Inserting and Removing a Client Adap ter

This section provides in struct ions for in ser ting a nd rem oving PC card s, PC-C ar dbus cards, a nd PCI
cards. Instructions ar e not provide d for LM card s and mini PCI cards because they are pre- install ed
inside computing devices a nd ar e not me ant to be i nsta ll ed or r emoved by the u ser.

Caution These procedures a nd the physic al c onn ect ions they de scri be a pp ly g en erall y t o

conventional PC card slots, Cardbus slots, and PCI expansion slots. In cases of custom or
nonconventional equipment, be ale rt to possi ble difference s in PC c ard sl ot, Car dbus slot,
and PCI expansion slot configurations.

Inserting a Client Adapter

Follow the instructions in one of the sections below to insert a PC card, PC-Cardbus card, or PCI card
into a computing device.

Chapter8 Routine Procedures

Inserting a PC Card or PC-Cardbus Card

Step 1 Before yo u begin, examine th e card. O ne end has a dua l-row, 68-pin connector. The card is keyed so it

can be inserted only on e way int o t he PC c ard s lot or Card bus slot.

Note The PC card slot o r Cardbus sl ot is on the le ft o r r ight sid e of the com pute r,

depending on th e mod el .

Step 2 Follow the instructions below for your specific operating system:

• Windows 95, Windows 98, Windows 2000, Windows Me, or Windows XP– Turn on your

computer, let th e operating system boot up completely , and follow the remaining steps in this section
to insert the card.

• Windows NT – Turn off your comput er , follo w the remain ing steps in this secti on to insert the card ,

and reboot your compu ter.

Caution Do not force the card into your computer’s PC card slot or Cardbus slot. Forcing it will

damage both the card and the slot. If the card does not insert easily, remove the card and
reinsert it.

Step 3 Hold the card with the Cisco logo faci ng up and insert it into the PC card slot or Cardbus slot, applying

just enough pressure to make sure it is fully seated (see Figure 8-1).

Removing a PCI Card

Because PCI client adapters are installed inside desktop compu ters, which are not designed for portable
use, you should have little reason to remove the adapter. However, instructions are provided below in
case you ever need to remove your PCI card.

Step 1 Comple tely shut down your compu ter.
Step 2 Discon nect the c lient ada pter’s antenn a.
Step 3 Remove th e co mpu ter c over.
Step 4 Remove the screw from the top of the CPU back panel above the PCI expansion slot that holds your client

adapter.

Step 5 Pull up firmly on the client adapter to release it from the slot and carefully tilt the adapter to allow it to

clear the openi ng in the CPU ba ck pane l.

Step 6 Reinstal l the scr ew on the CPU back panel and replace th e comp uter cover.

option during installation. If you wish to remove this icon from your desktop, right-click the ico n, clic k
Delete, and click Yes to confirm your decision.

Restarting the Client Adapter

ACU enables you to re-initialize (or restart) the client adapter without having to reboot your computer
or eject and reinsert the adapter. For instance, if your client adapter is experiencing poor throughput, you
might want to restart the client adapte r to try to force it to disassociate from the access point to which it
is currently associated in the hope that it will reassociate to an access point with a stronger signal.

Note Restartin g the cli ent a dapt er m a y ca use yo u to l ose your wire le ss net work c onne ction .

Step 3 When promp ted to con firm your decisi on, click Yes. The driver stops the client adapter’s radio, writes

the configuration (although no parameter settings have been changed), and restarts the radio. The status
bar at the bottom of the ACU screen shows the client adapter losing association and then reassociating.

Turning Your Client Adapter ’s Radio On or Off

Your client adapter’s radio can be turned on or off. Turning the radio off prevents the adapter from
transmitting RF energy. You might want to turn off the client adapter’s radio when you are not
transmitting data and want to conse rve battery power or when you are using a laptop on an ai rplane and
want to prevent the adapter’s transmissions from potentiall y interfering w ith the opera tion of certa in
devices.

When the radio is on, it periodically sends out beacons even if it i s not associated to an access point, a s
required by the 802.11 specification. There fore, it is impo rtant to turn it off around devices that are
susceptible to RF interference.

Note Your client adapter is not associated while the radio is off.

OL-1394-03

Follow the instructions below to turn the client adapter’s radio on or off.

• If your client a dapt er ’s radio is on, opening ACU and selecting Radio Off from the Commands

Problems Associating to an Access Point

Follow the instructions below if your client adapter fails to associate to an access point.

• If possible, move your workstation a few feet closer to an access point and try again.

• Make sure the client adapter is securely inserted in your computer’s client adapter slot.

• If you are using a PCI client adapter, make sure the antenna is securely attached.

• Make sure the access point is turned on and operati ng.

• Check that all parameters are set properly for both the client adapter and the access point. These

include the SSID, EAP authentication, WEP activation, network type, channel, etc.

• Follow the instructions in the previous section to resolve any resource conflicts. If you are using

Windows NT, you may also want to try disabling the Ethern et port.

• If the client adapter still fails to establish contact, refer to the “Obtaining Technical Assistance”

section in the Preface for techni cal support informat ion.

Problems Authenticating to an Access Point

If your client adapter is a 40-bit card and LEAP or EAP is enabled, the adapter can associate to but not
authenticate to acc ess poi nts us in g 12 8-b it enc ry ption. To authenticate to an a cce ss poin t usi ng 128- bit

• Purchase a 128-bit client adapter. This is the most secure option.

• Disable static WEP fo r th e client adap ter an d conf ig ure th e ad apter an d the acces s poi nt to a ssoci ate

to mixed cells. This option presents a security risk because your data is not encrypted as it is sent
over the RF network.

Varoitus

Attention

In order to comply with RF exposure limits established in the ANSI C95.1 standards, it is
recommended when using a laptop with a PC card client adapter that the adapter’s integrated
antenna is positioned more than 2 inches (5 cm) from your body or nearby persons during
extended periods of transmitting or operating time. If the antenna is positioned less than 2
inches (5 cm) from the user, it is recommended that the user limit exposure time.

In het kader van een in de ANSI C95.1 norm vastgelegde limiet voor blootstelling aan straling
veroorzaakt door radiofrequenties, dient u bij langdurig gebruik van een laptop met client
adapter pc-kaart een afstand van meer dan 5 centimeter aan te houden tussen de geïntegreerde
antenne van de adapter en uzelf en enige andere personen. Als deze afstand niet kan worden
aangehouden, dient u de tijd dat het apparaat gebruikt wordt te beperken.

ANSI C95.1 -standardin radiotaajuuksille asettamien altistumisrajojen mukaisesti on
suositeltavaa, että käytettäessä kannettavaa tietokonetta, jossa on PC-kortti-asiakas-adapteri,
adapterin integroitu antenni on käännetty yli viisi cm pois vartalosta tai lähellä olevist a
henkilöistä pitkäaikaistenlähetys- tai käyttöjaksojen aikana. Jos antenni on käännetty alle viisi
5 cm käyttäjästä, on suositeltavaa, että käyttäjä rajoittaa altistumisaikaa.

Afin de respecter les limitations en matière d’exposition aux fréquences radioélectriques
définies par les normes ANSI C95.1, il est recommandé aux utilisateurs d’ordinateurs portables
dotés d’adaptateurs client pour carte PC ou aux personnes se trouvant à proximité de se placer
à plus de 5 cm de l’antenne de l’adaptateur l ors de longues périodes de transmission ou de
fonctionnement. Si l’utilisateur se trouve à moins de 5 cm de l’antenne, il est préférable de
limiter le temps d’exposition.

In Übereinstimmung mit den in den Sicherheitsstandards ANSI C95.1 verzeichneten
Höchstwerten für den Kontakt mit Radiofrequenz (RF) wird f ür die Benutzung eines Laptops mit
PC-Adapterkarten für Clients empfohlen, bei längerer Inbetriebnahme oder Datenübertragung
die integrierte Antenne des Adapters mindestens 5 cm vom Benutzer und ander en sich i n der
Nähe aufhaltenden Personen entfernt aufzustellen. Befindet sich die Antenne weniger als 5 cm
vom Benutzer entfernt, sollte die Benutzungsdauer des Geräts eingeschränkt werden.

In conformità con i limiti sull’esposizione a frequenze radio stabiliti nelle direttive ANSI C95.1,
quando si utilizza un computer portatile con una scheda PC dotata di adattatore client è
consigliabile mantenere l’antenna integrata dell’adattatore a più di 5 cm di distanza durante
periodi di esposizione prolungati. Se l’antenna è posizionata a meno di 5 cm di dist anza
dall’utente, è consigliabil e limitare i tempi di esposizione alle frequenze.

Du må overholde begrensningene for RF-eksponering som er fastsatt i ANSI C95.1-standardene.
Derfor anbefaler vi, når du bruker en bærbar PC med et klientkort i PC-format, at kortets
innebygde antenne plasseres mer enn 5 cm fra deg eller personer i nærheten under lengre
perioder med overføring eller bruk. Hvis antennen er plassert mindre enn 5 cm fra brukeren,
anbefaler vi at brukeren begrenser eksponeringstiden.

Overview

BETA DRAFT - CISCO CONFIDENTIAL

Overview

This chapter provides instructions for minimally configuring the client adapter through Windows XP
(instead of through ACU) as well as for enabling one of the three security options that are available for
use with this operating system. The “Overview of Security Features” section below describes each of
these options so t hat you ca n make a n info rm ed dec is ion b ef ore you begin th e c onfigurat ion p roc ess.

In addition, the chapte r also provides ba sic informa tion on using Windows XP to specify the networks
to which the c lie nt ad ap ter a ssociat e s and t o v iew the cu rr ent stat us of y our clie nt ad ap ter.

Note If you requi re more info rmat ion abou t configuring or using your client adapter w ith Windows XP,

refer to Microsoft’s documentat ion for Windows XP.

Overview of Security Featu res

When you use your client adapter with Windows XP, you can protect your data as it is transmitted
through your wireless network by encr ypting it through th e use of Wired Equivalent Privacy (WEP)
encryption keys. With WEP encryption, the transmitting device encrypts each packet with a WEP key,
and the receiving device uses that same key to decrypt each packet.

The WEP keys used to encrypt and decrypt transmitted data can be statically associated with your
adapter or dynamically created as part of the EAP authentica tion process. The informat ion in the “Static

WEP Keys” and “EAP (with Static or Dynam ic WEP Keys)” sections be low can h elp yo u t o de c ide

which type of WEP keys you want to use. Dynamic WEP keys with EAP offer a higher degree of security
than static WEP keys.

Appendix E Configuring the Client Adapter through Windows XP

WEP keys, whether static or dynamic, are either 40 or 128 bits in length. 128-bi t W EP k ey s o f fe r a g r ea te r
level of security than 40-bit WEP keys.

Static WEP Keys

Each device within you r wire le ss n etwork ca n be a ssigne d up t o four sta tic WEP keys. If a device
receives a packet that is not encrypted with the appropriate key (as the WEP keys of all devices that are
to communicate with each other must match), the device discards the packet and never delivers it to the
intended receiver.

Static WEP keys are write-only and temporary; therefore, they cannot be read back from the client
adapter and they are lost when power to the adapter is removed or the Windows device is rebooted.
Although the keys are temporary, you do not need to re-enter them each time the client adapter is inserted
or the Windows device is rebooted. Th is i s beca use th e keys are st ored (in an e ncry pt ed f orm at for
security reasons) in the registry of the Windows device. When the driver loads and reads the client
adapter’s registry parame ters, it also find s the s tat ic WE P keys, une ncryp ts t hem, a nd stor es them i n
volatile memory on the adapter.

EAP (with Static or Dynamic WEP Keys)

The new standard for wireless LA N securit y, as defined by the Institute of Electrical and Electr onics
Engineers (IEEE), is called 802.1X for 802.11, or simply 802.1X. An access point that supports 802.1X
and its protocol, Extensi ble Auth entica tion Protoc ol (EAP) , acts as th e interfac e betwee n a wireless
client and an authentication server, such as a Remote Authentication Dial-In User Service (RADIUS)
server, to which the access point communicates over the wired network.

Two 802.1X authentic ation t ypes a re available wh en c onfiguring you r clie nt a da pte r th rou gh
Windows XP:

• EAP-TLS – Thi s a uthe nti c ation ty pe is en ab led t hr ough t he oper at ing s yst em a nd us es a dy nami c,

session-based WEP key, which is derived from the client adapter and RADIUS server, to encrypt
data.

RADIUS servers that suppor t E A P-TLS incl ude Ci sco Se cure ACS version 3.0 and gr eate r and
Cisco Access Registrar versio n 1 .8 a nd grea ter.

Note EAP-TLS requires the use of a certificate. Refer to Microsoft’s documentation for

information on downloading and installing the certificate.

• EAP-MD5 – This authentication type is enabled through the operating system and uses static WEP

to encrypt data. EAP-MD5 requires you to enter a separate EAP username and password (in addition
to your standard Windows network login) in order to start the EAP authentication process and gain
access to the network.

Note If you want to authenticate without encrypting the data that is transmitted over your

network, you can use EAP-MD5 without static WEP.

Overview

RADIUS servers that su pport EA P-MD5 incl ude Cisco Se cu re ACS version 3.0 and gr eat er and
Cisco Access Registrar versio n 1 .8 a nd grea ter.

When you enable Require EAP on your access point and configure your client ada pter for EAP-TLS or
EAP-MD5 using Windows XP, authentication to the network occurs in the following sequence:

1. The client adapter associates to an access point and begins the authentication process.

Note The client does not gain access to the network until mutual authentication between the

client and the RADIUS server is successful.

2. Communicating through the access point, the client and RADIUS server complete a mutual

authentication pro cess, wi th the pass word (for EAP- MD5) or ce rtificate (f or EAP-TL S) being th e
shared secret for authentication. The passw ord or certif ic ate is ne v er transmitte d during the process.

Note The authentication process is now complete for EAP-MD5. For EAP-TLS, the process

continues.

3. If mutual authentication is successful, the client and RADIUS server derive a dynamic,

session-based WEP key that is unique to the client.

4. The RADIUS server transmits the k e y to the acc ess poin t u sing a sec ure c hannel on the wir ed LAN.

5. For the length of a session, or time period, the access point and the client use this key to encrypt or

decrypt all unicast packet s that travel betwee n them.

Step 10 Select the Network Authentication (Shared mode) checkbox if you want to use shared key, rather than

open, authentication with the access point.
Open authentication allows your client adapter, regardless of its WEP settings, to authenticate and

attempt to communicate with an access point.
Shared key authentication allows your client adapter to communicate only with access points that have

the same WEP key. Cisco recommends that shared key authentication not be used because it presents a
security risk.

the best placement of infrastructure devices within a wireless network.

ACU’s site survey tool can assist you in co nduct ing a site sur vey. The tool operates at the RF l evel and
is used to determine the best placement and coverage (overlap) for your network’s infrastructure de vices.
During a site survey, the current statu s of the netw o r k is read from the client adap ter and dis p la ye d f ou r
times per second so you can accurat ely gauge network performance. The fe edback that you receive can
help you to eliminate areas of low RF signal levels that can result in a loss of connection between the
client adapter and its associated access point (or other infrastructure device).

The site survey tool can be operate d in two mode s:

• Passive Mode – This is the default site survey mode. It does not initiate any RF network traffic; it

simply listens to the traffic that the client adapter hears and displays the results. Follow the
instructions in the “Using Passive Mode” section on pa ge F-3 to activate the passive mode.

• Active Mode – This mode causes the client adapte r to ac ti v ely send or r ecei v e low-lev el RF p acke ts

to or from its associated access point and provides information on the success rate. It also enables
you to set parameters governing how the site survey is performed (such as the data rate). Follow the
instructions in the “Using Active Mode” section on page F-7 to activate the active mode.

Guidelines

Keep the following guidelines in mind when preparing to perform a site survey:

• Perform the site survey when the RF link is functioning with all other systems and noise sources

operational.

• Execute the site survey entirely from the mobile station.

• When using the active mode, conduct the site survey with all variables set to operational values.

Additional Information

Also consider the following oper ating and environmen tal condi tions whe n performi ng a site survey:

• Data rates – Sensitivity and range are inversely proportional to data bit rates. Therefore, the

maximum radio range is a chieved at the lowest workable data rate , and a decr ease in re ceiver
threshold sensitivity occurs as the radio data increases.

• Antenna type and placement – Proper antenna configuration is a critical factor in maximizing

radio range. As a general ru le, range i ncrease s in proporti on to antenn a height .

• Physical environment – Clear or open areas provide better radio range than closed or filled areas.

Also, the less cluttered the work environment, the greater the range.

• Obstructions – A physical obstruction suc h as metal she lving or a steel pi llar can hind er the

performance of wireless devices. Avoid placing these devices in a location where a metal barrier is
between the sending and receiving antennas.

• Building materials – Radi o pen etr at ion is g re atl y i nflue nc ed by t he buildin g m ate ria l us ed in

construction. For exa mple , dr ywal l co nst ruct ion al lows grea ter r ange tha n co ncre te bloc ks, and

Note Refer to the Hardware Installation Guide for your infrastructu re de vice for additio nal information on

factors affecting placement.

Specifying Signal Strength Units

Follow the steps below to specify how signal strength units are displayed on th e site survey screens .

Step 1 Double-click the Aironet Client Utility (ACU) icon on your desktop to open ACU.
Step 2 Click the Preferences icon or select Preferences from the Options drop-down menu. The Aironet Client

Utility Preferences screen appears.
