Introduction
The Nokia C110 Wireless LAN Card and the Nokia C111 Wireless LAN
Card are extended type II PC cards, offering a data transmission rate of up to
11 Mbit/s in a wireless local area network (LAN) environment. The Nokia
C110 features two internal antennas for compact size. The Nokia C111 is
equipped with internal antennas and two external antenna connectors.
The Nokia C110/C111 Wireless LAN Card:
• Complies with the IEEE 802.11b standard.
• Supports data rates of 1, 2, 5.5, and 11 Mbit/s.
• Operates at a frequency of 2.4 GHz using direct sequence spread spectrum
(DSSS) radio technology.
• Supports the Windows® 95, Windows® 98, Windows® 2000, and
Windows NT® 4.0 operating systems. For other supported operating
systems, please check the Nokia Web site at www.nokia.com.
Nokia’s wireless LAN cards enable you to connect wirelessly laptop
computers, hand-held devices, desktop PCs, and other devices with a type II
or III PC card slot to a wired local area network through an access point.
Instead of cables, radio waves are used to transmit and receive data over the
air. With the Nokia C110/C111 you can:
• set up an infrastructure network where wireless stations communicate with
wired and wireless stations through an access point. You can wirelessly
access your company database, e-mail, the Internet, and other network
resources, for example.
• set up an ad hoc network where wireless stations send and receive data
directly with each other. No access point is needed, and as long as the
stations are within range, you can, for example, share and exchange files.
The Nokia C110/C111 comes with an integrated smart card reader. Vital
information, such as security keys and personal network profiles that make
user authentication reliable and moving between networks easy, can be
stored on a smart card.
Wireless LAN
The wireless LAN cards described in this document are approved for use in a
wireless local area network.
The wireless LAN card employs the data transmission capabilities of a
wireless LAN in order to send and receive data, to browse the Internet, and to
establish connections with other computers, for example.
7
Data connections can be made from most locations where your wireless
LAN card operates. However, it is recommended that you move the wireless
LAN card to a location where the strongest possible network signal can be
obtained. When the signal is strong, data transmission is efficient.
The following factors may impair wireless connections:
Noise
Electronic appliances and equipment can cause radio interference. Also in
areas where wireless LAN cards are prevalent, other wireless LAN cards can
impair the wireless connection.
Roaming
As the wireless LAN card user moves from one access point coverage area to
another, the signal strength of the channel drops. As a consequence, the
network may hand the user over to a coverage area and frequency where the
signal is stronger. Due to varying network traffic loads, roaming may also
occur when the user is stationary.
Electrostatic discharge
A discharge of static electricity from a finger or a conductor may cause
erroneous functions in electrical devices. The discharge may result in
unstable software operation. Network connections may become unreliable,
data may be corrupted, and the transmission halted. In this case, end the
existing connection (if any), stop the wireless LAN card and remove it from
the PC card slot. Then re-insert the wireless LAN card into the PC card slot
and try connecting again.
Dead spots and dropouts
Dead spots are areas where radio signals cannot be received. Dropouts occur
when the wireless LAN card user passes through an area where the radio
signal is blocked or reduced by geographical or structural obstructions, such
as concrete walls.
Signal impairment
Distance and obstacles can cause out-of-phase reflected signals that result in
a loss of signal strength.
Low signal strength
Due to either distance or obstacles, the radio signal strength from an access
point may not be strong or stable enough to provide a reliable wireless
connection for communication. Therefore, to ensure the best possible
communication, remember to consider the following points:
•Data connection works best when the wireless LAN card is in a stationary
position.
•Do not place the wireless LAN card on a metal surface.
8
Important!
Warning: Do not use the wireless LAN card when the use of a wireless
device is prohibited or when it may cause interference or danger. Note
that the wireless LAN card may cause similar interference as a cellular
device and must not be used in areas where the use of a cellular device is
prohibited.
Warning: Be careful when moving your computer so that you do not
cause damage to the protruding end of the inserted wireless LAN card.
Warning: In Europe, this equipment is intended to be used in the
following EU Member States: Austria, Belgium, Denmark, Finland,
Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal,
Spain, Sweden, and United Kingdom. This equipment can also be used
in Iceland, Norway, and Switzerland.
Warning: Use the wireless LAN card in the specified countries only.
Using the wireless LAN card in any other country or with an incorrect
country setting is prohibited and may be illegal.
Warning: This equipment operates at 2.4 - 2.4835 GHz. The use of this
equipment is prohibited in France.
Note: Transmitted data is not encrypted by the wireless LAN card by
default. For more information about security in data transmission,
please visit www.nokia.com.
Security
Security issues should always be carefully considered to ensure the secure
transmission of data in both wired and wireless LANs. In current wireless
systems, for example, access points need to authenticate wireless stations to
prevent unauthorised access to the network. Authentication is a service that
confirms the identity of an entity, such as a user or a computer, or confirms
the originality of a transmitted message.
The Nokia C110/C111 supports the Wired Equivalent Privacy (WEP)
protocol to ensure security equivalent to that of a wired local area network.
The WEP protocol utilises the RC4 algorithm with an up to 128-bit secret
key, which encrypts data before it is transmitted over the radio waves. This
provides protection against intruders and unauthorised access to the data.
When the wireless stations in a wireless LAN wish to communicate using
WEP, they must have the same secret key in possession.
The Nokia C110/C111 is equipped with an integrated smart card reader.
Smart cards and smart card readers provide a tool for managing secure user
authentication in a wireless LAN. Smart cards also provide an easy way for
users to carry an authentication device with them. On a smart card users can
store important information, such as security keys and network profiles. The
smart card reader reads the data stored on the computer chip and sends it to
9
the network for processing. The smart card is protected by a PIN code; to
access the contents of the smart card, you need to enter the correct PIN code.
Warning: Keep all miniature smart cards out of small children’s reach.
The WEP protocol and smart card make user authentication and
authorisation reliable and secure, thereby protecting the network from
unauthorised intruders.
Antennas
The Nokia C110/C111 Wireless LAN Card is equipped with two internal
antennas for improved signal quality and coverage area. As with any other
radio transmitting device, do not touch the antenna unnecessarily when the
wireless LAN card is in use. Contact with the antenna affects the quality of
the transmission and may cause the wireless LAN card to operate at a higher
power level than otherwise needed.
Note: Make sure that the antenna is pointing towards the access point
and placed in an open area. Do not cover the antenna.
The Nokia C111 has two antenna connectors for attaching external
antennas for coverage area extension. The Nokia C111 can be used with up
to two external antennas at the same time. Use only the supplied antennas or
an approved external antenna. Unauthorised antennas, modifications, or
attachments could damage the wireless LAN card and may violate
regulations governing radio devices.
Warning: Use only accessories approved by the wireless LAN card
manufacturer for use with this particular wireless LAN card. The use of
any other type of accessories will invalidate any approval or warranty
applying to the wireless LAN card, and may be dangerous.
Caution: When you disconnect the cable of any external antenna, grasp
and pull the plug, not the cable.
Note: For availability of approved accessories, please check with your
dealer.
Caution: In order to comply with FCC RF exposure
requirements for a mobile transmitter, a minimum
separation distance of 20 cm must be maintained
between the antenna and all persons during
transmission.

Getting started
To access and to operate in a wireless LAN with the Nokia C110/C111
Wireless LAN Card, you need to specify a number of network settings. If
wireless stations are to communicate with each other in the wireless LAN,
the stations must share certain settings. You can leave most settings at their
default value, or use the automatic option when applicable, unless, for
example, the system administrator advises you to the contrary.
Note: When you have changed certain settings, your computer may
prompt you to restart it. Restart your computer to enable the new
settings.
Different wireless LANs require different settings. All necessary settings are
configured when you create a network profile. A profile is a collection of
settings needed for connecting to a wireless LAN. With the Nokia C110/
C111 you do not need to remember these settings by heart or configure them
every time you use your wireless LAN card. You can easily switch between
networks, for example, from headquarters to field office, simply by selecting
the appropriate profile. Any of the settings can be changed by editing the
existing profiles. See “Profiles” on page 19 for more information.
Three profiles with pre-defined settings are automatically created during
software installation. Quick Infrastructure and Quick Ad Hoc profiles
enable quick and easy access to a wireless LAN: you need not configure any
network settings. The Quick Infrastructure profile is used for accessing
public access zones or your corporate network. The Quick Ad Hoc profile is
used for setting up a network where wireless stations communicate directly
with each other without access points. When you activate either of these
profiles, a list of available networks appears where you can select the
network which offers the best signal strength and data rate for
communication. The third pre-defined profile, Wired LAN, contains the
original network settings needed for accessing the wired local area network.
See“Using default profiles” on page 14 for more.
Basic settings
The minimum set of parameters to be configured are listed below.
Note: All wireless stations within a wireless LAN must share the basic
settings if the stations are to communicate with each other.
Country
You must always configure the country setting according to the country
where you are currently using your wireless LAN card. Using the Nokia
11
C110/C111 Wireless LAN Card in any other country not specified, or with an
incorrect country setting is prohibited and may be illegal.
The country setting can be configured on the General settings page.
Operating mode
The Nokia C110/C111 enables different types of communication in a
wireless LAN. There are two operating modes to choose from: infrastructure
and ad hoc.
Infrastructure
The infrastructure operating mode allows two kinds of communication:
•Wireless stations communicate with each other through an access point.
•Wireless stations communicate with a wired LAN station through an access
point.
The advantage of the infrastructure operating mode is that you can have
more control over network connections because they pass through an access
point. A wireless station can access the services that are available for a
regular wired LAN by using an access point.
Ad hoc
In the ad hoc operating mode, wireless stations communicate directly with
each other; no access point is required. Simply insert the wireless LAN cards
into the stations, make the necessary configurations, and start
Figure 1 - Infrastructure networking
12
communicating. Ad hoc networking is easy to set up, but communication is
limited to stations that are within range.
Select the desired operating mode when you are creating a new profile with
the Profile Wizard. If you want to change the operating mode later, go to the
Profiles page and click Edit.
Network name
The network name is the name of the wireless LAN to which the card can
connect. It is usually programmed into an access point by a system
administrator. You should ask the system administrator for the network
name.
You can save more than one network name for each profile. If you enter more
than one network name, the names must be separated from each other by a
semicolon, for example: Headquarters;Office4.
Within a network, there may be subnetworks that all have different names,
for example: Office_wlan1, Office_wlan2, Office_wlan3, etc. One profile
can be used to connect the wireless LAN card to all the subnetworks. The
network name may include a special character, a wildcard *, which can be
used as a place holder for one or more letters or numbers. By using the
wildcard, you can specify Office_wlan* as the network name, and the
wireless LAN card can be connected to any of the networks whose name
starts with Office_wlan.
In the ad hoc operating mode, the users themselves give a name to the
network.
Note: The network name can consist of up to 32 alphanumeric
characters. By default, the network name is case-sensitive. To change
this property, go to the General settings page and select the Advanced
tab. There you can clear the Case-sensitive network names check box.
If you want to change the network name later, go to the Profiles page and
click Edit.
Figure 2 - Ad hoc networking
13
Channel
The Nokia C110/C111 operates in a frequency band of 2.4 GHz. You need to
specify a radio frequency channel on which the wireless LAN card is used.
The selection of available channels may vary from country to country, as
certain countries have a limited number of channels that can be used.
You can select the Automatic channel selection option when you are creating
a new profile with the Profile Wizard: you need not specify a channel, and
you are automatically allocated an available channel. You can, however,
also select the correct channel yourself. In that case, make sure that the
wireless LAN card and the access point are using the same channel.
If you want to change the channel setting, go to the Profiles page and click
Edit.
Connecting to a network
The Nokia C110/C111 Wireless LAN Card connects your computer
automatically to the access point and network that offer the best quality for
communications. If you move the computer to another location within the
network and out of range of the access point, the roaming functionality will
automatically connect your computer to another access point that belongs to
the same network. As long as you remain within range of access points that
belong to the same network, your computer will stay connected to the
network.
Once you have installed the software for the Nokia C110/C111, you can
connect to a wireless LAN.
1Insert the wireless LAN card firmly into the PC card slot of the computer.
See Figure 3.
Figure 3 - Inserting the card

the PC card slot, but there is a gap between the protruding extension
box and the computer. Do not use excess force when inserting the card.
2Power on your computer.
3If you are using a smart card, enter the PIN code and click OK.
4Open the program by right-clicking the Nokia C110/C111 icon on the
taskbar. A short-cut menu opens. Click Manager window or Profiles.
5The Profiles page opens. Under Profile selection, select the profile you
want to use with the wireless LAN in question. Click Apply. You may need
to restart your computer. If you are about to connect to a new network and
therefore need to create a new profile, or if you need to modify an existing
profile, see “Creating new profiles” on page 20, or “Editing profiles” on
page 22.
Setting up and joining an ad hoc network
Ad hoc networks allow wireless stations to communicate directly with each
other without any access points. The stations can, for instance, share folders.
One user creates the ad hoc network and other users then join the network.
Only those stations that have the correct password can join the network.
To start an ad hoc network:
1On the Profiles page, select the Quck Ad Hoc profile and click Apply.
2Give the ad hoc network a name and a password. Click Start.
To join an ad hoc network:
1On the Profiles page, select the Quck Ad Hoc profile and click Apply.
2Select the network you want to join and click Join.
Note: When you select a profile for ad hoc networking, the system will
ask you to restart your computer if your network settings need to be
changed. Restart your computer and then either start a network or
select the network you want to join.
Tip: Create your own profile for ad hoc networking with the Profile
Wizard if you use the ad hoc operating mode frequently. This saves you
from having to start a network each time and allows quicker access. See
“Creating new profiles” on page 20 for more.
Using default profiles
Three default profiles are created during the installation: Quick
Infrastructure, Quick Ad Hoc, and Wired LAN profiles. With these profiles
you can easily and quickly establish a network connection: you get a list of
available networks and can join one without having to change the network
settings manually. The Wired LAN profile contains the original network
settings needed for accessing the wired local area network. Note that these
15
profiles cannot be edited, deleted, or exported. The Wired LAN profile,
however, can be updated to comply with the current wired LAN settings.
1On the Profiles page, select the appropriate default profile, and click
Apply. If your network settings need to be changed, the system will ask you
to restart your computer. In that case, restart the computer.
2A dialog box with a list of accessible networks opens. Select a desired
network and click OK. The wireless LAN card will join the network.

menu.
The Manager window consists of several pages: Profiles, Status, General
settings, Diagnostics, and Update. The administrator page is used by system
administrators. You can view the different pages by clicking the icons on the
left icon bar.
Profiles
For the Nokia C110/C111 to operate in wireless local area networks, you
need to configure certain settings for each network. For example, when you
use the card in your office LAN, you need different settings compared to the
LAN at an airport you are visiting. On the Profiles page you can configure the
necessary settings and create network profiles for specific wireless LAN
environments. A profile is a group of wireless LAN specific and Windows
networking settings that you need for accessing wireless LANs. Profiles
enable easy transfer from one network to another without having to
remember all the different settings. On the Profiles page you can also modify
Figure 5 - Manager window
20
existing profiles and create new profiles. Profiles are stored to a hard disk or
a smart card.
Selecting profiles
You need to select a network profile suitable for the wireless LAN in which
you want your wireless LAN card to operate.When you insert the wireless
LAN card into your computer, the card selects the profile last used as a
default profile. If, however, you want to use another profile, you can either
select it from the list of existing profiles or create a new one.
In the Profile selection area, there is a list of profiles from which you can
select a profile with all necessary settings for a particular wireless LAN. If
you have connceted to a network previously, you can simply select the profile
for that network and then click the Apply button. The profile which is
currently active is indicated with a green check mark, while a profile which
has been selected but has not yet been activated, has a frame around it. A
profile which is used from a smart card is indicated with a small smart card
symbol. The name of the active profile is displayed in the Operating
information area. See Figure 5 on page 19.
Note: When you select a different profile, you may be prompted to
restart your computer.
Note: You may need to change the proxy settings when you change
profiles.
Creating new profiles
By creating different profiles for different wireless LANs, you can easily
switch from one wireless LAN to another without having to memorise the
network settings.
1To create a new profile, click New. The Profile Wizard opens. This wizard
will guide you through creating a new profile. To continue, click Next.
Note: Most settings can be left at their default value, as in most cases
these settings are sufficient to provide good quality communications.
However, there are situations when you may need to change the default
settings.
2Type a name for the new profile. You can select the name yourself and it
can consist of up to 30 alphanumeric characters. In the text box you can
enter information which can help you in identifying the different profiles.
This information can contain up to 108 characters. Click Next.
Tip: When you create new profiles, make the name of the new profile as
descriptive as possible. This enables a quick selection between different
profiles. You can also add further details about the profile, for example
the name or address of the place where the wireless LAN is located.

been inserted into the PC card slot of the
computer.
Connection weak indicates that something is
either obstructing the connection (a concrete
wall, for example) or the computer has moved too
far away from the access point.
Authorization failed indicates that you have
possibly used a wrong WEP key, or that you have
no access rights for the network.
OPERATING MODE Type of network communication in use.
In the infrastructure mode, computers can
communicate with each other and with wired
LAN stations through an access point. In the ad
hoc mode, computers can send and receive data
directly with each other. No access point is
needed.

LAN card is operating.
DATA RATE Speed at which data is being transferred. Possible
rates are 1, 2, 5.5, and 11 Mbit/s
MAC ADDRESS Unique hardware address of the wireless LAN
card.
SIGNAL STRENGTH Indicates the quality of the radio connection
between the computer and the access point, or, in
the ad hoc mode, between two computers.
26
Smart Card tab
The Smart card information area shows information on the smart card
which is being used by the wireless LAN card: the name and status of the
smart card, when the smart card was created and by whom, and an optional
description of the smart card.
If you temporarily want to lock the smart card in order to deny access to it,
click Lock. Those profiles which are used from the smart card will not be
shown in the list of available profiles on the Profiles page. To access the smart
card again, click Unlock, type your PIN code and click OK.
Your smart card has a default PIN code 0000. For security reasons it is
important that you change the PIN code. To change the PIN code, click

Keep the new code secret and in a safe place. If you enter an incorrect PIN
code three times in a row, the smart card will be blocked and cannot be used.
To change a disabled PIN code, you need a PUK (PIN Unblocking Key) code.
The PUK is unique for each smart card and it cannot be changed. You can
find the PUK code for your smart card from the sales package of the smart
card.
Access Points/Stations tab
In the infrastructure operating mode, the Access points in range area shows
which access points are currently in range and available. As the wireless LAN
card user moves from one access point coverage area to another, the signal
strength of the channel drops. Therefore the network may hand the user over
to a coverage area and frequency where the signal is stronger.
In the ad hoc operating mode, the names of the other computers connceted to
the ad hoc network are displayed. Note that only the names of those
computers which are using Nokia’s wireless LAN card are shown. By
double-clicking the entries, you can access those folders which are shared.

General settings
On the General settings page you can set properties which are common for all
profiles. These settings will remain unchanged even when you switch to
using another profile.
General tab
Country selection
You must always configure the country setting according to the country
where you are currently using your wireless LAN card. Select the correct
country from the list of countries and click Apply.
Warning: Use only the country setting appropriate for the area where
the wireless LAN card is used at the present time. Using the wireless
LAN card in any other country not specified, or with an incorrect
country setting is prohibited and may be illegal.
The Nokia C110/C111 operates in the license-free frequency band of 2.4
GHz, but local regulations may limit the use of radio equipment. Therefore,
the selection of available channels varies according to the country where the
wireless LAN card is used.
Power saving
Since a wireless LAN card has no direct wire connection of its own, it uses
power from the host computer. The Nokia C110/C111 is equipped with a
power saving option, which allows you to control the power consumption of
your computer: you can prolong the life of the battery when needed.
If you select the Enable power saving check box, the wireless LAN card will
be fully powered up only when sending or receiving data. The card wakes up
from the power saving mode at regular intervals to check if there is any data
for it at an access point, and wakes up immeditaley when there is any
outgoing data.
28
Note: The speed of communication drops slightly when the power
saving option is used.
Monitor window
By default, the Monitor window opens in the middle of the display area of
your computer. If you want to move the Monitor window to a different place
on the screen and want it to be displayed on that position the next time you
open it, select the Remember Monitor window position check box. The next
time you open the Monitor window, it will be in the same place where you
had moved it.
Select Always show Monitor window on top if you want the Monitor
window to remain visible even when you have other applications open.
When you insert the Nokia C110/C111 Wireless LAN Card into your
computer, a small icon appears on the taskbar. By right-clicking this icon a
shortcut menu opens, and you can access either the Monitor window or the
Manager window. If, however, you want the Monitor window to open
automatically each time the card is inserted, you can select the Open Monitor
window automatically option.
If you select Always show icon in taskbar, the small Nokia C110/C111 icon
on the taskbar will be displayed even when the card has not been inserted.
For the changes to take effect, click the Apply button. If you have made
changes to the settings but then wish to restore the previous settings, click
Restore.
Personal Keys tab
Personal WEP keys are used for authenticating the user in a network.
Personal keys are not network specific, and are therefore not saved together
with profiles. They are, however, saved in a file independently from profiles.
The system administrator can store personal WEP keys on a smart card.
Personal keys can be used only with the infrastructure operating mode. Ad
hoc networks use shared keys only. See “WEP security” on page 33 for more.
There are two types of personal keys, and the difference between the keys is
the type of information which is used for authenticating the user:
To create a new personal key:
1Click New.
2Give the personal key a name. You can also add a further description of the
key, such as the name of the network where the key is used.
USER-SPECIFIC Uses an identifier which the users can create
themselves.
STATION-SPECIFIC Uses the MAC address of the wireless LAN card for
identifying the user.
29
3Select the type of key you want to create: user-specific or station-specific. If
you choose a station-specific key, the MAC address of the wireless LAN
card will be used as an identifier. If you choose a user-specific key, you can
choose the identifier yourself.
4Select the appropriate key length. Supported key lengths are 40, 56, 64, and
128 bits. Remember that the more bits there are in the key, the higher the
level of security. Click Generate. The system generates your personal key.
5Click OK.
Similarly, you can edit existing keys. You can also delete keys you do not
need any more. Instead of creating a personal key yourself, you can import
from a folder a key created by a system administrator. You can export and
save personal keys in folders. The system administrator can also store
personal keys on smart cards.
Note that on the Personal Key tab you cannot select a personal WEP key to be
used. To select a personal key to be used with a certain profile:
1Go to the Profiles page, select the profile you want to modify, click Edit,
and select the Security tab.
2Select Use WEP security, then select Use personal WEP key. Click Select.
3A list of personal WEP keys is displayed. Select a personal key from the list
and click OK.
4Click OK to close the Edit Profile dialog box.
Advanced tab
When you create profiles, you are asked to specify whether you want the
DHCP server to allocate an IP address for the wireless LAN card, and
whether you want your computer to log on to a domain. By default, these
settings are managed automatically as defined in each profile.
When the Manage TCP/IP properties together with profiles check box is
cleared, profiles will be activated without TCP/IP settings. You can change
the settings manually in the Control Panel.
Profiles will be activated without domain settings if the Manage domain
settings together with profiles check box is cleared. You can change the
settings manually in the Control Panel.
Note: Both of these check boxes must be selected if you want the system
to be able to log you on to a domain or allocate IP addresses.
By default, the network name is case-sensitive. To change this property, clear
the Case-sensitive network names check box.
For the changes to take effect, click the Apply button. If you have made
changes to the settings but have not saved them yet by clicking Apply, and if
you then want to restore the original settings, click Restore.

Diagnostics
On the Diagnostics page you can run a series of fault diagnosis tests to ensure
that the Nokia C110/C111 Wireless LAN Card and the software are
operating correctly. If you encounter problems in accessing the wireless
LAN, for example, the tests can help to identify the source of the problem.
The tests check that the software files have not been modified, that the
settings configured both on the Profiles and General settings pages are valid
and do not conflict, that the wireless LAN drivers have been installed
correctly, and that the card does not have any hardware problems. If the card
does not pass a test, you are given advice on how to proceed.
To start the fault diagnosis test, click Start. You can stop the test at any time
by clicking Stop. The test results are displayed in the Advice area.
•The Repair button is activated if the software finds a fault which can be
corrected automatically by the software.
•The Help button opens the troubleshooting section of the online help,
where you can find information on how to solve possible problems.
•The Support button opens the online help where you get information on
how to contact Nokia’s technical support.
You are advised to run the diagnosis tests in a situation when the Monitor
window, for example, reports a failure with the network connection, or
when you have problems in accessing a network. A number of possible
problem situations are covered in this guide under “Troubleshooting” on
page 38.
Update
You can download the latest software version of the Nokia C110/C111
Wireless LAN Card from Nokia’s customer support Web site. In order to be
able to update your software, you first have to register to Nokia’s customer
database.
Registering to the customer database
You can register to Nokia’s customer database electronically, simply by
clicking the Register button. Your Web browser opens and you are taken
directly to the Nokia Web site where you get further information on
registration and where you find the registration form. You are asked to select
a user name and a password. You need them when logging into the Web site
where the updated software can be downloaded. Notice that you will not be
able to download the software updates immediately after registering, as it
takes a while for your user name and password to become valid.
31
Tip: Because it takes a while for your user account information to
become valid, it is recommended that you register at your earliest
convenience. This way you can get the software update as soon as you
actually need it, instead of having to wait for the user account
information to become valid.
Updating software
Once you have registered to Nokia’s customer database and your user name
and password are valid, you are entitled to download the latest software
version for the Nokia C110/C111 from Nokia’s Web site .
Click the Update button. Install the updated software version for your
wireless LAN card. The installation is carried out in the same manner as the
original installation from the CD-ROM.
Note: All the existing settings which you have configured on the Profiles
and General settings pages - including your personal profiles - will
remain unchanged even when the software has been updated.
Note: Make sure that your computer has enough battery power before
you start to download the updated software.
Administrator
The Administrator page is meant for system administrators and is not
installed as part of the typical installation procedure. On the Administrator
page the system administrator can save important data on a smart card and
can create installation disks, which then can be distributed to end users
within a corporation, offering quick access to the networked resources.
Creating smart cards
The system administrator can store important information such as personal
WEP keys and network profiles on a smart card. The administrator can then
give users smart cards which contain the necessary network settings and
encryption keys for quick network access. The user inserts the smart card
into the Nokia C110/C111, inserts the wireless LAN card into a computer,
and is then ready to access the wireless LAN.
Nokia’s integrated smart card reader provides a highly reliable and efficient
tool for managing user identities and user authentication in the wireless
network. A smart card provides a tangible, reliable way to distribute
network authentication keys to mobile users. WEP encryption together with
the smart card functionality ensure a high level of security.
To store data on a smart card:
32
1Slide the smart card into the smart card slot. Make sure that the metal
contacts of the smart card are facing down and that the bevelled corner is
on the right. See Figure 6 on page 36.
2Insert the wireless LAN card in your computer and start the Nokia C110/
C111 program. Go to the Administrator page. In the Smart card area click
Add/Remove.
3The Smart Card dialog box opens. Select the items on the left to be copied
to the smart card. Click the arrow button pointing to the right. If you want
to remove items from the smart card, select the desired items on the right
and click the arrow button pointing to the left.
4You can type additional information about the smart card in the Smart
card description text box.
5Click OK to save the selected items to the smart card.
Note: Profiles are copied to a smart card when the Keep data after
storing on smart card check box is selected. If this check box is cleared,
the selected profiles will be removed - instead of being copied - from the
system to a smart card.
If you want to empty the contents of a smart card, click Erase All. Note that
all items on a smart card will be removed. If you want the program to re-read
the contents of a smart card, click Reload.
Creating installation disks
The system administrator can create INF based installation disks where
selected settings can be copied to a disk.
The installation disk can be used for distributing profiles. All the desired
settings and profiles can be copied to the installation disk, which then offers
an end-user quick access to a wireless LAN. The end user does not have to
configure the settings in order to be able to connect to a network.
To generate an installation disk:
1On the Administrator page, in the Installation disk area, click Create.
2The Installation disk dialog box opens. The Profiles available list contains
the names of all the profiles found in the system registry. Select the profile
you want to save on the installation disk and click Add.
Note: General settings are automatically copied to a disk, they do not
have to be selected separately like profiles.
3The name of the selected profile is added to the list on the right. If you want
to remove a profile from the list, select it and click Remove. To start
creating an installation list with the selected profiles, click OK.
The user inserts the Nokia C110/C111 into a computer, then inserts the
installation disk into the disk drive, and the installation is carried out
without the user having to configure any settings. When the installation has
been completed, the user is ready to access the wireless LAN.
33
Security options
WEP security
To provide secure communication over the wireless LAN, the Nokia C110/
C111 offers the WEP (Wired Equivalent Privacy) security feature. WEP uses
the RC4 algorithm with an up to 128-bit key. The algorithm provides for
security via two methods: authentication and encryption. Authentication is
the means by which one wireless station is verified to have authorisation to
communicate with a second station in a given coverage area. In the
infrastructure mode, authentication is established between an access point
and each wireless station. If a wireless station receives a packet which has not
been scrambled with a correct key, the packet is discarded. Encrypted
messages can be opened by other wireless LAN cards only if they all use the
same encryption key.
The WEP feature offers a security level comparable to that of wired
networks. The level of security is dependent on the length of the key: the
more bits in the key, the longer it takes to decrypt the information sent and
the higher the level of security. There are two types of WEP keys: shared keys
and personal keys.
Shared keys
Shared WEP keys are shared by all wireless stations using the network or
subnetwork; only stations which have the correct key can receive and
decrypt data. Shared keys are usually created by system administrators, who
distribute them to users. In the ad hoc operating mode, one of the users can
create a shared key and then distribute it to the other users.
Shared keys are network specific, and each network can have up to 4 shared
keys. The name of a shared key is the same as the name of the network.
Because the shared WEP keys are network specific and user-independent,
they can be saved in a file together with profiles. Users can import from a file
or a smart card profiles and shared keys which have been created by their
system administrator.
Shared keys can be used as the only form of WEP security, or together with a
personal key.
Personal keys
Personal keys are used for providing additional security for wireless
connections. There are two types of personal keys, and the difference
between the keys is the type of information which is used for authenticating
the user:
USER-SPECIFIC Uses an identifier which the users can create
themselves.
34
Unlike shared keys, personal keys are not network specific, and therefore
cannot be saved together with profiles. They can, however, be separately
saved in a file.
Note: Personal keys can be used only with the infrastructure operating
mode. Ad hoc networks use shared keys only.
Creating and editing shared keys
Shared keys are usually created by a system administrator. In the ad hoc
operating mode, the person who is starting the network has to generate a
shared key and then distribute it to others.
1On the Profiles page, select the profile you want to modify, click Edit.
2Select the Security tab, then select Use WEP security. If you do not select
this check box, WEP encrypted communication will be ignored. Click
New if you want to generate a new shared key or Edit if you want to edit an
existing one.
3The Edit Shared Key dialog box opens. Type the name of the network
where the key will be used, or select one from the list. The name of the
network and the shared key must be the same.
For each wireless LAN network you may specify four shared keys. In the
Use as list, select a slot for the key.
Select the appropriate key length. Supported key lengths are 40, 56, 64, and
128s. The more bits in the key, the higher the level of security. Click
Generate. The system generates your shared key.
4Click OK.
Importing and exporting shared keys
You can import shared WEP keys from a file or from a smart card, and
export a shared key to a file. The system administrator can save shared WEP
keys on a smart card.
1On the Profiles page, select the profile you want to modify, click Edit, and
select the Security tab.
2Select Use WEP security, and click Import or Export.
3Select the source from which you want to import or the destination to
which you want to export the shared key. You can select a WEP key from
a smart card only if the profile in question is also used from a smart card.
Creating and editing personal keys
Personal keys can be used only with the infrastructure operating mode.
STATION-SPECIFIC Uses the MAC address of the wireless LAN card for
identifying the user.
35
Note: You also have to set the personal key to the access point in order
to be able to communicate with it.
1On the General settings page, select the Personal keys tab. Click New if
you want to generate a new personal key or Edit if you want to edit an
existing one.
2Give the personal key a name. You can also add a further description of the
key, for example the name of the network where the key is used.
3Select the type of key you want to create: station-specific or user-specific. If
you choose a station-specific key, the MAC address of the wireless LAN
card will be used as an identifier. If you select a user-specific key, you need
to type in an identifier yourself.
4Select the appropriate key length. Supported key lengths are 40, 56, 64, and
128 bits. Remember that the more bits there are in the key, the higher the
level of security. Click Generate. The system generates your personal key.
5Click OK.
Importing and exporting personal keys
You can import personal WEP keys from a file and save them to a file. The
system administrator can import personal WEP keys from a smart card and
export them to a smart card.
1On the General settings page, select the Personal keys tab. Select the key
you want to import or export and click Import or Export accordingly.
2If you are importing a key, select the source from which you want to import
it and click Open. If you are exporting a personal key, select the
destination to which you want to save the key. Click Save.
Selecting a personal key
1Go to the Profiles page, select the profile you want to modify, click Edit,
and select the Security tab.
2Select Use WEP security, then select Use personal WEP key. Click Select.
3A list of personal WEP keys is displayed. Select a personal key from the list
and click OK.
4Click OK to close the Edit Profile dialog box.
Smart cards
A smart card is a miniature SIM-card sized plastic card with an embedded
computer chip. Smart cards provide a means of storing vital information
such as security keys or network profiles. Smart cards also provide an easy
way for users to carry data with them. A smart card reader is needed to read
the electronic data from the card: the Nokia C110/C111 is equipped with an
integrated smart card reader.
36
The smart card is protected by a PIN code, which provides an additional tool
for managing secure user authentication in a wireless LAN. Only a person
who knows the PIN code can access the information stored on the smart
card. Your smart card has a default PIN code 0000. For security reasons it is
important that you change the PIN code. Keep the new code secret and in a
safe place. If you enter an incorrect PIN code three times in a row, the smart
card will be blocked and cannot be used. To change a disabled PIN code you
need a PUK (PIN Unblocking Key) code. The PUK code is unique for each
smart card and cannot be changed. You can find the PUK code from the sales
package of your smart card.
Caution: The smart card and its contacts can be damaged by scratches or
bending, so be careful when you handle, insert, or remove the card.
The smart card which you receive from your system administrator, for
example, can contain predefined network profiles which enable you to

Troubleshooting
If you encounter problems when installing and/or using the Nokia C110/
C111 Wireless LAN Card, this chapter will assist you in finding out where
the problem may lie. The chapter has been divided into sub-categories
according to the type of problem.
Tip: When troubleshooting the wireless LAN card, a good starting point
is to go through the following questions:
1Was the installation successful?
2Is the wireless LAN card connected to an access point? You can check the
status of the network connection in the Monitor window.
3Are the network settings, such as TCP/IP properties, correct? Check with
your system administrator if necessary.
4Are the wireless LAN settings (network name, operating mode, etc.)
correct?
5Are there any IRQ or other resource conflicts?
Installation
The installation program is interrupted.
Make sure you have enough power on your computer.
Make sure you have enough free disk space on your computer.
Check that you have closed all Windows programs before starting the
installation, and that you have not inserted the wireless LAN card into your
computer until prompted to do so in the installation program.
The wireless LAN card cannot be inserted into the PC card slot.
Check that the wireless LAN card is turned the right side up.
Check the PC card slot for any problems.
After inserting the wireless LAN card, it takes a while before the computer
responds.
It is true that there might be a pause while the driver initialises the wireless
LAN card. This is quite normal. Please wait until the next message box
appears and tells you what to do. This should not take more than a few
minutes.
39
Installation to a network drive fails.
You cannot install the Nokia C110/C111 Wireless LAN Card software onto
a network drive. The software must always be installed on a local hard drive.
Network
The wireless LAN card seems to be working, but the network connection does not
work.
Run the fault diagnosis tests on the Diagnosis page. If all tests are passed
successfully, make sure that the network settings are correct. Ask your
system administrator for advice.
If you have defined different profiles for different networks, you should also
check that you have chosen the correct profile.
You can use winipcfg in Windows 95/98 and ipconfig in Windows NT 4.0 to
check that you have a correct IP address.
Network Neighborhood does not show any computers except the host itself.
Check that you have version 2.0 of Microsoft Winsock. If not, download it
from the Microsoft Web site and run the installation program. In Windows
NT it can take up to a couple of minutes for the computer to detect the rest of
the network.
In Windows 95/98, Network Neighborhood does not show my computer name at
all. Other computers cannot see my computer name in Network Neighborhood
either.
Open the Network dialog box (click Start, Settings, Control Panel,
Network) and click the File and Print Sharing button. Make sure that the I
want to be able to give others access to my files check box is selected. Other
users should now be able to see your computer in Network Neighborhood. If
you share folders on your computer, other users can see them too.
In Windows 95, I cannot browse Network Neighborhood in the ad hoc operating
mode.
Check that the Browse Master in Network Properties/File and Printer
Sharing for Microsoft Networks is not disabled (should be enabled/
automatic). Updating Network Neighborhood may take a while.
I cannot access the Internet.
Check that you use a routing protocol such as TCP/IP.
Make sure that the proxy settings in the Web browser are correct.
Also make sure that there is a connection from your network to the Internet.
40
Wireless LAN
The wireless LAN card is detected by the PC card controller, but the user interface
is not displayed and there is no network connection.
Check that the Nokia C110/C111 Wireless LAN Card software is properly
installed by running the fault diagnosis tests. If necessary, uninstall the
software and then reinstall it.
The wireless LAN card cannot connect to an access point.
Check that the computer is within the coverage area of the access point. It
must not be too far away or too close to the access point.
Make sure that the access point is powered on and connected to the wireless
LAN.
Ensure that you have entered the correct network name. The access point
and the wireless LAN card must have the same network name.
Check that you have access rights to the access point, and that the access
point is connected to a network to which you have access rights.
The ad hoc operating mode does not work.
Make sure that all computers are on the same channel and have the same
network name.
Make sure that all computers use the same network protocol, such as TCP/
IP.
Make sure that you have given the right password if you are using WEP keys.
The wireless LAN card works but there is no network connection or it is very poor.
Check that the external antenna is properly connected and that no part of the
cable is broken.
The wireless LAN card is working but the capacity is decreasing.
There might be interference from an outside source. Typical sources of
electromagnetic interference at this frequency level are, for example,
microwave ovens, access control systems, and cordless telephone systems.
The Quick Ad hoc profile does not work with the peer-to-peer mode of the Nokia
C020/C021.
Quick Ad hoc is not compatible with peer-to-peer networking. Wireless
stations can communicate, but TCP/IP addresses cannot be set
automatically. Create a new ad hoc network profile with the Profile Wizard
and set the TCP/IP address manually.
41
Resources
The wireless LAN card does not work and this is probably caused by another device
installed.
Check that the wireless LAN card is not trying to use an I/O, IRQ, or memory
address used by another device in your computer.
To check the status of resources:
Hardware
I am not sure if the wireless LAN card is working.
Check in the Monitor window that the wireless LAN card is working. You
can also check the Status page for the status of the connection.
There are no resource conflicts, but the wireless LAN card still does not work.
Check that the operating environment does not cause damage or interference
to the wireless LAN card. Detailed information on the operating
environment can be found in the chapter “Important safety information” on
page 44.
Check that the wireless LAN card is properly inserted.
Run fault diagnosis tests on Diagnostics page.
You can try to determine whether the problem lies with the computer or the
wireless LAN card by using the card in another available PC card slot, by
installing the card in another computer, or by using another wireless LAN
card in the first computer.
The wireless LAN card does not work in another PC card slot, but works in another
computer.
Try to insert another PC card in the slot to determine if there is a
compatibility problem between the Nokia C110/C111 Wireless LAN Card
and the PC card slot, or if there is a general fault with the slot.
The smart card is not detected by the wireless LAN card.
Make sure you have the right type of smart card.

Important safety information
Traffic safety
Do not use the wireless LAN card while driving a vehicle. If using the wireless
LAN card, park the vehicle first. Do not place the wireless LAN card on the
passenger seat or where it can break loose in a collision or sudden stop.
Remember: road safety always comes first!
Operating environment
Remember to follow any special regulations in force in any area and always
power off your wireless LAN card whenever it is forbidden to use it, or when
it may cause interference or danger. Note that the wireless LAN card may
cause similar interference as a cellular terminal and must not be used in areas
where the use of a cellular terminal is prohibited.
When connecting the wireless LAN card or any accessory to another device,
read its user's guide for detailed safety instructions. Do not connect
incompatible products.
As with other mobile radio transmitting equipment, users are advised that
for the satisfactory operation of the equipment and for the safety of
personnel, it is recommended that the wireless LAN card should only be used
in the normal operating position.
Electronic devices
Most modern electronic equipment is shielded from radio frequency (RF)
signals. However, certain electronic equipment may not be shielded against
the RF signals from your wireless LAN card.
Pacemakers
Pacemaker manufacturers recommend that a minimum separation of 20 cm
(6 inches) be maintained between a wireless LAN card and a pacemaker to
avoid potential interference with the pacemaker. These recommendations
are consistent with the independent research by and recommendations of
Wireless Technology Research. Persons with pacemakers should always
keep the wireless LAN card more than 20 cm (6 inches) from their pacemaker
when the wireless LAN card is powered on. If you have any reason to suspect
that interference is taking place, power off your wireless LAN card
immediately.
Hearing aids
Some digital wireless devices may interfere with some hearing aids. In the
event of such interference, you may want to consult your service provider.
45
Other medical devices
Operation of any radio transmitting equipment, including wireless LAN
cards, can cause interference. Ask for the staff's permission before using your
wireless LAN card near medical equipment. Power off your wireless LAN
card in health care facilities when any regulations posted in these areas
instruct you to do so.
Vehicles
RF signals may affect improperly installed or inadequately shielded
electronic systems in motor vehicles (e.g. electronic fuel injection systems,
electronic anti-skid (anti-lock) braking systems, electronic speed control
systems, air bag systems). Check with the manufacturer or its representative
regarding your vehicle. You should also consult the manufacturer of any
equipment that has been added to your vehicle.
Do not store or carry flammable liquids, gases, or explosive materials in the
same compartment as the wireless LAN card, its parts, or accessories.
For vehicles equipped with an air bag, remember that an air bag inflates with
great force. Do not place objects in the area over the air bag or in the air bag
deployment area. If the in-vehicle wireless LAN card is improperly placed
and the air bag inflates, serious injury could result.
Posted facilities
Power off your wireless LAN card in any facility where posted notices so
require.
Potentially explosive atmospheres
Power off your wireless LAN card when located in any area with a
potentially explosive atmosphere and obey all signs and instructions. Sparks
in such areas could cause an explosion or fire resulting in bodily injury or
even death.
Users are advised to power off the wireless LAN card when at a refuelling
point (service station). Users are reminded of the need to observe restrictions
on the use of radio equipment in fuel depots (fuel storage and distribution
areas), chemical plants, or where blasting operations are in progress.
Areas with a potentially explosive atmosphere are often but not always
clearly marked. These include the area below deck on boats; chemical
transfer or storage facilities; vehicles using liquefied petroleum gas (such as
propane or butane); areas where the air contains chemicals or particles, such
as grain, dust, or metal powders; and any other area where you would
normally be advised to turn off your vehicle engine.
Wireless devices can cause interference. Ask for the staff's permission before
using your wireless LAN card in an aircraft.
Failure to observe these instructions may be illegal and lead to legal action.

C110/C111. With this configuration option users can set up a wireless
network where wireless stations can send and receive data directly with each
other without access points. This type of network is sometimes called peer-
to-peer network.
Bandwidth
Size (in Hertz) of the operating or transmission channel of a system that a
signal transmission occupies.
Beaconing
Process in which short messages containing the network name are sent by
wireless stations or access points and broadcast ten times a second. A
wireless station listens for these messages after powering up to either confirm
it is on the correct channel or to move to another frequency channel if no
messages are received or if the network name does not match.
Channel
A specified frequency band for the transmission and reception of signals.
Coverage area
Geographical area within which service from a radio communications
facility can be received.
DHCP
