the Router has firewall security (NAT), only the Router’s Internet IP
address can be seen from the Internet.
However, even the Internet IP address can be blocked, so that the Router and
network seem invisible to the Internet—This is shown in the Filters section in
“Chapter 5: The Routers Web-Based Utility”.
Simply put, a router is a network device that connects two networks together.
In this instance, the Router connects your Local Area Network (LAN), or the
group of PCs in your home or office, to the Wide Area Network (WAN) that is
the Internet. The Router processes and regulates the data that travels between
these two networks.
Think of the Router as a network device with two sides. The first side is made
up of your private Local Area Network (LAN) of PCs. The other, public side
is the Internet, or the Wide Area Network (WAN), outside of your home or
office.
The Router’s firewall (NAT) protects your network of PCs so users on the pub-
lic, Internet side cannot “see” your PCs. This is how your LAN, or network,
remains private. The Router protects your network by inspecting the first pack-
et coming in from the Internet port before delivery to the final destination on
the LAN port. The Router inspects Internet port services like the web server,
ftp server, or other Internet applications, and, if allowed, it will forward the
packet to the appropriate PC on the LAN side.
What’s an IP Address?
IP stands for Internet Protocol. Every device on an IP-based network, includ-
ing PCs, print servers, and routers, requires an IP address to identify its “loca-
tion,” or address, on the network. This applies to both the Internet and LAN
connections.
There are two ways of assigning an IP address to your network devices.
Static IP Addresses
A static IP address is a fixed IP address that you assign manually to a PC or
other device on the network. Since a static IP address remains valid until you
disable it, static IP addressing insures that the device assigned it will have that
same IP address until you change it. Static IP addresses are commonly used
with network devices such as server PCs or print servers.
If you use the Router to share your cable or DSL Internet connection, contact
your ISP to find out if they have assigned a static IP address to your account.
If so, you will need that static IP address when configuring the Router. You can
get the information from your ISP.

Pressing the Reset Button and holding it in for a few seconds will clear all
of the Router’s data and restore the factory defaults. This should be done
only if you are experiencing heavy routing problems, and only after you
have exhausted all of the other troubleshooting options. By resetting the
Router, you run the risk of creating conflicts between your PCs’ actual IP
Addresses and what the Router thinks their IP Addresses should be. You
may be forced to reboot each network PC.
If the Router locks up, simply press the reset button or power it down for
three to five seconds by removing the power cable from the Router’s
Power Port. Leaving the power off for too long could result in the loss of
network connections.

Chapter 2: Planning Your Wireless
Network
A wireless LAN is exactly like a regular LAN, except that each computer in the
LAN uses a wireless adapter to connect to the network through a wireless con-
nection. Computers in a wireless LAN must be configured to share the same
radio channel.
The wireless adapter provides LAN access for wireless workstations. An inte-
grated wireless and wired LAN is called an Infrastructure configuration. A
group of wireless adapter users and this Router compose a Basic Service Set
(BSS). Each PC equipped with a wireless adapter in a BSS can talk to any
computer in a wired LAN infrastructure via this Router.
An infrastructure configuration extends the accessibility of a PC with a wire-
less adapter to a wired LAN, and doubles the effective wireless transmission
range for two PCs equipped with a wireless adapter
Infrastructure mode also supports roaming capabilities for mobile users. More
than one BSS can be configured as an Extended Service Set (ESS). This con-
tinuous network allows users to roam freely within an ESS. All PCs that are
equipped with a wireless adapter, and are within one ESS, must be configured
with the same ESS ID.
Before enabling an ESS with roaming capability, it is recommended to select a
feasible radio channel and optimum Router position. Proper positioning com-
bined with a clear radio signal will greatly enhance performance.

4. Connect the Power Adapter (included) to the Router’s Power port and plug
the other end into a power outlet.
• The Power LED will blink green as soon as the power adapter is con-
nected.
5. Power on the cable or DSL modem. Verify that the power is on by checking
the Internet LED in the Internet column on the front of the Router. The
Link LED will be illuminated if the power is on and the modem is ready.
6. Press the Reset button on the back of the Router. Hold the button in for three
seconds. This restores the Router’s default settings.
7. Power on your PC.
The Router is now connected.
Continue to the next chapter to configure your PCs.
For Wireless Connections: In addition to accessing the Router through an
Ethernet connection, a wireless connection can be used to access the Router.
After powering on the Router and connecting it to your modem, enter the
Router’s IP Address in the Address field of your wireless PC’s web-browser as
follows: http://192.168.1.1 and press Enter.
IImmppoorrttaanntt::
The Router is configured by default to work out of the box with
all Network Everywhere Wireless Adapters. If you have changed the
defaults on your Network Everywhere Wireless Adapters, or are using
other wireless adapters, you must temporarily change your wireless
adapter settings to: (SSID = wireless) in order to initially access the Router
wirelessly. After you have accessed the Router with the default settings,
you can change the Router’s settings to coincide with your Network set-
tings and reset your adapters.
IImmppoorrttaanntt::
Some ISPs—most notably some cable providers—configure
their networks so that you do not have to enter a full Internet address into
your web browser or e-mail application to reach your home page or
receive your e-mail. If your Internet home page address is something very
simple, such as “www”, rather than “www.networkeverywhere.com”, or
your e-mail server’s address is something similar to “e-mail” or “pop3”,
rather than “pop.mail.networkeverywhere.com”, you won’t be able to
properly configure the Router until you determine the actual Internet
addresses of your Web and e-mail connections.
You mmuussttobtain this information prior to connecting the Router to your net-
work. You can obtain this information by contacting your ISP.
Chapter 3: Connecting the Router
Before plugging everything together, it’s always a good idea to have everything
you’ll need to get the Router up and running. Depending upon how you con-
figure the Router in Chapter 5: The Router’s Web-based Utility, you may need
some of the following values from your ISP:
When connecting through a Static IP connection, be sure to have 1) Your
broadband-configured PC’s fixed Internet IP Address, 2) Your broadband-
configured PC’s Computer Name and Workgroup Name, 3) Your Subnet
Mask, 4) Your Default Gateway, and 5) Your Primary DNS IP address.
When connecting through a PPPoE connection, be sure to have 1) Your
PPPoE User Name and 2) Your PPPoE Password.
The installation technician from your ISP should have left this information with
you after installing your broadband connection. If not, you can call your ISP to
request the data.
Once you have the above values, you can begin the Router’s installation and
setup.
Once you are sure that you have the above values on hand, you can begin the
Installation and Setup of the Router.
1. Power everything down, including your PCs, your cable or DSL modem and
the Router.
2. Connect an Ethernet cable from one of your PC’s Ethernet ports to one of the
Router’s Ethernet ports. Do the same with all the PCs you wish to connect to
the Router.
In addition to accessing the Router through an Ethernet connection, a wire-
less connection can be used to access the Router. See the “For Wireless
Connections” note that follows these connection instructions.
3. Connect another Ethernet cable from your cable or DSL modem to the
Router’s Internet port.

Chapter 4: Configuring the PCs
These instructions will help you configure each of your computers to commu-
nicate with the Router.
To do this, you will need to configure your PC’s network settings to obtain an
IP (or TCP/IP) address automatically. Computers use IP addresses to commu-
nicate with each other across a network or the Internet.
You will need to know which operating system your computer is running, such
as Windows 98 SE, Millennium, 2000, or XP. You can find out by clicking the
Start button and then selecting the Settings option. (If your Start menu does-
n’t have a Settings option, you’re running Windows XP. You can select the
Control Panel directly from the Start Menu.) Then, click Control Panel and
double-click the System icon. Click the Cancel button when done.
Once you know which Windows operating system you are running, follow the
directions in this step for your computer’s operating system. If you PC is not
configured with the TCP/IP protocol, you will need to do this for each com-
puter you are connecting to the Router.
The next few pages tell you, step by step, how to configure your TCP/IP set-
tings based on the type of Windows operating system you are using. Once
you've configured your computers, continue to Chapter 5: The Router’s Web-
based Utility.
1. Click the Start button, click Settings and open the Control Panel. From
there, double-click the Network icon to open the Network screen.

Chapter 5: The Router’s
Web-based Utility
Use the Router’s web-based utility to administer it. This chapter will describe
each web page in the Utility and each page’s key functions. The utility can be
accessed via your web browser through use of a computer connected to the
Router.
For a basic network setup, most users only have to use the following screens of
the utility:
• Setup Enter the settings provided by your ISP.
• Password The Router’s default password is admin. To secure the Router,
change the Password from its default.
The WEP, Status, DHCP, Log, and Help tabs are also available for basic setup.
For advanced setup, click the Advanced Setup tab to access these screens:
Filters, Forwarding, Dynamic Routing, Static Routing, DMZ Host, MAC Addr
Clone, and Wireless.
To access the web-based utility of the Router, launch Internet Explorer or
Netscape Navigator, and enter the Router’s default IP address, 192.168.1.1, in
the Address field, as shown in Figure 5-1. Then, press Enter.
16
Upon entering the address into the web browser, a password request page will
pop up, as shown in Figure 5-2a. (Windows XP users will see a “Connect to
192.168.1.1” window, shown in Figure 5-2b.)
Leave the User Name field empty, and enter admin (the default password) in
lowercase letters in the Password field. Then, click the OK button.
To apply any of the settings you change on a page of the Utility, click the Apply
button. To cancel any values you’ve entered on any page of the Utility, click
the Cancel button.
The Setup screen, shown in Figure 5-3, is the first screen you see when you
access the web-based utility. If you have already installed and set up the Router,
you have already seen this screen and properly configured all of the screen’s
values. Some options on this screen remain the same while the Internet
Connection option will change depending on how you connect to the Internet.
The main options are described first, with all of the Internet Connection types
following.
Host Name/Domain Name These fields allow you to supply a host and
domain name for the Router. Some ISPs require these names as identification.
You may have to check with your ISP to see if your broadband Internet service
has been configured with a host and domain name. In most cases, leaving these
fields blank will work.

NNTP (Network News Transfer Protocol) The protocol used to connect to
Usenet groups on the Internet.
SNMP (Simple Network Management Protocol) A widely used network
monitoring and control protocol. Data is passed from SNMP agents, which
are hardware and/or software processes reporting activity in each network
device (switch, router, bridge, etc.) to the workstation console used to over-
see the network. The agents return information contained in a MIB
(Management Information Base), which is a data structure that defines
what is obtainable from the device and what can be controlled (turned off,
on, etc.).
Enter the number of the internal port used by the server in the Int. Port col-
umn. Check with the Internet application software documentation for more
information.
Enter the IP address of the server that you want the Internet users to be able to

The Preset Applications at the top of the list are among the most widely used
Internet applications. They include the following:
FTP (File Transfer Protocol) A protocol used to transfer files over a
TCP/IP network (Internet, UNIX, etc.). For example, after developing the
HTML pages for a website on a local machine, web developers typically
upload the files to the web server using FTP. FTP includes functions to log
onto the network, list directories, and copy files. FTP operations can be per-
formed by typing commands at a command prompt or via an FTP utility
running under a graphical interface such as Windows. FTP transfers can
also be initiated from within a web browser by entering the URL preceded
by ftp://.
Telnet A terminal emulation protocol commonly used on Internet and
TCP/IP-based networks. It allows a user at a terminal or computer to log
onto a remote device and run a program.
SMTP (Simple Mail Transfer Protocol) The standard e-mail protocol on
the Internet. It is a TCP/IP protocol that defines the message format and the
message transfer agent (MTA), which stores and forwards the mail.
DNS (Domain Name System) The way that Internet domain names are
located and translated into IP addresses. A domain name is a meaningful
and easy-to-remember “handle” for an Internet address.
TFTP (Trivial File Transfer Protocol) A version of the TCP/IP FTP proto-
col that has no directory or password capability.
Finger A UNIX command widely used on the Internet to find out infor-
mation about a particular user, such as his or her telephone number, whether
the user is currently logged on, and the last time the user was logged on. The
person being “fingered” must have placed his or her profile on the system
in order for the information to be available. Fingering requires entering the
full user@domain address, for example, name@universityname.edu.
HTTP (HyperText Transport Protocol) The communications protocol used
to connect to servers on the World Wide Web. Its primary function is to
establish a connection with a web server and transmit HTML pages to the
client web browser.
POP3 (Post Office Protocol 3) A standard mail server commonly used on
the Internet. It provides a message store that holds incoming e-mail until
users log on and download it. POP3 is a simple system with little selectivi-
ty. All pending messages and attachments are downloaded at the same time.
POP3 uses the SMTP messaging protocol. (SMTP may also need to be for-
warded.)

Port Range Forwarding sets up public services on your network, such as web
servers, ftp servers, e-mail servers, or other specialized Internet applications.
(Specialized Internet applications are any applications that use Internet access
to perform functions such as videoconferencing or online gaming. Some
Internet applications may not require any forwarding.) When users send this
type of request to your network via the Internet, the Router will forward those
requests to the appropriate PC. Before using Forwarding, the Router’s DHCP
function must be disabled under the DHCP tab and the Router must be assigned
a new static LAN IP address because the IP address may change when using
the DHCP server.
If you need to forward all ports to one PC, see the “DMZ” section.
To add a Customized Application using Port Range Forwarding:
1. Enter the name of the application in the appropriate Customized
Application field.
2. Next to the name of the application, enter the number of the external port
used by the server in the Ext. Port column. Check with the Internet appli-
cation software documentation for more information.
3. On the same line, select Protocol TCP or Protocol UDP.
4. Enter the IP address of the server that you want the Internet users to be able
to access. For information about finding the IP address, go to “Appendix D:
Finding the MAC Address and IP Address for Your Ethernet Adapter.
5. Check the Enable box to enable the services you have defined. Port Range
Forwarding will not function if the Enable button is left unchecked. This is
disabled (unchecked) by default.

From the Dynamic Routing screen, shown in Figure 5-15, you can enable the
Router to automatically adjust to physical changes in the network’s layout. The
Router, using the RIP protocol, determines the network packets’ route based on
the fewest number of hops between the source and the destination. The RIP pro-
tocol regularly broadcasts routing information to other routers on the network.
To set up Dynamic Routing:
1. Choose the correct Working Mode. Gateway mode should be used if the
Router is hosting your network’s connection to the Internet. Router mode
should be selected if the Router exists on a network with other routers. In
Router Mode, any computer connected to the Router will not be able to con-
nect to the Internet unless you have another router functioning in the
Gateway mode.
2. Choose a Dynamic Routing path protocol for either transmission (TX:) or
reception (RX:) of network data by selecting Enabled.
Click the Show Routing Table button to open a chart displaying how data is
routed through your LAN.

To delete a Static Routing entry, select an entry, and click the Delete this
entry button.
2. Enter the following data to create a new static route.
Destination LAN IP: The Destination LAN IP is the address of the remote
network or host to which you want to assign a static route. Enter the IP
address of the host for which you wish to create a static route here. If you
are building a route to an entire network, be sure that the network portion
of the IP address is set to 0. For example, the Router’s standard IP address
is 192.168.1.1. Based on this address, the address of the routed network is
192.168.1.x, with the last digit “x” determining the Router’s place on the
network. Therefore you would enter the IP address 192.168.1.0 if you want-
ed to route to the Router’s entire network, rather than just to the Router.
Subnet Mask: The Subnet Mask determines which portion of an IP
address is the network portion, and which portion is the host portion. Take,
for example, a network in which the Subnet Mask is 255.255.255.0. This
determines (by using the values 255) that the first three numbers of a net-
work IP address identify this particular network, while the last digit (from
1 to 254) identifies the specific host.
Default Gateway: This IP address should be the IP address of the gateway
device that allows for contact between the Router and the remote network
or host.
Hop Count: This determines the maximum number of steps between net-
work nodes that data packets will travel. A node is any device on the net-
work, such as PCs, print servers, routers, etc. The maximum metric, or
measure, of hops is 15.
Interface: Select LAN or WA N , depending on the location of the static
route’s final destination.

The Router’s MAC address is a 12-digit code assigned to a unique piece of
hardware for identification, like a social security number. If your ISP requires
MAC address registration, find your adapter’s MAC address by following the
instructions in “Appendix D: Finding the MAC Address and IP Address for
Your Ethernet Adapter.
Enter the 12 digits of your adapter’s MAC address in the on-screen fields (see
Figure 5-18). This “clones” your Ethernet adapter’s MAC address onto the
Router, so you do NOT have to call your ISP to change the registered MAC
address to the Router’s MAC address.

RTS Threshold. This value should remain at its default setting of 2,346.
Should you encounter inconsistent data flow, only minor modifications are
recommended.
Fragmentation Threshold. This value indicates how much of the Router’s
resources are devoted to recovering packet errors. The value should remain
at its default setting of 2,346. If you have decreased this value and experi-
ence high packet error rates, you can increase it again, but it will likely
decrease overall network performance. Only minor modifications of this
value are recommended.
DTIM Interval. This value indicates the interval of the Delivery Traffic
Indication Message (DTIM). A DTIM field is a countdown field informing
clients of the next window for listening to broadcast and multicast mes-
sages. When the Router has buffered broadcast or multicast messages for
associated clients, it sends the next DTIM with a DTIM Interval value.
Clients for the Router hear the beacons and awaken to receive the broadcast
and multicast messages.
Basic Rates. The basic transfer rates should be set depending on the speed
of your wireless network. You must select 1-2 (Mbps) if you have older
802.11 compliant equipment on your network, such as wireless adapters
that support only 1 or 2 Mbps. Selecting 1-2 (Mbps), however, does not
limit the basic transfer rates of faster adapters.
TX Rates. Select all the rate at which you wish the Router to communicate
within your wireless network.
Preamble Type. The preamble defines the length of the CRC block for
communication between the Router and the roaming Network Card. (High
network traffic areas should use the shorter preamble type.) Select the
appropriate preamble type and click the Apply button to set it.
Authentication Type. You may choose between Open System, Shared
Key, and Both. The Authentication Type default is set to Open System, in
which the sender and the recipient do NOT share a secret key. Each party
generates its own key-pair and asks the receiver to accept the randomly-
generated key. Once accepted, this key is used for a short time only. Then
a new key is generated and agreed upon. Shared Key is when both the
sender and the recipient share a secret key.

Before making any changes to the Wireless tab, shown in Figure 5-19, please
check the wireless settings for all your wireless PCs, as these changes will alter
the Router’s effectiveness. In most cases, these settings do not need to be
changed.
Beacon Interval. This value indicates the frequency interval of the beacon.
A beacon is a packet broadcast by the Router to keep the network synchro-
nized. A beacon includes the wireless LAN service area, the IP address, the
Broadcast destination addresses, a time stamp, Delivery Traffic Indicator
Maps, and the Traffic Indicator Message (TIM).
