area network (LAN) without the constraints and expense of network
wiring.

Enterasys Networks 802.11a/b/g Wireless LAN products provide easy,
affordable, flexible ways to extend wireless networ k s t o more users. This
guide shows how you can use the Enterasys Networks 802.11a/b/g Wireless
Ethernet Adapter in your office or classroom to connect groups of wired
Ethernet client devices to your wireless LAN.

Product Features The Enterasys Networks 802.11a/b/g Wireless Ethernet Adapter includes a

robust suite of standards-based security features, and supports wireless
network standards including 802.11a and 802.11g.

Security To protect sensitive data broadcast over the radio, Enterasys Networks

supports Wireless Equivalent Privacy (WEP) RC4 64-b i t, 128-bit and
152-bit shared-key encryption. Enterasys Networks strengthens this basic
security mechanism with additional security features, including:

■ MAC address access control lists

■ IEEE 802.1x per-port user authentication with RADIUS server

authentication support

■ Temporal Key Integrity Protocol (TKIP)

■ Advanced Encryption Standard (AES)

■ WiFi Protected Access (WPA)

■ Extensible Authentication Protocol (EAP) support: EAP-TTLS and PEAP

7 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 dif ferent radio spectr um,
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 inter fer ence because it operates in the more
popular 2.4 GHz band.

802.11b operates at up to 11 Mbps and sup ports coverage up to 100 m
(328 ft).

Network Configuration and Planning 8

Consider 802.11g when you need wider coverage and vendor
compatibility and you are:

■ 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 Ethernet

Adapters, 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.

Network
Configuration and
Planning

The Ethernet Adapter 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 Ethernet Adapter 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 Enterasys Networks 802.11a/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 Ethernet Adapters 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.

9 CHAPTER 1: INTRODUCTION

Example
Configurations

The following examples illustrate ways you can use the Ethernet Adapter to
configure Ethernet client devices into workgroups. (Details for setting up
specific configurations are in “Installing the Ethernet Adapter” on page 11.)

15 CHAPTER 2: INSTALLING THE ETHERNET ADAPTER

Connecting to an

Ethernet Device

The Ethernet Adapter 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 Ethernet Adapter and an access point, which could disrupt network
operation, do not connect a Ethernet Adapter 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).

VORSICHT: Um eine Übertragungsschleife zwischen dem
Ethernet-Adapter und einem Access Point zu verhindern, die den
Netzwerkbetrieb stören könnte, darf ein im Modus Wireless Client
(Infrastructure) (Drahtloser Client [Infrastruktur]) eingerichteter
Ethernet-Adapter nicht direkt mit dem LAN verbunden werden (z. B. über
eine Wandbuchse oder über einen direkt mit dem LAN verbundenen Hub).

About the Client List The Ethernet Adapter 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 Ethernet Adapter.

To clear the list, you must access the Ethernet Adapter’s Configuration
Management System. Details are in “Clearing the Ethernet Client List” on
page 49.

Connecting the Ethernet Adapter 16

Connecting to a Hub You can supply network connections for up to 16 devices, such as

computers and network printers, by connecting the Ethernet Adapter to
an Ethernet hub, as shown in Figure 8.

Figure 8 Connecting to a Hub

You can directly connect the Ethernet Adapter to a hub that does not have
an uplink (MDIX) port, without the need of an Ethernet crossover cable.

Attaching An
External Antenna

The Ethernet Adapter has two internal diversity dual-band antennas.
If you want to increase the range of the Ethernet Adapter, an external

antenna can be attached to the external antenna connector on the
Ethernet Adapter.

The Enterasys Networks-approved external antenna for this Ethernet
Adapter is the Enterasys Networks Range Extender Antenna, part number
RBT-AG-IA. For more information, go to

http://www.enterasys.com/products/wireless

Determining if you
Need to Configure
the Ethernet
Adapter

If your network has a DHCP server and no special security requirements,
you can most likely use the Ethernet Adapter just as it is shipped from the
factory.

It takes approximately one to two minutes for the Ethernet Adapter to
determine if there is a DHCP server on the network.

View the Ethernet Adapter’s default settings on page 22 to determine
whether or not you need to configure the Ethernet Adapter for your
network. If the factory defaults meet your requirements, you can connect
the Ethernet Adapter as described in “Connecting the Ethernet Adapter”
on page 15.

If your network does not have a DHCP server or is more complex, you
may have to configure the Ethernet Adapter and organize devices so that
you can manage the wireless LAN easily and keep it secure. You can use
the Enterasys Networks Wireless Infrastructure Device Manager (Widman)
included on the Enterasys Networks Installation CD.

For non-U.S. versions of the Ethernet Adapter, you need to set the Country
mode. This is done when you first open the Ethernet Adapter’s Configuration
Management System. See “Using the Configuration Management System” on
page 29 for instructions.

Networks with a DHCP Server

If your network has a DHCP server, an IP address is automatically assigned
to the Ethernet Adapter. It takes approximately one to two minutes for the
Ethernet Adapter to determine if there is a DHCP server on the network.
Use the Enterasys Networks Wireless Infrastructur e De vice Manag er

Determining if you Need to Configure the Ethernet Adapter 20

(Widman) included on the Enterasys Networks Installation CD to locate the
Ethernet Adapter on the network and view its IP address.

Alternatively, you can enter the Ethernet Adapter’s IP address into a web
browser on a computer on the same subnet to view the Ethernet
Adapter’s system status or change its configuration. See “Configuring
the Ethernet Adapter” on page 25 for instructions.

Networks without a DHCP Server

If your network does not have a DHCP server , the Ethernet Adapter uses a
default IP address (169.254.2.2) that is assigned at the factory. You can
use that IP address to configure the Ethernet Adapter, or you can assign a
new IP address to the Ethernet Adapter.

To verify that the Ethernet Adap ter is using the default IP address
assigned at the factory:

1 Connect a computer directly to the Ethernet Adapter using the supplied

standard Category 5 UTP Ethernet cable.
See Figure 10 on page 18 for a connection diagram.

2 Enter the Ethernet Adapt er’s default IP address (169.254.2.2) into the

computer’s web browser.

■ If the Configuration Management System starts, the Ethernet Adapter

is using the factory assigned IP address. You can co nfigure the
Ethernet Adapter with the following login information:

■ Login name: admin

■ Password: none (blank)

See “Configuring the Ethernet Adapter” on page 25 for detailed
instructions.

■ If the Configuration Management System does not start, the Ethernet

Adapter is on a different subnet than the computer. Install and start
the Enterasys Networks Wireless Infrastructure Device Manager to
discover the Ethernet Adapter’s IP address. See “Using the Enterasys
Networks Wireless Infrastructure Device Manager” on page 26 for
instructions.

CONFIGURING THE ETHERNET
ADAPTER

If the Ethernet Adapter configuration that was set at the factory does not
meet your network requirements, or if you want to customize the
settings, you can use these tools to change the configuration:

Using Secure Web
Server Connection

The Ethernet Adapter can be configured using Secure Socket Layer (SSL)
technology, which is used to encrypt data exchanged bet w ee n the
computer and the Ethernet Adapter during a configuration session.

Setting Description

Wireless LAN
Service Area

Select Attach to any WLAN Service Area (ESSID) automatically

to allow the Ethernet Adapter to associate with any access

point without specifying the ESSID. In this mode, the Ethernet

Adapter uses the ESSID of the access point with the best signal

strength. This mode is not available when the network mode is

Ad-hoc (Peer-to-Peer).

Select Specify the Wireless LAN Service Area to allow the

Ethernet Adapter to associate only with access points with the

same service area. You may enter the WLAN service area name

or select it from the list. You must specify the WLAN service

area when the network mode is Ad-hoc (Peer-to-Peer).

To maintain a wireless association, the WLAN service area on a

Ethernet Adapter and the access point with which it is

associated must match exactly. Therefore, if the Ethernet

Adapter is set to Specify the WLAN Service Area and you

change the access point WLAN service area, make sure to also

change the Ethernet Adapter WLAN service area.

Channel Selection If Radio Mode is set to Auto Select, you do not have the

following options to choose from.

When the network mode is Wireless Client (Infrastructure), a

user may have the Ethernet Adapter automatically select an

appropriate channel by using Automatic Best Channel or

specify the channels by using Specify Channel.

When the network mode is Ad-hoc (Peer-to-Peer) you may

specify channel selection as follows:

■ Automatic Best Channel—When this option is enabled, the

Ethernet Adapter scans the primary channels. If the
Ethernet Adapter is establishing a new ad-hoc network, it
chooses the channel with the least number of packets. If
the Ethernet Adapter is joining an existing ad-hoc network,
it selects the channel in use.

■ Specify Channel—Click the button preceding this option

and enter the Advanced Wireless Network page. On this
page, you can choose channels from the Channel list.

Transmit Power This option specifies the level of transmission power. Select

one of the values (100%, 50%, 25%, 12%, min) from the

Setting Up an Ad-Hoc

Network

Operating in ad-hoc mode, two or more Ethernet Adapters can associate
among themselves to form an ad-hoc network without the intervention
of 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.

CAUTION: To ensure correct operation, the settings on the two Ethernet
Adapters must match exactly. To avoid the possibility of losing wireless
association while you are configuring, Enterasys Networks recommends
that you connect the Ethernet Adapter directly to the computer.

VORSICHT: Um einen fehlerfreien Betrieb zu gewährleisten, müssen die

No Security (Open System)

No encryption is used. 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 cert ified.

This type of security requires you to set up encryption in one of the
following ways:

■ 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.

This option can be used with other Enterasys Networks 802.11a/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 secur ity requires you to set up encryption
using a string or shared keys as described in “40/64-bit Shared Key (WEP)”
on page 37.

128/152-bit Shared Key

This option can be used with other Enterasys Networks 802.11a/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 mor e complica ted 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 Shar edKey (WEP)” on

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
Ethernet Adapter . Once a socket is established to the Ethernet Adapter , any data
written to the socket is sent out the serial port of the Ethernet Adapter. At the
same time, any data received by the serial port of the Ethernet Adapter is returned
via the socket connection. The serial port communicates to the wir eless port only.
The serial port cannot communicate with the wired Ethernet port.

The Ethernet Adapter network serial port may be used in two modes:

■ Server Mode — TCP Listen Port

■ Client Mode — TCP Connect Port

In Server Mode, the Ethernet Adapter waits for a TCP/IP socket connection
to be made over the wireless port by t he ne twork program with which it
will communicate. Server mode should be used if you have a central ser ver
that expects to open a TCP/IP socket connection to the Ethernet Adapter.

In Client Mode, the Ethernet Adapter establishes socket connection over
the wireless port to the IP address and port number specified in the
configuration. Client mode should be used if your system expects the
Ethernet Adapter to open a TCP/IP socket connection to a central server.

Configuring Operation Mode

Attach your computer to the serial port on the Ethernet Adapter, and
then configure the Ethernet Adapter 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 42

Configuring UART Settings

For proper operation, it is imperative that these settings always match the
settings of the device to which the Ethernet Adapter 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

Ethernet Adapter , then set the Data Bits setting for the Ethernet Adapter that
matches the data bits setting of that device.

The Data Bits setting dete r m in es 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

Ethernet Adapter , then set the Stop Bits setting on the Ethernet Adapter 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

Ethernet Adapter , then set the Parity Bit setting on the Ethernet Adapter 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 Ethernet Adapter 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 Ethernet Adapter connects. The default port
number is 4000.

43 CHAPTER 3: CONFIGURING THE ETHERNET ADAPTER

After configuring the port mode, you also need to configure the
following options:

■ Line Length – As data arrives on the serial port it is accumulated in a

buffer in the Ethernet Adapter. The Line length parameter sets the
maximum size for this buffer. When the number of characters in the
buffer reaches the Line length value the entire buffer is sent as the
data in a single network packet.

The value of Line length can range from 1 to 1,408 bytes. The default
value is 1,408.

Do not use values of line length less than 5 with a serial baud rate of
115,200 or greater.

■ Timeout – Often serial data arrives in small bursts of characters. When

the Ethernet Adapter receives a burst of data it will wait for a certain
period of time for additional data to be received. If additional data is
received, it is added to the receive buffer, and the Ethernet Adapter
begins to wait again. If additional data is not received for longer than
the period specified by the Timeout value, then the buffer of
characters received is sent in a single network packet, and the process
begins again.

The value of timeout is in units of milliseconds, and should be specified in
10 millisecond increments. The valid range for timeout is from 10 (0.01
second) to 65,000 (650 seconds). The default value is 10.

■ Delimiters – Some serial devices transmit and receive data in a known

structure. In these cases, there are often special characters that the
transmitting device uses to indicate a complete message has been
sent. These characters are referred to as delimiters. You can specify up
to five different delimiting characters to the Ethernet Adapter. When
the Ethernet Adapter adds one of these characters to its buffer of
serial received characters, it will immediately send that buffer as a
network packet.

The value of delimiters is specified as a list of hexadecimal values
separated by spaces. You may specify up to five differ ent delimiter
values. For example, if you want to use the delimiter 41375, you must
type the following hex values:

0x34 0x31 0x33 0x39 0x35

If you are unsure of the hex value for your delimiter character, consult
the Web page www.asciitable.com for reference.

Disconnecting the Ethernet Adapter 52

Disconnecting the
Ethernet Adapter

To disconnect the Ethern et Adapter:

CAUTION: Disconnecting the Ethernet Adapter ends the network
association. To avoid possible data loss, exit all networking applications on
connected devices before you disconnect the Ethernet Adapter.

VORSICHT: Wird die Verbindung des Ethernet-Adapters getrennt, wird
damit auch die Netzwerkverbindung unterbrochen. Zur Vermeidung von
eventuellen Datenverlusten müssen alle Netzwerkanwendungen auf
verbundenen Geräten beendet werden, bevor die Verbindung des
Ethernet-Adapters getrennt wird.

1 Unplug the Ethernet Adapter Ethernet cable from the hub or other

device.

2 Unplug the Ethernet Adapter power cord.

Symptom Solution(s)

You are running Windows NT.
After you connect the
Ethernet Adapter, your
computer cannot obtain a
valid IP address.

The Ethernet Adapter 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 Ethernet Adapter 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 Ethernet Adapter
configuration to match the network. When the
Ethernet Adapter is able to associate, reset your
computer to obtain its IP address from the DHCP
server. If the Ethernet Adapter 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 Ethernet
Adapter through Ethernet is
blocked because of incorrect
settings in the Access Control
List.

Restore the Ethernet Adapter to factory default settings
(see “Restoring the Ethernet Adapter to Factory Defaults”
on page 45). The factory default setting f or the Access
Control List is disabled. After the factory default settings
are restored, the Ethernet Adapter can be accessed
through Ethernet again.
