CHAPTER 1: INTRODUCTION
Wireless Network
Standards
Understanding the characteristics of the 802.11a and 802.11g standards
can help you make the best choice for your wireless implementation plans.
802.11a
Ratified in 2002, 802.11a is IEEE’s more recent wireless standard. It
operates at the 5 GHz band and supports data rates at up to 54 Mbps.
Because there are fewer devices in the 5 GHz band, there’s less potential for
RF interference. However, because it is at an entirely different radio
spectrum, it is not compatible with 802.11g.
The higher spectrum provides about 50 m (164 ft) of coverage—about
half what 802.11g offers.
Consider 802.11a when you need high throughput in a confined space
and you are:
■
Running high-bandwidth applications like voice, video, or multimedia
over a wireless network that can benefit from a five-fold increase in
data throughput.
■
Transferring large files like computer-aided design files, preprint
publishing documents or graphics files, such as MRI scans for medical
applications, that demand additional bandwidth.
■
Supporting a dense user base confined to a small coverage area.
Because 802.11a has a greater number of non-overlapping channels,
you can pack more wireless devices in a tighter space.
802.11g
802.11g operates in the 2.4 GHz band at up to 54 Mbps. Ratified in
2003, it supports the widest coverage—up to 100 m (328 ft). However, is
subject to a greater risk of radio interference because it operates in the more
popular 2.4 GHz band.
802.11b operates at up to 11 Mbps and supports coverage up to 100 m
(328 ft).
Network Configuration and Planning
7
Consider 802.11g when you need wider coverage and vendor
compatibility and you are:
Network
Configuration and
Planning
■
Maintaining support for existing 802.11b users and the existing
wireless investment while providing for expansion into 802.11g.
■
Implementing a complete wireless LAN solution, including bridges,
gateways, access points and clients; Wi-Fi certification guarantees
compatibility among vendors.
■
Providing access to hot spots in public spaces such as coffee shops or
university cafeterias.
The Bridge can operate in either infrastructure or ad-hoc mode, and can
support a stand-alone wireless network configuration or an integrated
configuration with 10/100 Mbps Ethernet LANs.
Operating in infrastructure mode and connected to an Ethernet hub, a
single Bridge can combine up to 16 client devices—such as computers
with network adapters and printers—into a multiclient workgroup. The
workgroup associates with the wired network through a wireless LAN
access point such as the 3Com 11a/b/g Wireless LAN Access Point.
Infrastructure configurations extend your wireless LAN to devices that
would otherwise have to be connected to the wired network.
Operating in ad-hoc mode, two or more Bridges can associate among
themselves and communicate with one another at close range without an
access point. You may wish to set up an ad-hoc network, for example, if
a group is working away from the office, or if a group in the office needs
to share files apart from the wired LAN.

The Bridge is designed to be connected to an Ethernet client device such
as a hub, computer, or printer.
CAUTION: To avoid the possibility of a transmission loop situation between
the Bridge and an access point, which could disrupt network operation, do
not connect a Bridge that is set in Wireless Client (Infrastructure) mode
directly to the LAN (for example, through a wall port or through a hub that is
connected directly to the LAN).
About the Client List
The Bridge supports up to 16 specific Ethernet client devices. It uses a
client list of MAC addresses to keep track of specific devices that have
been connected.
After 16 different devices have been connected, the client list is full, and
you must clear it before the next new device can associate with the
network through the Bridge.
To clear the list, you must access the Bridge’s Configuration Management
System. Details are in “Clearing the Ethernet Client List” on page 46.
Connecting to a Hub
You can supply network connections for up to 16 devices, such as
computers and network printers, by connecting the Bridge to an Ethernet
hub, as shown in Figure 10.

CHAPTER 2: INSTALLING THE BRIDGE
Attaching An
External Antenna
The Bridge has two internal diversity dual-band antennas.
If you want to increase the range of the Bridge, an external antenna can
be attached to the external antenna connector on the Bridge.
The 3Com-approved external antenna for this Bridge is the
3Com 2.4/5 GHz Omnidirectional Workgroup Bridge Antenna
(3CWE501). For more information, go to www.3Com.com
Determining if you
Need to Configure
the Bridge
If your network has a DHCP server and no special security requirements,
you can most likely use the Bridge just as it is shipped from the factory.
It takes approximately one to two minutes for the Bridge to determine if
there is a DHCP server on the network.
View the Bridge’s default settings on page 20 to determine whether or
not you need to configure the Bridge for your network. If the factory
defaults meet your requirements, you can connect the Bridge as
described in “Connecting the Bridge” on page 14.
If your network does not have a DHCP server or is more complex, you
may have to configure the Bridge and organize devices so that you can
manage the wireless LAN easily and keep it secure. You can use the
3Com Wireless Infrastructure Device Manager (Widman) included on the
3Com Installation CD.
For non-U.S. versions of the Bridge, you need to set the Country mode. This is
done when you first open the Bridge’s Configuration Management System. See
“Using the Configuration Management System” on page 27 for instructions.
Networks with a DHCP Server
If your network has a DHCP server, an IP address is automatically assigned
to the Bridge. It takes approximately one to two minutes for the Bridge to
determine if there is a DHCP server on the network. Use the 3Com Wireless
Infrastructure Device Manager (Widman) included on the 3Com Installation
CD to locate the Bridge on the network and view its IP address.
Alternatively, you can enter the Bridge’s IP address into a web browser on
a computer on the same subnet to view the Bridge’s system status or
change its configuration. See “Configuring the Bridge” on page 23 for
instructions.
Determining if you Need to Configure the Bridge
19
Networks without a DHCP Server
If your network does not have a DHCP server, the Bridge uses a default
IP address (169.254.2.2) that is assigned at the factory. You can use that
IP address to configure the Bridge, or you can assign a new IP address to
the Bridge.
To verify that the Bridge is using the default IP address assigned at the
factory:
1 Connect a computer directly to the Bridge using the supplied standard
Category 5 UTP Ethernet cable.
See Figure 12 on page 16 for a connection diagram.
2 Enter the Bridge’s default IP address (169.254.2.2) into the computer’s
web browser.
■
If the Configuration Management System starts, the Bridge is using
the factory assigned IP address. You can configure the Bridge with the
following login information:
■
Login name: admin
■
Password: none (blank)
See “Configuring the Bridge” on page 23 for detailed instructions.
■
If the Configuration Management System does not start, the Bridge is
on a different subnet than the computer. Install and start the 3Com
Wireless Infrastructure Device Manager to discover the Bridge’s IP
address. See “Using the 3Com Wireless Infrastructure Device
Manager” on page 24 for instructions.

Under System Configuration, click Wireless Security. The Wireless Security
Settings page appears, where you can select the type of security to be
used on the Bridge.
The Bridge can be configured to support three types of data encryption:
WEP, TKIP, and AES. After selecting a data encryption type, you can
select an authentication type.
The following sections describe the settings. To maintain wireless
association, the settings on clients and the access points they associate
with (or other members of an ad-hoc network) must match exactly.
No Security (Open System)
No encryption is used. The network communications could be intercepted
by unintended recipients.
40/64-bit Shared Key (WEP)
This option encrypts the wireless transmissions to protect data, but still
allows communication among compatible wireless LAN clients and access
points from third-party manufacturers that are Wi-Fi certified.
This type of security requires you to set up encryption in one of the
following ways:
■
String—For use only with other 3Com 11a/b/g wireless devices, an
encryption string is a case-sensitive string of characters between 6 and
30 characters long. To enter the string, select Enter a string to
generate shared keys. Then type any combination of letters and
numbers in the space provided and select Apply.
■
Shared keys—Hexadecimal keys are sequences of hexadecimal digits
arranged into four keys. A hexadecimal digit may be a letter from
A to F or a number from 0 to 9. This type of encryption is compatible
with equipment from other manufacturers that use Wi-Fi certified
40-bit encryption. To enter the keys, select Specify shared keys and
which to use. In the shared keys window, enter all the keys in the
provided spaces, then select a radio button in the Selected Key
column to specify which key to use and select Apply.
36
CHAPTER 3: CONFIGURING THE BRIDGE
104/128-bit Shared Key
This option can be used with other 3Com 11a/b/g Wireless LAN devices
and with equipment from certain manufacturers that also support 128-bit
shared key encryption. It provides a higher level of security than the 40-bit
Shared Key (Wi-Fi) option and uses a more complicated type of encryption.
This type of security requires you to set up encryption using a string or
shared keys as described in “40/64-bit Shared Key (WEP)” on page 35.
128/152-bit Shared Key
This option can be used with other 3Com 11a/b/g Wireless LAN devices
and with equipment from certain manufacturers that also support 152-bit
shared key encryption. It provides a higher level of security than the 128-bit
Shared Key option and uses a more complicated type of encryption. This
type of security requires you to set up encryption using a string or shared
keys as described in “40/64-bit Shared Key (WEP)” on page 35.
Click the button preceding Specify Shared Keys and Which Key to Use to
create or modify WEP keys.
TKIP
The Temporal Key Integrity Protocol (TKIP) option improves data
encryption over WEP scheme by dynamically updating the encryption
keys every 10,000 packets. TKIP provides per-packet key mixing, a
message integrity check, and a re-keying mechanism.
To use TKIP:
1 On the Wireless Security page, select TKIP.
2 Select WPA-PSK for home network or WPA for the scenarios where
RADIUS servers are employed:
■

CHAPTER 3: CONFIGURING THE BRIDGE
Serial Port
Under System Configuration, click Serial Port to set up network serial port
operation.
About UART
A Universal Asynchronous Receiver/Transmitter (UART) is the
fundamental hardware for serial communication, controlling the speed
and method of data transfer of the serial port.
Applications utilizing a network serial port between an RS-232 interface
and a wireless device use a TCP/IP socket connection. Any program that
uses standard TCP/IP network sockets may be used to communicate with
the serial port of the Bridge. Once a socket is established to the Bridge,
any data written to the socket is sent out the serial port of the Bridge. At
the same time, any data received by the serial port of the Bridge is
returned via the socket connection.
The Bridge network serial port may be used in two modes:
■
Server Mode — TCP Listen Port
■
Client Mode — TCP Connect Port
In Server Mode, the Bridge waits for a TCP/IP socket connection to be
made by the network program with which it will communicate.
Server Mode should be used if you have a central server that expects to
open a TCP/IP socket connection to the Bridge.
In Client Mode, the Bridge establishes a socket connection to the
IP address and port number specified in the configuration. Client Mode
should be used if your system expects the Bridge to open a TCP/IP socket
connection to a central server.
Configuring Operation Mode
Attach your computer to the serial port on the Bridge, and then configure
the Bridge through the computer.
■
Select Enable to establish a TCP/IP socket with a remote computer in
either infrastructure or ad-hoc mode. This allows you to do data
communication with the remote computer.
■
Select Disable to disable the Network Serial Port.
Using the Configuration Management System
41
Configuring UART Settings
For proper operation, it is imperative that these settings always match the
settings of the device to which the bridge is connected via the RS-232
port. There are two groups of parameters that need to be configured to
accomplish this task: UART Settings and Flow Control Settings.
Flow control is the process of adjusting the flow of data from one device
to another to ensure that the receiving device can handle all of the
incoming data.
To configure the UART settings:
1 Select the baud rate of your device.
The baud rate indicates the data transfer rate of the serial port.
2 Determine the data bits setting of the device you are connecting to the
Bridge, then set the Data Bits setting for the bridge that matches the data
bits setting of that device.
The Data Bits setting determines the number of bits used to transmit
data. The possible values are 7 and 8.
3 Determine the stop bits setting of the device you are connecting to the
Bridge, then set the Stop Bits setting on the Bridge that matches the stop bits
setting of that device.
The Stop Bits setting determines the number of bits used to represent an
end of a character. The value can be 1 or 2.
4 Determine the parity bit setting of the device you are connecting to the
Bridge, then set the Parity Bit setting on the Bridge that matches the parity
bit setting of that device.
The Parity Bit setting is used to check for correct data transmission.
Options are: none, even, and odd.
Configuring Network Serial Port Settings
For Server Mode, click Server Mode and enter the port number to which
the Bridge connects in the List on port field. The default port number is
4000.
For Client Mode, select Client Mode and enter the IP address and port
number to which the Bridge connects. The default port number is 4000.
42
CHAPTER 3: CONFIGURING THE BRIDGE
Applying Settings
After you set the UART settings, network serial port settings, and
operation mode, select Apply to make the settings take effect.
The socket can be substantially established between a client and server;
that is, a Bridge in server mode and the other in client mode. The Bridge
with the Network Serial Port option set cannot work alone. Generally, a
Bridge is set to server mode first, which listens to a designated port. The
other Bridge is then set to client mode, which connects to the designated
port on the IP address of the Bridge set to server mode.
Resetting the Bridge
If the Bridge stops responding correctly, you can perform a reset, which
disrupts the network association temporarily, but does not affect Bridge
configuration settings that have already been applied with Apply.
To reset the Bridge, under Tools, click Reset Wireless Workgroup Bridge.
In the next page, click Reset.
The Bridge can also be reset using the Wireless Infrastructure Device
Manager (Widman). Right-click the Bridge in Widman, and then select
Reset.
Using the Configuration Management System

Disconnecting the Bridge
51
Table 15 Troubleshooting (continued)
You are running
Windows NT. After you
connect the Bridge, your
computer cannot obtain a
valid IP address.
The Bridge configuration settings may not be compatible
with the network. If they are not, and your Windows NT
computer is set up to obtain its IP address from a DHCP
server, the Bridge is unable to associate with the network
to obtain the IP address.
To work around this, set a static IP address on your
computer. Then set the Bridge configuration to match
the network. When the Bridge is able to associate,
reset your computer to obtain its IP address from the
DHCP server. If the Bridge should also obtain its IP
settings from the DHCP server, make sure this is
configured properly on the IP Network page and
applied just before ending the session.
Access to the Bridge
through Ethernet is blocked
because of incorrect
settings in the Access
Control List.
Disconnecting the
Bridge
Restore the Bridge to factory default settings (see
“Restoring the Bridge to Factory Defaults” on page 43).
The factory default setting for the Access Control List is
disabled. After the factory default settings are restored,
the Bridge can be accessed through Ethernet again.
To disconnect the Bridge:
CAUTION: Disconnecting the Bridge ends the network association. To avoid
possible data loss, exit all networking applications on connected devices before you
disconnect the Bridge.
1 Unplug the Bridge Ethernet cable from the hub or other device.
2 Unplug the Bridge power cord.

To remain in conformance with European spectrum usage laws for Wireless LAN operation, the above
2.4GHz and 5GHz channel limitations apply. The user should check the current channel of operation. If
operation is occurring outside of the allowable frequencies as listed above, the user must cease operating
the 11a/b/g Wireless Workgroup Bridge at that location and consult the local technical support staff
responsible for the wireless network.
■
The 5GHz Turbo mode feature is not allowed for operation in any European Community country.
■
This device must not be operated in ad-hoc mode using channels in the 5GHz bands in the European
Community. Ad-hoc mode provides a direct communication between two client devices without a
Wireless LAN Access Point.
■
This device must be used with Access Points that have employed and activated a radar detection feature
required for European Community operation in the 5GHz bands. This device will operate under the control
of the Access Point in order to avoid operating on a channel occupied by any radar system in the area. The
presence of nearby radar operation may result in temporary interruption in communications of this device.
The Access Point’s radar detection feature will automatically restart operation on a channel free of radar.
You may consult with the local technical support staff responsible for the wireless network to ensure the
Access Point device(s) are properly configured for European Community operation.
