Information about Wireless Networks
A wireless network in a LAN environment, also called wireless
LAN (WLAN), is network that does not use network cables.
When a WLAN uses access points, the wireless network is
operating in infrastructure mode. In this mode, a client sends
and receives information through one or more access points.
The Intel® PRO/Wireless 2011B LAN adapter operates with
Intel® PRO/Wireless 2011B LAN access points and IEEE
802.11b compliant access points sold by other vendors.
An access point is a stationary device on an 802.11 wireless
network that receives and retransmits data. An access point
allows computers with wireless network adapters, also called
wireless clients, to be connected to typically an Ethernet
network. The Intel® PRO/Wireless 2011B LAN Access Point
is displayed in the figure below.
Identifying a WLAN
A Service Set Identifier (SSID) identifies a WLAN. There are
several kinds of SSIDs. For simplicity , th is guide uses the term
Network Name (SSID) in place of other terms such as ESSID
and IBSSID. For either an infrastructure or peer-to-peer
WLAN, the SSID indicates what WLAN you are
communicating with. When installing a wireless adapter, the
software asks you to enter this information. All devices in a
WLAN must use the same Network Name (SSID).
Security
In a WLAN, wireless clients send and receive information
through the air. Without implementing security, it is possible
for an unauthorized person to intercept the information.
Intel® PRO/Wireless 2011 B LAN Access Point Quick Installati on Guide 1
Information about Wireless Networks
A common way of implementing security and protecting
information is encryption. Before sending information over a
WLAN, the wireless device uses an encr yption ke y to scram ble
information before it is transmitted over a WLAN. The device
receiving the information uses the same key to decrypt or
unscramble the information. It is only readable to WLAN
devices that have the correct encryption key. You must use the
same key and encryption method for all wireless devices in the
WLAN. Otherwise, they cannot communicate with each other.
The network administrator provides encryption keys, either
directly or from an external key management service. The
administrator must propagate any changes to these keys to all
access points and wireless clients in a WLAN. Changing the
key on just one access point or wireless client, and without the
authority to do so, disconnects it from the rest of the network.
There are two Wired Equi valent Priv acy (WEP) encryption
methods: 40/64-bit and 128-bit. To implement security, use
either one of these methods.

The Installation Steps
The Installation Steps
Step 1: Read about the Installation
T o oper ate a WLAN in infrastructu re mode, you must install an
access point. In infrastructure mode, a wireless client sends and
receives information through one or more access points.
The Steps Outlined
Step 2: Attach regulatory compliance labels.
Step 3: Install the hardware for the Intel® PRO/Wireless
2011B LAN Access Point.
Step 4: Access the main menu for the access point software.
Step 5: View and alter the settings in the Main Menu.
For steps 2 through 5, read the subsection entitled “Before You
Start.” Failure to read this subsection could result in the adapter
not functioning in the network.
Step 2: Attach the Regulatory Compliance Label
A sheet of peel and stick regulatory compliance labels are
shipped with the adapter. F ollow the directions on the sheet and
affix the appropriate label to the adapter.
Step 3: Install the Hardware
Before You Start
In this step, install the access point. If the access point is
already installed, skip this step and proceed to step 2.
Installation Requirements
The location of each access point must be:
• Dry and dust free. Install in wet or dusty areas only with
additional protection.
• Between 0° C (32° F) and 55° C (130° F).
Intel® PRO/Wireless 2011 B LAN Access Point Quick Installati on Guide 3
The Installation Steps
Mount the Access Point
Access point coverage is similar to lighting in that an area lit
from far away might not be bright enough. Uniform access
point placement provides even, efficient coverage. Position
each access point using the following guidelines:
• Install the access point as high as practical.
• Orient the access point’s antenna vertically for best
reception.
Decide how you want to mount the access point. There are
three options.
• Resting the access point flat
• Attaching the access point to a wall
• Mounting the access point to the ceiling grid
If you are resting the access point flat, it rests on four rubber
pads on its underside. Place on a surface clear of debris and
away from office traffic.
If you are attaching the access point to a w all, use the mounting
kit provided.
Position the Antennas
The access point contains a dual antenna assembly providing
diversity, improved performance, and increased s ignal strength
over single antenna applications. If the access po int is attached
to the ceiling, point the antennas downward.
Connect the Network
Locate the connector for Ethernet on the back of the access
point. Plug the 10/100Base-T Ethernet cable into the
connector. Ethernet configurations vary according to the
environment.
If you are connecting the access point to a hub, connect the
access point to a wired UTP Ethernet hub. Normal 10Base-T
limitations apply.
If you are connecting the access point to an Ethernet switch,
ensure that the switch port parameters are set to 10 Mbps Half
Duplex. Severe performance degradation may result from
mismatched speed or duplex mode.

The Installation Steps
Connect the Power
The power adapter connects to the rear of the access point and
to a power outlet.
1. Verify that the power adapter matches the country-of-use
requirements.
2. Plug the power adapter cable into the sock et at the b ack of
the access point.
3. Plug the adapter into an outlet. The access point functions
without user intervention after setup.
If you are using an IIntel® PRO/Wireless 2011B LAN Power
Injector, see the Intel® PRO/Wireless 2011B LAN Power
Injector Quick Installation Guide for more installation
instructions.
Check the LED Indicators
Check the LED indicators to verify that the unit is functioning
correctly. Although there are six LEDs, only three are
operational. The three indicators shown left to right are:
Power L AN Wireless
After the access point is initialized, the LEDs should behave as
follows.
• The power LED should be lit.
• If the access point is connected to a LAN through an
Ethernet cable, the LAN LED should be blinking.
• If the access point is communicating with a wireless
adapter, the W ireless LED should be blinking steadily. The
Wireless LED blinks faster when the access point is
sending or receiving information from a wireless adapter.
If the access point fails to initialize, restart the access point by
disconnecting and reconnecting the power.

The Installation Steps
Step 4: Access the Access Point Main Menu
Before You Start
In this step, configure each acces s point. First, o pen the Access
Point Main Menu, and then view or alter the configuration
values. An example of a configuration value is the access
point’s Network Name (SSID). This setting is also called an
ESSID or Net_ID.
Open the Access Point Main Menu
To open the Access Point Main Menu, use one of three
methods based on the network environment. The methods to
choose from are:
• Use a Direct Serial Connection.
• Use a Telnet Connection.
• Use the Built-in Web Server.
This section briefly describes each method. For more detailed
instructions, refer to Chapter 2 in theIntel® PRO/Wireless
2011B LAN Access Point Product Reference Guide.
If you are using the Telnet or Built-in Web Server method, you
must determine the IP address of the access point first.
Determining the IP address: By default, the access point’s
factory DHCP default setting is
connected to a DHCP server, contact your network
administrator to find the access point’s IP address. Otherwise,
the default IP address is 192.0.2.1.
Enabled. If the access point is
To Use a Direct Serial Connection
1. Attach a female-to-female nine-pin serial cable from the
serial port on a computer to the Access Point 9-pin serial
connector. You must purchase the null modem serial cable
separately.
2. Launch

2. Type the admin password and press ENTER.
Telnet x.x.x.x,
The default admin password is Intel. The I is uppercase and
the remaining letters are lower case. If the access point(s) is
(are) already functioning as part of the network, the admin
password is most likely different from the default. For the
correct password, contact your network administrator.
3. Press ESC to display the Access Point Conf iguration Main
Menu. Go to step 5.
To Use the Built-in Web Server
Before continuing with the instructions below, determine the IP
address of the access point.
1. Make sure that your computer’s IP address is on the same
subnet or has access via a gateway to the s ubnet the access
point is attached to. Also make sure your proxy settings
are correct. If you are not sure, contact your network
administrator.

Step 5: View and Alter the Settings
If the access point is already functioning as part of a network,
altering its settings causes some disruption to users
communicating with the access point. If you are only viewing
information, there is no disruption to the network.
If you are configuring an access point for the first time, it is
important to alter the settings listed in table 1 below. After
altering the settings, make sure that you save them.
