Introduction
1.1
What is a Wireless LAN?
The following sections describe the functionality of wireless networks
in general. The functions supported by your device are listed in the
table ’What can your LANCOM 54 Wireless do?’ →page 9.
A Wireless LAN connects single terminals (e.g. PCs or notebooks) to a local
network (also LAN – Local Area Network). In contrast to a conventional LAN,
communication takes place via radio links rather than via network cables. This
is the reason why a Wireless LAN is also called a Wireless Local Area Network
(WLAN).
All functions of a cable-bound network are also available in a Wireless LAN:
access to files, servers, printers etc. is as possible as the connection of individ-
ual stations to an internal mail system or to the Internet access.
The advantages of Wireless LANs are obvious: notebooks and PCs can be set
up just where they are needed. Due to Wireless LANs, problems with missing
connections or structural alterations belong to the past.
1.1.1
Which hardware to use?
Each station of the Wireless LAN needs access to the Wireless LAN in the form
of a wireless interface. Devices which have no built-in wireless interface can
be upgraded with a supplement card or an adapter.
LANCOM Systems offers wireless adapters by its AirLancer product
line. An AirLancer wireless adapter enables a device (e.g. PC or note-
book) for access to the Wireless LAN.
1.1.2
Operation modes of Wireless LANs and base stations
Wireless LAN technology and base stations in Wireless LANs are used in the
following operation modes:
Simple direct connections between terminals without base station (ad-
hoc mode)
Larger Wireless LANs, connection to LANs with one or more base stations
(infrastructure network)

Meanings of the LEDs
In the following sections we will use different terms to describe the behaviour
of the LEDs:
Blinking means, that the LED is switched on or off at regular intervals in
the respective indicated colour.
Flashing means, that the LED lights up very briefly in the respective col-
our and stay then clearly longer (approximately 10x longer) switched off.
Inverse flashing means the opposite. The LED lights permanently in the
respective colour and is only briefly interrupted.

Flickering means, that the LED is switched on and off in irregular inter-
vals.
Power
This LED indicates that the device is operational. After the device has been
switched on, it will flash green for the duration of the self-test. After the self-
test, either an error is output by a flashing red light code or the device starts
and the LED remains lit green.
The power LED flashes red/green in alternation until a configuration
password has been specified. Without a configuration password, the
configuration data of the LANCOM is insecure. Under normal circum-
stances, you would assign a configuration password during the basic
configuration (instructions in the following chapter).

Time or connect-charge reached
Flashing Power LED but no connection?
There is no need to worry, if the Power LED of a LANCOM 54 Wireless
base station blinks red and you can no longer connect to the WAN.
This indicates that a preset time or connect-charge limit has been
reached. There are three methods available for unlocking:
Reset time limit.
Increase the limit that has been reached.
Completely deactivate the lock that has been triggered (set limit to '0').
If a time limit has been reached, you will be notified in LANmonitor. To reset the connect
charge protection, select Reset Charge and Time Limits in the context menu (right mouse
click). You can configure the connect charge settings in LANconfig under Management
Costs (you will only be able to access this configuration if ’Complete configuration display’
is selected under View Options… ).
You will find connect charge protection reset in WEBconfig and all parameters under Expert

Power-over-Ethernet – elegant power supply through the LAN wiring
LANCOM 54 Wireless base stations are prepared for the PoE power supply (Power-over-
Ethernet), corresponding to the 802.3af standard. PoE-enabled network devices can be com-
fortably supplied with power feeding through the LAN wiring. A separate external power sup-
ply for each base station is unnecessary, which reduces the installation complexity
considerably.
The power feeding into the LAN happens at a central position, either via a PoE power injector,
or via a so-called powerhub/powerswitch. For the LAN wiring is to note that all 8 wires must
be available by the cabling. PoE feeds the power over those four wires, which are normally
not used for data transfer.
The PoE supply works only in such network segments, in which exclusively PoE-capable
devices are operating. The protection of
network devices without PoE support is
guaranteed by an intelligent mechanism,
that tests the network segment for
devices without PoE support before start-
ing the PoE power feeding. The power is
only switched onto the segment, if no
devices without PoE support were
detected.
In a PoE installation use exclusively devices which correspond to the 802.3af
standard! For damages caused by inadmissible devices no warranty may be
claimed.

Wireless, protected by an IP50 sealing cap.
10/100Base-Tx for connection to the LAN. Supported are 10-Mbit or 100-
Mbit connections. The data transfer speed is recognized automatically
(autosensing).
The LANCOM IAP-54 Wireless LAN connector supports the Power-over-
Ethernet standard (PoE). Further information about PoE is available in the
info box ’Power-over-Ethernet – elegant power supply through the LAN
wiring’ →page 17.
By activated DSLoL option, the LAN connector can also be used for con-
necting the LANCOM 54 Wireless base station to a broadband modem.
Connection for the serial configuration cable and access to the reset but-
ton, protected by an IP50 sealing cap.
The function of the reset button
The reset button has two different functions depending on how long it is
pressed:
Restarting the device (soft reset) – push the button for less than five
seconds. The device will restart.
Resetting the configuration (hard reset) – push the button for more
than five seconds. All the device’s LEDs will light up green and stay on. As
soon as the reset switch is released, the device will restart with factory set-
tings.

Hardware installation
2.4.1
LANCOM L-54g Wireless, LANCOM L-54ag Wireless
The installation of the LANCOM 54 Wireless base station takes place in max-
imum five steps:
Antennas – Screw on the both included diversity antennas at the back of
the LANCOM 54 Wireless base station.
LAN – You can first connect the LANCOM 54 Wireless base station to your
LAN. For that purpose, plug the included network cable (green plugs) into
the LAN connector of the device and the other end into a free network
connecting socket of your local network (resp. into a free socket of a hub/
switch). In this case, the node/hub switch
remains in the presetting
'node' (
).
Alternatively, you can connect also a single PC. In this case, turn the node/
hub switch
on 'hub' (
).
The LAN connector identifies automatically the transfer rate (10/100
Mbps) of the connected network device (autosensing).
For information about the installation of PoE see the info box ’Power-
over-Ethernet – elegant power supply through the LAN wiring’
→page 17.
DSLoL – If you want to use your LANCOM 54 Wireless base station in
DSLoL mode, you can either connect the device directly to the DSL modem
(exclusive mode) or to a hub resp. switch of the cable-bound LAN (auto-
matic mode).
For the exclusive mode insert the included network cable (green plugs)
into the LAN connector of the device and the other end into the cor-
responding interface of the DSL modem. In this case, turn the node/hub
switch
on 'hub' (
).
For the automatic mode for simultaneous operating with LAN and DSLoL
insert the included network cable (green plugs) into the LAN connector of
the device and the other end into a free network connecting socket of
LANCOM L- 54ag Wireless – LANCOM L- 54g Wireless – LANCOM IAP- 54 Wireless
Chapter 2: Installation
20
EN
your local network (resp. into a free socket of a hub/switch). In this case,
the node/hub switch
remains in the presetting 'node' (
).
Connect to power – Connect socket of the unit to a power supply
using the included power adapter.
Use the supplied power supply unit only! Using an unsuitable power
supply unit may cause damage or injury.
LAN interface: exclusive or in parallel for DSLoL
There are two principle DSLoL operation modes available. Either use the exclusive mode when
connecting your LANCOM 54 Wireless directly to a DSL modem, or use the automatic mode
when connecting the LANCOM 54 Wireless to a hub or switch of a cable-bound LAN, and
connect this hub/switch again to the DSL modem. If the LANCOM 54 Wireless is broadcasted
as gateway via DHCP, computers in LAN
and WLAN can use the internet connec-
tion simultaneously via one physical
interface. Set the desired mode in
LANconfig in the Interface settings of the
DSLoL interface.
DSLoL supports all PPPoE-based Internet access lines, as well as those that are
supplied with a access router with multiple fixed IP addresses (such as many SDSL
business lines).
Note the setting of the node/hub switch
If the node/hub switch for your application is not in the right position, no correct connection
will be established between the LANCOM 54 Wireless base station and other devices of the
cable-bound LAN and/or a DSL modem.
The node/hub switch is always in position 'node', when the LANCOM 54 Wireless base station
is connected to a network. The setting 'hub' is needed, when the base station will be directly
connected to another device like a single PC or a DSL modem.

Connecting up
Plug the supplied network cable (green plug) into the LAN connector of
the LANCOM IAP-54 Wireless and into the 'Data/Power Out' socket of the
PoE Power Injector.
Connect the 'Data In' connector on the PoE Power Injector with an avail-
able network socket of your local network (or a free socket of a hub or
switch). The cable to connect the PoE Power Injector to the LAN is not
supplied.
If the PoE Power Injector is not connected to a switch or hub but
directly to a computer’s network connector, please be sure to use a
suitable crossover cable.
Connect the PoE Power Injector to the power supply (as described in the
manual supplied with the PoE Power Injector).
After a brief self-test, the device illuminates the power LED on the
LANCOM IAP-54 Wireless with a steady green, or blinks alternately in
green and red if the configuration password has not been set.
Remove the sealing caps for the serial connector and reset button
The connector for the serial configuration cable and the reset button are
recessed into the housing and are protected by two black plastic screws.
If necessary, undo the sealing screws carefully with a suitable screwdriver.
After resetting or carrying out the configuration via the serial cable, you
should seal the device again carefully with the sealing screws.
Information about the function of the reset button can be found under ’The
function of the reset button’ →page 18.

Basic configuration
The basic configuration can be performed on a step-by-step basis using a
convenient setup wizard to guide you through the setup process and prompt
you for the required information.
First, this chapter will tell you which information is required for the basic con-
figuration. Use this section to assemble the information you will need before
you launch the wizard.
Next, enter the data in the setup wizard. Launching the wizard and the proc-
ess itself are described step by step — with separate sections for LANconfig
and WEBconfig. Thanks to the information that you have collected in advance,
the basic configuration is quick and effortless.
At the end of this chapter we will show you the settings that are needed for
the LAN's workstations to ensure trouble-free access to the router (’TCP/IP
settings to workstation PCs’ →page 34).
3.1
Which information is necessary?
The basic configuration wizard will take care of the basic TCP/IP configuration
of the router and protect the device with a configuration password. The fol-
lowing descriptions of the information required by the wizard are grouped in
these configuration sections:
TCP/IP settings
protection of the configuration
information related to the Wireless LAN
information on DSL connection
configuring connect charge protection
security settings
3.1.1
TCP/IP settings
The TCP/IP configuration can be realized in two ways: either as a fully auto-
matic configuration or manually. No user input is required for the fully auto-
matic TCP/IP configuration. All parameters are set automatically by the setup
wizard. During manual TCP/IP configuration, the wizard will prompt you for
the usual TCP/IP parameters: IP address, netmask etc. (more on these topics
later).
LANCOM L- 54ag Wireless – LANCOM L- 54g Wireless – LANCOM IAP- 54 Wireless
Chapter 3: Basic configuration
26
EN
Fully automatic TCP/IP configuration is only possible in certain network envi-
ronments. The setup wizard therefore analyses the connected LAN to deter-
mine whether it supports fully automatic configuration.
New LAN—fully automatic configuration possible
If all connected network devices are still unconfigured, the setup wizard will
suggest fully automatic TCP/IP configuration. This may be the case in the fol-
lowing situations:
a single PC is connected to the router
setup of a new network
Fully automatic TCP/IP configuration will not be available when integrating
the LANCOM 54 Wireless in an existing TCP/IP LAN. In this case, continue with
the section ’Information required for manual TCP/IP configuration’
→page 26.
The result of the fully automatic TCP/IP configuration: the router will be
assigned the IP address '172.23.56.1' (netmask '255.255.255.0'). In addition,
the integrated DHCP server will be enabled so that the LANCOM 54 Wireless
can automatically assign IP addresses to the devices in the LAN.
Configure manually nevertheless?
The fully automatic TCP/IP configuration is optional. You may also select man-
ual configuration instead. Make your selection after the following considera-
tions:
Choose automatic configuration if you are not familiar with networks and
IP addresses.
Select manual TCP/IP configuration if you are familiar with networks and
IP addresses, and one of the following conditions is applicable:
You have not yet used IP addresses in your network but would like to
do so now. You would like to specify the IP address for your router,
selecting it from the address range reserved for private use, e.g.
'10.0.0.1' with the netmask '255.255.255.0'. At the same time you
will set the address range that the DHCP server uses for the other
devices in the network (provided that the DHCP server is switched on).
You have previously used IP addresses for the computers in your LAN.
Information required for manual TCP/IP configuration
During manual TCP/IP configuration, the setup wizard will prompt you for the
following information:

IP address and netmask for the LANCOM 54 Wireless
Assign a free IP address from the address range of your LAN to the
LANCOM 54 Wireless and specify the netmask.
Enable DHCP server?
Disable the DHCP server function in the LANCOM 54 Wireless if you would
like to have a different DHCP server assign the IP addresses in your LAN.
3.1.2
Configuration protection
The password for configuration access to the LANCOM 54 Wireless protects
the configuration against unauthorized access. The configuration of the router
contains a considerable amount of sensitive information such as your Internet
access information. We therefore strongly recommend protecting it with a
password.
3.1.3
Settings for the Wireless LAN
The network name (SSID)
The basic configuration wizard asks for the network name of the base station
(often designated as SSID – Service Set Identifier). The network name will be
registered in the base stations of the Wireless LAN. You can choose any name.
Several base stations with the same network name form a common Wireless
LAN.
Open or closed Wireless LAN?
Mobile radio stations dial-in the wanted Wireless LAN by declaration of the
network name. The specification of the network name is facilitated by two
technologies:
Mobile radio stations can search for Wireless LANs in the environs
(„scan“) and offer for selection the found Wireless LANs in a list.
By using the network name 'ANY', the mobile radio station will enrol in
the next available Wireless LAN.
The Wireless LAN can be „closed“ to prevent this procedure. In this case, no
enrolment with the network name 'ANY' will be accepted.
For standard, LANCOM base stations are responsive under the net-
work name 'LANCOM'. The wireless basic configuration of a base sta-
tion takes therefore place via this network name. If another network
name is set during the basic configuration, also the Wireless LAN
LANCOM L- 54ag Wireless – LANCOM L- 54g Wireless – LANCOM IAP- 54 Wireless
Chapter 3: Basic configuration
28
EN
access of the configuring mobile base station must be changed to this
new network name after closing the basic configuration.
Selection of a radio channel
The base station operates in a certain radio channel. The radio channel will be
selected from a list of up to 11 channels in the 2,4 GHz frequency range or
up to 19 channels in the 5 GHz frequency range. (in various countries some
radio channels are restricted, see appendix).
The used channel and frequency range define the operating of the common
radio standard, in doing so the 5 GHz frequency range correspond to the IEEE
802.11a standard and the 2,4 GHz frequency range to the IEEE 802.11g and
IEEE 802.11b standard.
If no further base stations operate in reach of the base station, any radio
channel can be adjusted. Otherwise, the channels in the 2,4 GHz band must
be chosen in the way that they preferably do not overlap one another or have
a distance as great as possible respectively. The automatic setting is normally
enough in the 5 GHz band, in which the LANCOM 54 Wireless base station
itself adjust the best channel via TPC and DSF.
3.1.4
Connect charge protection
Connect charge protection blocks DSL connections that go beyond a previ-
ously set limit, thus protecting you from unexpectedly high connection
charges.
If you run the LANCOM 54 Wireless via DSL access with a flat-rate tarriff, you
can set the maximum connecting-time in minutes.
Any budget can be deactivated by entering the value '0.'
In basic settings the charge protection is defined to maximum 600
minutes within seven days. Adapt this setting to your personal needs
or deactivate the charge protection if you have arranged a flatrate
with your provider.

LANconfig automatically detects the new LANCOM 54 Wireless in the
TCP/IP network. Then the setup wizard starts that will help you make the
basic settings of the device or will even do all the work for you (provided
a suitable network environment exists).
If the setup wizard does not start automatically, start a manual search
for new devices on all ports (if the LANCOM 54 Wireless is connected
via a serial port) or in the network (Device Find).
If you cannot access an unconfigured LANCOM 54 Wireless, the prob-
lem may be due to the netmask of the LAN: with less than 254 possi-
ble hosts (netmask > '255.255.255.0'), please ensure that the IP
address 'x.x.x.254' is located in your own subnet.
If you have chosen automatic TCP/IP configuration, please continue with
Step .
If you would like to configure the TCP/IP settings manually, assign an
available address from a suitable address range to the LANCOM 54
Wireless. Confirm your choice with Next.
Specify whether or not the router should act as a DHCP server. Make your
selection and confirm with Next.
In the following window, specify the password for configuration access.
Note that the password is case-sensitive and ensure that it is sufficiently
long (at least 6 characters).
In addition, you may specify whether the device may only be configured
from the local network or whether remote configuration via the WAN (i.e.
a remote network) is also permissible.

Section ’TCP/IP settings to workstation PCs’ →page 34 will describe
the settings required for the individual workstations in the LAN.
3.3
Instructions for WEBconfig
To configure the router with WEBconfig you must know how to address it in
the LAN. The reaction of the devices, as well as their accessibility for configu-
ration via web browser is dependent on whether a DHCP server and a DNS
server are already active in the LAN, and whether these two server processes
exchange the assignment of IP addresses to symbolic names within the LAN
between each other.
After powered on, unconfigured LANCOM devices check first, whether a DHCP
server is already active in the LAN. Dependent on the situation, the device is
able to switch on its own DHCP server or, alternatively, to activate its DHCP
client mode. In this second operating mode, the device itself can obtain an IP
address from a DHCP server already existing in the LAN.
Network without DHCP server
In a network without DHCP server, unconfigured LANCOM devices activate
their own DHCP server service after starting, and assign appropriate IP
addresses and gateway information to the other workstations within the LAN,
provided that the workstations are set to obtain their IP address automatically
LANCOM L- 54ag Wireless – LANCOM L- 54g Wireless – LANCOM IAP- 54 Wireless
Chapter 3: Basic configuration

EN
(auto-DHCP). In this constellation, the device can be accessed with any web
browser from each PC with activated auto-DHCP function through the name
LANCOM or by its IP address 172.23.56.254.
If the configuration PC does not obtain its IP address from the LANCOM DHCP
server, figure out the current IP address of this PC (with Start Execute
cmd and command ipconfig at the prompt under Windows 2000 or Windows
XP, with Start Execute cmd and the command winipcfg at the prompt
under Windows Me and Windows 9x, or with the command ifconfig on the
console under Linux). In this case, the LANCOM is reachable under the IP
address x.x.x.254 ( “x” stands for the first three blocks in the IP address of
the configuration PC).
Network with DHCP server
If a DHCP server is active in the LAN to assign IP addresses, an unconfigured
LANCOM device will turn off its own DHCP server. It will change into DHCP
client mode and will obtain an IP address from the DHCP server of the LAN.
This IP address is not known at first. The accessibility of the device depends
on the name resolution:
If there is a DNS server for name resolution in the LAN, which inter-
changes the assignment of IP addresses to names with the DHCP server,
then the device can be accessed by the name “LANCOM ”
(e.g. “LANCOM-00a057xxxxxx”).
The MAC address can be found on a label at the bottom of the device.

If there is no DNS server in the LAN, or it is not linked to the DHCP server,
then the device can not be reached by the name. The following options
remain in this case:

Default gateway – receives all packets that are not addressed to comput-
ers within the local network.
DNS server – translates network names (www.lancom.de) or names of
computers (www.lancom.de) to actual IP addresses.
The LANCOM 54 Wireless can perform the functions of both a default gateway
and a DNS server. In addition, as a DHCP server it can also automatically
assign valid IP addresses to all of the computers in the LAN.
The correct TCP/IP configuration of the PCs in the LAN depends on the method
used to assign IP addresses within the LAN:
IP address assignment via the LANCOM 54 Wireless (default)
In this operating mode the LANCOM 54 Wireless not only assigns IP
addresses to the PCs in the LAN, it also uses DHCP to specify its own IP
address as that of the default gateway and DNS server. The PCs must
therefore be configured so that they automatically obtain their own IP
address and the IP addresses of the standard gateway and DNS server (via
DHCP).
IP address assignment via a separate DHCP server
The workstation PCs must be configured so that they automatically obtain
their own IP address and the IP addresses of the standard gateway and
DNS server (via DHCP). The IP address of the LANCOM 54 Wireless must
be stored on the DHCP server so that the DHCP server transmits it to the
PCs in the LAN as the standard gateway. In addition, the DHCP server
should also specify the LANCOM 54 Wireless as a DNS server.
Manual IP address assignment
If the IP addresses in the network are assigned static ally, then for each PC
the IP address of the LANCOM 54 Wireless must be set in the TCP/IP con-
figuration as the standard gateway and as a DNS server.
For further information and help on the TCP/IP settings of your
LANCOM 54 Wireless, please see the reference manual. For more
information on the network configuration of the workstation comput-
ers, please refer to the documentation of your operating system.

4.1
What does a router do?
Routers connect LANs at different locations and individual PCs to form a Wide
Area Network (WAN). With the appropriate rights, any computer in this WAN
can access the other computers and services of the complete WAN.
A special feature of the router is to send only the data with the connection of
the networks via WAN connection, that should reach the other network. All
other data is held back in its own network.
Connecting a LAN to the Internet does not differ technically from the coupling
of two LANs. The only difference is that not just a handful of computers, but
the ultimate WAN can be found behind the Internet provider's router.
All routers have at least two connections: one for the LAN and at least one for
WAN connections. In addition to the wireless interface for WLAN the models
in the LANCOM 54 Wireless series each also offer an 10/100 Mbps Ethernet
LAN interface, which can be used as DSLoL connector alternatively or simul-
taneously for WAN and LAN connectivity.
The task of a LANCOM 54 Wireless is to transfer data from the local network
to the target network via a suitable WAN connection. Data is also transferred
from the WAN to the desired recipients in the LAN.

Setting up the Internet access with DSLoL
All computers in the LAN can take advantage of the central Internet access of
the LANCOM 54 Wireless. The connection to the Internet provider can be
established via DSL connection. Therefore, the LAN connector of the LANCOM
54 Wireless is connected with a suitable DSL modem.
Does the setup wizard know your Internet provider?
A convenient wizard is available to help you set up Internet access for your
LANCOM 54 Wireless. The wizard knows the access information of major
Internet providers and will offer you a list of providers to choose from. If you
find your Internet service provider on this list, you normally will not have to
enter any further transmission parameters to configure your Internet access.
Only the authentication data (like user name and password) that are supplied
by your provider are required.
Additional information for unknown Internet providers
If the setup wizard does not know your Internet provider, it will prompt you
for all of the required information step by step. Your provider will supply this
information.
Connection to a DSL modem
protocol: PPPoE
Connection to an access router with fixed IP addresses
protocol: Plain Ethernet
Additional connection options
You may also enable or disable further options in the wizard, depending on
whether or not they are supported by your Internet provider:
Time-based billing or flat rate – select the accounting model used by your
Internet provider.
When using time-based billing, you can set the LANCOM 54 Wireless
to automatically close existing connections if no data has been trans-
ferred within a specified time (the so-called idle time).
In addition, you can activate a line monitor that identifies inactive
remote stations faster and therefore can close the connection before
the idle time has elapsed.

Security settings
Your LANCOM 54 Wireless base station has numerous security functions. You
find in this chapter all information needed for an optimal protection of the
base station.
5.1
Security for the Wireless LAN
Reflecting on Wireless LANs often entails substantial doubts concerning secu-
rity. Many people suppose that abuse of data transmitted via radio links is rel-
atively simple.
Wireless LAN devices by LANCOM Systems permit the employment of modern
security technologies:
Closed network
Access Control (via MAC-addresses)
LANCOM Enhanced Passphrase Security
Encryption of data transfer (802.11i/WPA or WEP)
802.1x / EAP
optional IPSec over WLAN (VPN), in combination with external VPN gate-
way
5.1.1
Closed network
Each Wireless LAN according to IEEE 802.11 has its own network name (SSID).
This network name serves as identification and enables administration of
Wireless LANs.
A Wireless LAN can be established in such a way that any user gets access to
this network. Such networks are called open networks. Any user can access
an open network also without knowledge of the WLAN network name
reserved specifically for this network. Only requirement is the input of the net-
work name 'ANY'.
In a closed network the access via 'ANY' is not possible. User have to specify
the correct network name. Unknown networks stay hidden to them.
Ad-hoc-networks are automatically installed as closed networks and cannot
be opened. Infrastructure networks can be run either in open or closed con-
dition. You make the settings for this at the respective base station.
LANCOM L- 54ag Wireless – LANCOM L- 54g Wireless – LANCOM IAP- 54 Wireless
Chapter 5: Security settings
41
EN
5.1.2
Access control via MAC address
Each network device has an special identification number. This identification
number is the so-called MAC address (Media Access Control), which is world-
wide unique per device.
The MAC address is programmed into the hardware and cannot be changed.
Wireless LAN devices by LANCOM Systems have got a MAC address label on
the casing.
The access to an infrastructure network can be restricted to known MAC
addresses for certain Wireless LAN devices solely. To do so, Access Control lists
are available within the LANCOM base stations, in which the granted MAC
addresses can be deposited.
This method of access control is not available for ad-hoc networks.
5.1.3
LANCOM Enhanced Passphrase Security
With LEPS (LANCOM Enhanced Passphrase Security) LANCOM Systems has
developed an efficient method which uses the simple configuration of IEEE
802.11i with passphrase and yet which avoids the potential error sources of
passphrase sharing. LEPS uses an additional column in the ACL to assign an
individual passphrase consisting of any 4 to 64 ASCII characters to each MAC
address. The connection to the access point and the subsequent encryption
with IEEE 802.11i or WPA is only possible with the right combination of pass-
phrase and MAC address.
LEPS can be used locally in the device and can also be centrally managed with
the help of a RADIUS server, and it works with all WLAN client adapters cur-
rently available on the market without modification. Full compatibility to
third-party products is assured as LEPS only involves configuration in the
access point.
An additional security aspect: LEPS can also be used to secure single point-
to-point connections (P2P) with an individual passphrase. Even if an access
point in a P2P installation is stolen and the passphrase and MAC address
become known, all other WLAN connections secured by LEPS remain pro-
tected, particularly when the ACL is stored on a RADIUS server.
5.1.4
Encryption of the data transfer
A special role comes up to the encryption of data transfer for Wireless LANs.
For IEEE 802.11 radio transfer the supplementing encryption standards are
all-guides
com
LANCOM L- 54ag Wireless – LANCOM L- 54g Wireless – LANCOM IAP- 54 Wireless
Chapter 5: Security settings
42
EN
802.11i/WPA and WEP. The function of the encryption is to ensure the security
level of cable-bound LANs also in Wireless LANs.
Use encryption on the data transferred in the WLAN. Activate the strong-
est possible encryption available to you ((802.11i with AES, WPA or WEP)
and enter the appropriate keys or passphrases into the access point and
the WLAN clients.
Regularly change the WEP keys in your access points. The passphrases for
802.11i or WPA do not have to be changed regularly as new keys are gen-
erated for each connection anyway. This is not the only reason that the
encryption with 802.11i/AES or WPA/TKIP is so much more secure than
the now aged WEP method.
If the data is of a high security nature, you can further improve the encryp-
tion by additionally authenticating the client with the 802.1x method
(’802.1x / EAP’ →page 43) or activate an additional encryption of the
WLAN connection as used for VPN tunnels (’IPSec over WLAN’
→page 44). In special cases, a combination of these two mechanisms is
possible.
Further details to WLAN security and the used encoding methods can
be found in the LCOS reference manual.
Please take note of the information in the box “Standard WEP encryp-
tion“.

802.1x / EAP
The international industry standard IEEE 802.1x and the Extensible Authenti-
cation Protocol (EAP) enables the realization of reliable and secure access
controls for base stations. The access data is centrally administered on a
RADIUS server then, and can be retrieved by the base station if required.
Standard WEP encryption
As of LCOS version 4.0, WEP128 encryption is activated for every uncon-
figured device as standard.
The key consists of the first letter “L” followed by the LAN MAC address of
the access point in ASCII characters. The LAN MAC addresses of the
LANCOM devices always begin with the character string “00A057”. You
will find the LAN MAC address on a sticker on the base of the device. Only
use the number labeled as “MAC address” that starts with “00A057”. The
other numbers that may be found are not the LAN MAC address!
A device with the LAN MAC address “00A0570FB9BF” thus has a standard
WEP key of “L00A0570FB9BF”. This key is entered into the 'Private WEP
settings' of the device for each logical WLAN network as 'Key 1'.
To use a WLAN adapter to establish a connection to a new LANCOM
access point, the WEP128 encryption must be activated for the WLAN
adapter and the standard 13-character WEP key entered.
Note that a reset also causes the WLAN key settings to be lost
from the device and the standard WEP key comes into effect
again. WLAN access can only work after a reset if the standard
WEP key is programmed into the WLAN adapter as well.

Moreover, this technology makes enables a secured dispatch and a regular
automatic change of WEP keys. In this way IEEE 802.1x improves the protec-
tion efforts of WEP.
In Windows XP the IEEE-802.1x technology is already integrated by default.
For other operating systems 802.1x client software is available.
5.1.6
IPSec over WLAN
By means of IPSec over WLAN a radio network can be optimally secured in
addition to the already introduced securing mechanisms.
In order to run IPSec over WLAN you have to upgrade the base stations of the
with the LANCOM VPN option and the LANCOM Advanced VPN Client, which
runs under the operating systems Windows 98ME, Windows 2000 and Win-
dows XP. For other operating systems client software from other manufactur-
ers is available. The drivers for the LANCOM AirLancer wireless adapter are
already equipped with a 802.1x client.
5.1.7
Tips for handling keys
The security of encryption procedures can be substantially increased the by
paying attention to some important rules for handling keys.
Keep keys as secret as possible.
Never note a key. Popular, but completely unsuitable are for example:
notebooks, wallets and text files in PCs. Do not share a key unnecessarily.
Select a random key.
Use randomized keys of character and number sequences. Keys from the
general linguistic usage are insecure.
Change a key immediately in case of suspicion.
It is time to change the key of the Wireless LAN if an employee with access
to a key leaves your company. The key should also be renewed in case of
smallest suspicion of a leak.
5.2
The security settings wizard
Access to the configuration of a device permits not only to read out critical
information such as WEP key or Internet password. Rather, also the entire set-
tings of the security functions (e.g. firewall) can be altered then. So an unau-
thorized configuration access endangers not only a single device, but the
entire network.
LANCOM L- 54ag Wireless – LANCOM L- 54g Wireless – LANCOM IAP- 54 Wireless

Your LANCOM 54 Wireless has a password protection for the configuration
access. This protection is already activated during the basic configuration by
entering a password.
The device locks access to its configuration for a specified period of time after
a certain number of failed log-in attempts. Both the number of failed attempts
and the duration of the lock can be set as needed. By default, access is locked
for a period of five minutes after the fifth failed log-in attempt.
Besides these general settings you can also check the security settings of the
wireless network with the security wizard as far as your device has a WLAN
interface.
5.2.1
Wizard for LANconfig
Mark your LANCOM 54 Wireless in the selection window. Select from the
command bar Extras Setup Wizard.
Select in the selection menu the setup wizard Control Security Settings
and confirm your choice with Next.
Enter your password in the following windows and select the allowed pro-
tocols for the configuration access from local and remote networks.
In a next step parameters of the configuration lock like number of failed
log-in attempts and the duration of the lock can be adjusted.
Now you can set the security settings for the WLAN. These include the
name of the wireless network, the closed network function and the WEP
encryption. You can type in the parameters for both wireless networks
separately on devices with the option of a second WLAN interface.
Now you specify filter lists for stations (ACL) accessing the WLAN and pro-
tocols. Thereby, you restrict data exchange between the wireless network
and the local network.

The firewall wizard
The LANCOM 54 Wireless incorporates an effective protection of your LAN
and WLAN when accessing the Internet by its Stateful Inspection firewall and
its firewall filters. Basic idea of the Stateful Inspection firewall is that only self-
initiated data transfer is considered allowable. All unasked accesses, which
were not initiated from the local network, are inadmissible.
The firewall wizard assists you to create new firewall rules quickly and com-
fortably.
Please find further information about the firewall of your LANCOM 54
Wireless and about its configuration in the reference manual.

The security checklist
In the following checklist you will find an overview of the most important
security functions. That way you can be quite sure not to have overlooked any-
thing important during the security configuration of your LANCOM.
Have you assigned a password for the configuration?
The simplest option for the protection of the configuration is the estab-
lishment of a password. As long as a password hasn't been set, anyone
can change the configuration of the device. The box for entering the pass-
word is located in LANconfig in the 'Management' configuration area on
LANCOM L- 54ag Wireless – LANCOM L- 54g Wireless – LANCOM IAP- 54 Wireless
Chapter 5: Security settings
48
EN
the 'Security' tab. It is particularly advisable to assign a password to the
configuration if you want to allow remote configuration.
Have you permitted remote configuration?
If you do not require remote configuration, then deactivate it. If you
require remote configuration, then be sure to assign a password protec-
tion for the configuration (see previous section). The field for deactivating
the remote configuration is also contained in LANconfig in the 'Manage-
ment' configuration area on the 'Security' tab.
Have you permitted the configuration by the wireless network?
If you do not require configuration by the wireless network, then deacti-
vate it. The field for deactivating the configuration by the wireless network
is also contained in LANconfig in the 'Management' configuration area on
the 'Security' tab. Select here under 'Access rights - from Wireless LAN'
for all types of configuration the option 'not allowed'.
Have you assigned a password to the SNMP configuration?
Also protect the SNMP configuration with a password. The field for pro-
tection of the SNMP configuration with a password is also contained in
LANconfig in the 'Management' configuration area on the 'Security' tab.
Have you activated the Firewall?
The Stateful Inspection Firewall of the LANCOM ensures that your local
network cannot be attacked from the outside. The Firewall can be enabled
in LANconfig under ’Firewall/QoS’ on the register card ’General’.
Do you make use of a ’Deny All’ Firewall strategy?
For maximum security and control you prevent at first any data transfer
through the Firewall. Only those connections, which are explicitly desired
have to allowed by the a dedicated Firewall rule then. Thus ’Trojans’ and
certain E-mail viruses loose their communication way back. The Firewall
rules are summarized in LANconfig under ’Firewall/Qos’ on the register
card ’Rules’. A guidance can be found in the reference manual.
Have you activated the IP masquerading?
IP masquerading is the hiding place for all local computers for connection
to the Internet. Only the router module of the unit and its IP address are
visible on the Internet. The IP address can be fixed or assigned dynami-
cally by the provider. The computers in the LAN then use the router as a
gateway so that they themselves cannot be detected. The router separates
Internet and intranet, as if by a wall. The use of IP masquerading is set
individually for each route in the routing table. The routing table can be
LANCOM L- 54ag Wireless – LANCOM L- 54g Wireless – LANCOM IAP- 54 Wireless
Chapter 5: Security settings
49
EN
found in the LANconfig in the 'IP router' configuration section on the
'Routing' tab.
Have you closed critical ports with filters?
The firewall filters of the LANCOM 54 Wireless devices offer filter functions
for individual computers or entire networks. Source and target filters can
be set for individual ports or for ranges of ports. In addition, individual
protocols or any combinations of protocols (TCP/UDP/ICMP) can be fil-
tered. It is particularly easy to set up the filters with LANconfig. The 'Rules'
tab under 'Firewall/QoS' can assist you to define and change the filter
rules.
Have you excluded certain stations from access to the router?
Access to the internal functions of the devices can be restricted using a
special filter list. Internal functions in this case are configuration sessions
via LANconfig, WEBconfig, Telnet or TFTP. This table is empty by default
and so access to the router can therefore be obtained by TCP/IP using Tel-
net or TFTP from computers with any IP address. The filter is activated
when the first IP address with its associated network mask is entered and
from that point on only those IP addresses contained in this initial entry
will be permitted to use the internal functions. The circle of authorized
users can be expanded by inputting further entries. The filter entries can
describe both individual computers and whole networks. The access list
can be found in LANconfig in the 'TCP/IP' configuration section on the
'General' tab.
Is your saved LANCOM configuration stored in a safe place?
Protect the saved configurations against unauthorized access in a safe
place. A saved configuration could otherwise be loaded in another device
by an unauthorized person, enabling, for example, the use of your Inter-
net connections at your expense.
Have you secured your wireless network encryption, an ACL and
LEPS?
With the help of 802.11i, WPA or WEP, you can encrypt the data in your
wireless network with different encryption methods such as AES, TKIP or
WEP. LANCOM Systems recommends the strongest possible encryption by
using 802.11i and AES. If the WLAN client adapters do not support these,
then you should use TKIP or at least WEP. Make sure that the encryption
function in your device is activated, and that at least one passphrase or
WEP key has been entered and selected for application.
LANCOM L- 54ag Wireless – LANCOM L- 54g Wireless – LANCOM IAP- 54 Wireless
Chapter 5: Security settings
50
EN
As of LCOS version 4.0, WEP128 encryption is activated for every
unconfigured device as standard (’Standard WEP encryption’
→page 43).
To check the WEP settings, open LANconfig, go to the configuration area
and select 'WLAN security' on the '802.11i/WEP' tab to view the encryp-
tion settings for the logical and physical WLAN interfaces.
With the Access Control List (ACL) you can permit or prevent the access to
your wireless LAN by individual clients. The decision is based on the MAC
address that is permanently programmed into wireless network adapters.
To check the Access Control List, go to the configuration area in
LANconfig and select 'WLAN security' on the 'Stations' tab.
The LANCOM Enhanced Passphrase Security (LEPS) uses an additional col-
umn in the ACL to assign an individual passphrase consisting of any 4 to
64 ASCII characters to each MAC address. The connection to the access
point and the subsequent encryption with IEEE 802.11i or WPA is only
possible with the right combination of passphrase and MAC address.
Have you set the 802.1x functions for particularly sensitive data
exchange in the wireless network?
If you have a particularly sensitive data exchange in your wireless net-
work, you can use the IEEE-802.1x technology for a more extensive pro-
tection. To control or to activate the IEEE-802.1x settings, select in
LANconfig the configuration area 'User registration'.

Options and accessories
Your LANCOM 54 Wireless base station has numerous extensibilities and the
possibility to use a broad choice of LANCOM accessories. You find in this
chapter information about the available accessories and how to use them
with your base station.
The range of the base station can be increased by optional antennas of
the AirLancer Extender series and can be adapted to special conditions of
environs.
With the LANCOM Public Spot Option option it is possible to extend the
LANCOM 54 Wireless for additional billing and accounting functions in
order to upgrade it to a Wireless Public Spot.
6.1
Optional AirLancer Extender antennas
To increase the range of the LANCOM 54 Wireless base station or to adapt the
base station to special conditions of environs, you can connect AirLancer
Extender antennas at the base station. An overview of suitable antennas can
be found on the LANCOM web site under www.lancom.de.
For installation of an optional AirLancer Extender antenna turn off the
LANCOM 54 Wireless by pulling out the power supply cable of the device.
Remove now carefully the two diversity antennas on the back by screwing
them out. Connect the AirLancer Extender antennas to the antenna connector
with the inscription ’Antenna Main’.

LANCOM Public Spot Option
Wireless public spots are publicly accessible points, at which users with their
own mobile computers can dial wirelessly into a network, usually into the
Internet.
The Wireless LAN technology is ideally suitable to offer wireless Internet serv-
ices to the public at places such as airports, hotels, stations, restaurants or
cafés, so-called Public Hot Spots. The LANCOM Public Spot Option is intended
for operators of public wireless networks, and unveils additional functions for
authentication and billing of public Internet services for the LANCOM 54
Wireless base station, thus enabling a simple set-up and maintenance of pub-
lic hot spots.
The authentication and billing of the individual users is realized via user-
friendly web sites, so that client PCs with a Wi-Fi certificated radio card (e.g.
AirLancer) and a standard Internet browser can directly go online.
The LANCOM Public Spot Option is the optimal solution for public Wireless
LANs. Wireless LANs are very suitable for company networks and for wireless
networking at home. But for public access services, there is a lack of mecha-
nisms for authentication and billing of single users (AAA - Authentication /
Authorisation / Accounting). This lack remedies the LANCOM Systems Open
User Authentication (OUA), the main part of the LANCOM Public Spot Option.
The OUA procedure realizes the authentication of all wireless clients via user
name and password, and checks the authorization of single users via RADIUS.
Accounting data (online time and data volume) can be transferred per user
and per session to a central RADIUS server. Client PCs need only radio card
(e.g. AirLancer), TCP/IP and an Internet browser. Additional software is not
needed. Therefore, the public spot option is ideally suitable to install wireless

Internet access services in hotels, restaurants, cafés, airports, stations, exhi-
bition centres or universities.

Troubleshooting
In this chapter, you will find suggestions and assistance for a few common dif-
ficulties.
7.1
No WAN connection is established
After start-up the router automatically attempts to connect to the access pro-
vider. During this process, the Online LED will blink green. If successful, the
LED will switch over to steady green. If, however, the connection can't be
established, the Online LED will light up red. The reason for this is usually one
of the following:
Problems with the cabling?
Only the cable provided with your device should be used to connect to the
WAN. This cable must be connected to the Ethernet port of your broadband
access device. The WAN link LED must light green indicating the physical con-
nection.
Has the correct transfer protocol been selected?
The transfer protocol is set along with the basic settings. The basic setup wiz-
ard will enter the correct settings for numerous DSL providers automatically.
Only if your DSL provider is not listed, you will have to enter manually the pro-
tocol being used. In any case, the protocol that your DSL provider supplies you
with should definitely work.
You can monitor and correct the protocol settings under:
7.2
DSL data transfer is slow
The data transfer rate of an broadband (Internet) DSL connection is dependent
upon numerous factors, most of which are outside of one's own sphere of
influence. Important factors aside from the bandwidth of one's own Internet
connection are the Internet connection and current load of the desired target.

EN
Numerous other factors involving the Internet itself can also influence the
transfer rate.
Increasing the TCP/IP window size under Windows
If the actual transfer rate of a DSL connection is significantly below the fastest
rate listed by the provider, there are only a few possible causes (apart from the
above-mentioned external factors) which may involve one's own equipment.
One common problem occurs when large amounts of data are sent and
received simultaneously with a Windows PC using an asynchronous connec-
tion. This can cause a severe decrease in download speed. The cause of this
problem is what is known as the TCP/IP receive window size of the Windows
operating system that is set to a value too small for asynchronous connec-
tions.
Instructions on how to increase the Windows size can be found in the Knowl-
edge Base of the support section of the LANCOM web site (www.lancom.de).
7.3
Unwanted connections under Windows XP
Windows XP computers attempt to compare their clocks with a timeserver on
the Internet at start-up. This is why when a Windows XP in the WLAN is
started, a connection to the Internet is established by the LANCOM.
To resolve this issue, you can turn off the automatic time synchronization on
the Windows XP computers under Right mouse click on the time of day
Properties Internet time.
