External Components
This section describes the back and front panels of the Wireless Gateway in details.
BackPanel
Following are explanations of the items on the Wireless Gateway's back panel:
•Antennae: The antennae at the back panel carry radio-frequency signals
between wireless stations and the Wireless Gateway's wireless bridge (the
interface between the wireless and wired parts of the LAN).
•Reset button: Reset will be initiated when the reset button is pressed once and
the LPT LED begins to flash. Factory Reset will be initiated when the reset
button is pressed continuously for three seconds or when the LPT LED begins
to light up. Release the reset button and the LPT LED will begin to flash
indicating the Wireless Gateway is changing to factory reset. When factory
reset is completed the Wireless Gateway will be set to default on channel 11
with default IP address as 192.168.0.254 and EES-ID is set as ‘default’.
•DC Input: For connection to the DC 5V power adapter.
•Uplink port: For connecting the Wireless Gateway to an upstream hub or
switch with an ordinary “straight-through” (as opposed to cross-wired)
Ethernet cable. This port and the LAN port next to it cannot be used at the
same time; they are simply differently wired ports for LAN port 1.

8
Note: All connections to the Wireless Gateway's LAN ports
should be made with Category 5 Ethernet cabling. Lower-grade
cabling cannot reliably carry 100-Mbps signals.
•LAN ports 1 through 4: Switched, auto-negotiating 10/100-Mbps Ethernet
ports for connecting end nodes (or downstream hub-or switched-based
clusters of end nodes) to the Wireless Gateway.
•WAN port: 10-Mbps Ethernet port for connection to a DSL or cable modem
or router.
•Parallel port: A Centronics-type connector for a standard printer cable.
Front Panel
The Wireless Gateway's LED indicators are located on the unit's front panel:
•Power: Illuminates whenever the unit has power.
•Wireless: Illuminates when the wireless AP (access point) is ready but idle;
flashes when there is activity on the wireless link.
•LAN 1 to LAN 4 Link/Act: Each of these indicators illuminates when there is
a good but idle link on the corresponding LAN port, flashes when packets are
received/transmitted on the link.
•LAN 1 to LAN 4 100M: Each of these indicators illuminates when the
corresponding LAN port is operating at 100 megabits per second.
•WAN Link: Illuminates when there is a good link on the WAN port.
•WAN Act: Illuminates whenever unit has power, flashes when there is
activity on the WAN port.
•LPT: Flashes three times then goes off to indicate a successful Power-On
Self-Test. Flashes on and off later during normal operation when there’s
printing activity. If the self-test detect any component error, thenthe LPT LED
will continuously signal the error according to the following table. In the
event of any such error signal, contact your dealer for correction of the faulty
unit.

Web Configuration
The Wireless Gateway must be configured through its built-in Web-based
configuration utility. Before attempting to access this utility, note the following
factory defaults:
•WAN interface defaults: IP address 192.168.100.254, address mask
255.255.255.0. DHCP (Dynamic Host Configuration Protocol) client and
PPPoE (Point-to-Point Protocol over Ethernet) functions are off.
•LAN interface defaults: IP address 192.168.0.254, address mask
255.255.255.0. DHCP server function is on and will assign addresses in the
range of 192.168.0.101 through 192.168.0.150.
•General defaults: No administrator password is set. Requests received
through the WAN port (including “ping” requests and HTTP requests to the
built-in Web-based configuration utility) are disabled.
The requirements for configuring the Wireless Gateway are (1) a computer equipped
with an Ethernet interface and a recent, frames-capable, Javascript-enabled World
Wide Web browser, and (2) an Ethernet cable.
You will also need extensive knowledge of the LAN and the broadband link that the
Wireless Gateway will be connected to.
The recommended way to connect the Wireless Gateway for configuration is as
follows:
1. Connect the computer to one of the LAN ports on the back panel of the
Wireless Gateway's LAN ports with the Ethernet cable (NOT the uplink port).
Do not make any other connections to the Wireless Gateway.
2. Set the computer to use an IP address in the range of 192.168.0.1 through
192.168.0.253 and an address mask of 255.255.255.0.

11
Note: If the operating system or the browser is set to use an
HTTP proxy server, either turn off the setting or put the
Wireless Gateway's IP address in the list of unproxied hosts.
3. Power up the Wireless Gateway and wait about 15 seconds while it boots up.
4. Command the browser to access the following URL:
http://192.168.0.254/
Note: If you have accessed the configuration utility and changed the IP address of
the Wireless Gateway before, use the factory reset button to reset the unit. Or
alternatively, you can enter the new IP address as the URL and make sure the
computer use a corresponding IP address. For example, if you have changed the
IP address to 172.16.100.1, use it as the URL and make sure the computer have an
IP address in the range of 172.16.100.2 through 172.16.100.254. In addition, if
you have changed the subnet mask, the computer must have the same subnet mask
too.
The configuration utility's initial display will appear and divide the browser window
into three sections:
•A menu bar at the top of the window contains the names of the utility's
top-level menus. This bar never changes.
•A command panel at the left edge of the window contains the commands in
the current menu.
•A settings panel occupying the rest of the window contains either buttons,
input boxes, and other controls for changing device settings, or information
about the Wireless Gateway.
The following sections explain the items in the settings panels under each of the
configuration utility's menus.

12
Basic Setup
The settings panels under the Basic Setup menu contain settings that almost always
must be adjusted to let the Wireless Gateway operate at all. Four settings panels can
be accessed from the Basic Setup menu:
•Broadband Router
•Wireless AP
•Print Server
•Admin Password

13
Basic Setup —Broadband Router
The Basic Setup menu's Broadband Router panel is the first to appear whenever the
configuration utility starts up. The controls in this panel are explained below.
Router Name
The Router Name is a text string that some ISPs require as a means of
identification. The setting is ignored if the ISP does not require it. It is most
often required on DHCP-based links, where it is sometimes referred to as the
DHCP client's (that is, the Wireless Gateway's) “host name.” If the ISP
requires this item, click in the Router Name input box and enter the correct
name as shown in the materials received from the ISP.
Local LAN

14
The Local LAN settings are the IP address and subnet mask that will identify
the Wireless Gateway to the other machines on your LAN. The address must
be unique on the LAN, that is, assigned exclusively to the Wireless Gateway;
the subnet mask must be the same for all machines on the LAN that will
communicate directly with the Wireless Gateway. Be sure to keep a record
of the address you set here. This will be the “default gateway” for other
machines on the LAN.
Before setting IP addresses, note that no machine must ever be assigned an
address ending in zero (that is, x.x.x.0) or 255. An IP address ending in zero
identifies an entire network, not a particular machine. An IP address ending in
255 is a “broadcast” address, used for sending messages to all the machines on
a network at the same time.
Note also that possible subnet mask settings for the LAN interface are of the
form 255.255.255.x, where x can be 0, 128, 192, 224, 240, 248, or 252. The
installing technician will recognize that this makes the Local LAN settings
suitable for a Class C IP network or a subnet of such a network.
In the case that ISP give you a single globally legal IP address to be assigned
to the Wireless Gateway's WAN port, you will have to use what are called
“private addresses” on the LAN.
An example of a private address is 172.16.0.0. This is a network address;
individual machines on a LAN using this network address can be assigned
addresses in the range of 172.16.0.1 through 172.16.0.254. (This assumes that
all machines on the LAN use a subnet mask of 255.255.255.0; using any other
mask requires extensive technical knowledge and is beyond the scope of this
guide.)
The following three IP address blocks have been set aside by Internet
regulatory authorities specifically for local-only use:
10.0.0.0 through 10.255.255.255
172.16.0.0 through 172.31.255.255
192.168.0.0 through 192.168.255.255
Global WAN Mode

15
The Global WAN Mode controls must be adjusted as required by your ISP.
The settings you enter here determine how the Wireless Gateway will be
identified to your ISP's equipment and other machines on the global Internet.
•If your ISP has given you a fixed IP address to use on the WAN link,
click the Specify Global IP Address control. Then click in (or tab to)
the three boxes below it and type in the global IP address, subnet mask,
and default gateway that the ISP has instructed you to use.
•If your ISP will assign the Wireless Gateway an IP address and related
settings using DHCP (the Dynamic Host Configuration Protocol),
simply click Obtain Global IP Address Automatically (DHCP).
DHCP is commonly used on cable links.
•If your ISP uses PPPoE (the Point-to-Point Protocol over Ethernet),
click the PPP over Ethernet (PPPoE) control. The ISP will have
given you a “username” or user ID and a password to use on the
PPPoE link; click in (or tab to) the corresponding boxes under this
control and type in the strings your ISP has instructed you to use. In
some cases —especially if the Wireless Gateway's WAN port is
networked directly to more than one broadband modem or router —
you will need to type an identifying string into the Service Name box.
Your PPPoE link might allow you to save on connection charges by
disconnecting when the link is not in use and reconnecting when
someone on the LAN wants to access the Internet. If this is the case,
you have the option of setting the Connect on Demand control to Yes
or No. If you click No, you will have to use the PPPoE Connectand
PPPoE Disconnect commands in the Tools menu to take the Wireless
Gateway on line and off line. (You can, alternatively, use the Manager
Server software to set a connection schedule; see the Manager Server
manual for details.) If you click Yes, be sure to set the Maximum Idle
Time control also. The Wireless Gateway will then automatically
disconnect whenever the specified amount of time passes without
anyone on the LAN accessing the Internet.
DNS IP Addresses
In almost all cases your ISP will provide you with the IP addresses of two or
more DNS (Domain Name System) servers. Click in the boxes provided and
type in the addresses carefully. If you set the Wireless Gateway up as a DHCP

16
server for the machines on your LAN, it will pass the addresses to those
machines as part of the automatic configuration process. (If the Wireless
Gateway will not act as a DHCP server, you might need to set the DNS server
addresses on each of the machines individually.)
WAN Port MAC
A MAC (Media Access Control) address is a globally unique identifier for an
Ethernet interface. In cases where the Wireless Gateway is a replacement for a
computer or router with an existing broadband connection to an ISP, you
might need to make the Wireless Gateway use the same MAC address as the
device it replaces.
The original device should have a label with the device's MAC address printed
on it. A MAC address is ordinarily written as twelve hexadecimal digits, with
or without separating spaces —for example, 0080C82F8086, 0080C8 2F8086,
or 00 80 C8 2F 80 86 (these are all different ways of writing the same address).
Only the numbers 0 through 9 and the letters A through F can appear in a
hexadecimal MAC address. Letters can be in upper or lower case;
0080c82f8086 is the same as 0080C82F8086.
Only if it is necessary to do so, click the Use New MAC Address button, and
then click in the box provided and carefully type the original device's MAC
address.
Save/Cancel
After making sure all settings in the Broadband Router panel are correct, click
Save to store the settings in the Wireless Gateway's non-volatile memory. You
can, alternatively, click Cancel (or simply exit the panel) to restore all settings
in the panel to the values last saved to or retrieved from the Wireless Gateway.
Note: If you have changed the IP address in the Wireless
Gateway's Local LAN settings, be sure, after you click Save, to
point your browser to the Wireless Gateway's new IP address
before going on.
This completes the basic setup of the Wireless Gateway as a router. You are now
ready to carry out the basic setup of the Wireless Gateway's other important functions.

17
Basic Setup —Wireless AP
The Wireless Gateway's “wireless AP” is the access point —the radio-frequency
transmitting and receiving circuitry —through which wireless devices will
communicate with your LAN's wired devices and the Internet. To begin setting up the
wireless AP, click Wireless AP in the command panel at the left edge of your
browser window (if the command does not appear there, click Basic Setupat the top
of the window first).
ESS-ID
“ESS-ID” (or “ESSID”) stands for Extended Service Set ID. This is an
identifier for the network segment made up of the Wireless Gateway's wireless
AP and the wireless stations that will communicate with it. Click in the
ESS-IDbox and type any string up to 32 characters long (spaces, symbols,
and punctuation are not allowed). The same string must be set as the ESS-ID
on each wireless station that will use the Wireless Gateway as an access point.
Wireless Channel
A “channel” is a range of frequencies to be used in communication between an
AP and wireless stations. The number of channels available on the Wireless
Gateway depends on the regulatory region in which the unit was sold.

18
If the Wireless Gateway is the only AP on your LAN, it does not matter which
channel you set the unit to use; properly configured 802.11b wireless stations
will find the correct channel automatically.
Where there are multiple APs with overlapping coverage areas, channel
assignment must be carefully planned. A good practice is to set the Wireless
Gateway to use a channel five or more channels away from that of any other
AP with a coverage area overlapping that of the Wireless Gateway. A
common scheme is to use channels 1, 6, and 11, making sure that no two APs
using the same channel have overlapping coverage areas.
Tx Bit Rate
The Tx (transmission) Bit Rate is the speed at which wireless stations and an
AP communicate. The choices are 1, 2, 5.5, and11 Mbps (megabits per
second), and Fully Automatic. The default setting is Fully Automatic. A
setting of Fully Automatic allows stations and the AP to adjust their speed on
the basis of signal strength and quality. A low, fixed setting might be used for
maximum reliability or to discourage the use of high-bandwidth applications
such as video and audio. A high, fixed setting will fasten the transmission
speed and ensure that only stations very close to the AP will be able to
communicate reliably with it.
Save/Cancel
After making sure all settings in the Wireless AP panel are correct, click Save
to store the settings in the Wireless Gateway's non-volatile memory. You can,
alternatively, click Cancel(or simply exit the panel) to restore all settings in
the panel to the values last saved to or retrieved from the Wireless Gateway.

19
Basic Setup —Print Server
To view and adjust the Wireless Gateway's print server settings, click Print Server in
the command panel at the left edge of your browser window (if the command does not
appear there, click Basic Setup at the top of the window first). Controls in the Print
Server settings panel are explained below.
Print Port
The Print Port Speedcontrol has two possible settings, Highand Low. The
default setting is High,which is preferable for most modern printers. Change
the setting to Lowonly if your printer is antiquated and prints incorrectly at a
High setting.
TCP/IP
The Print Server TCP/IP settings include the IP address and subnet mask used
by the Wireless Gateway on the LAN. These are set through the Broadband
Router settings panel and displayed in the Print Server panel for informational
purposes only. The Print Server panel also shows the Raw Send Port, an
unchangeable setting used by Microsoft Windows 2000 for network-based
printing.
AppleTalk

20
Machines running the Macintosh OS on your LAN can print on a PostScript
printer attached to the Wireless Gateway. When such machines request
information about network printers using the AppleTalk protocol, the Wireless
Gateway will respond with the information shown in the Print Server panel.
This information must be correct for successful printing.
The Zone Name is a text string identifying a group of devices using
AppleTalk on a LAN. These devices can be concentrated in one area or
scattered throughout the network. Ordinarily an asterisk [*] initially appears in
the Zone Name box; this can represent “the local zone” (whatever its name
might be), or it can mean that no zones are configured. If AppleTalk zones are
configured on the network, click in the Zone Name box and type the name of
the zone you want the printer to belong to.
Chooser Name is the name the Wireless Gateway will use for the printer
when reporting its presence to machines running the Macintosh OS. The
Wireless Gateway will construct a default name from the name given to the
broadband router in basic setup, but you can change it to any text string you
like.
The Printer Type is a text string that tells the Macintosh which driver to use
for the printer. For a PostScript printer this should almost always be
LaserWriter. This is the default value.
The PostScript Level can be 1or 2. Unless the printer is a very old model, a
setting of Level 2 should work best.
The Font Groupsetting tells the Macintosh how many PostScript fonts the
printer has built in. All but the oldest PostScript printers can safely be assumed
to have the “Standard 35” PostScript fonts.
Save/Cancel
After making sure all settings in the Print Server panel are correct, click Save
to store the settings in the Wireless Gateway's non-volatile memory. You can,
alternatively, click Cancel(or simply exit the panel) to restore all settings in
the panel to the values last saved to or retrieved from the Wireless Gateway.
