| 9 Introduction The advantages of wireless LANs are obvious: Notebooks and PCs can be set up where they are wanted—problems with missing ports or construction alterations are a thing of the past with wireless networking. Network links in conferences or presentations, access to resources in adjacent buildings and exchanging data with mobile units are only a few of the options available with a wireless LAN. The access point plays the central role in enabling these options in an existing wired network.
Introduction EN 1.1 | The basic functions of a wireless network This chapter introduces the basic functional principles of a wireless network. The terms used will be explained and the structure and possible applications of wireless networks introduced. Detailed information on this and other topics can be found in the electronic documentation on the CD. Wireless network adapters WLAN Wireless network adapters connect individual notebooks and PCs to a Local Area Network (LAN).
Introduction 11 EN | Ad hoc network Ad hoc network This application is generally called a peer-to-peer network. In the language of wireless networking, it is known as an ad hoc network. Infrastructure network All computers with wireless network cards are able to access a wired network via an access point. The access point acts as the connection between the LAN and the WLAN and it also forms the switching center for data traffic within the WLANs.
Introduction | EN 12 Radio cells can also overlap to ensure good coverage. Different channels (up to 13 channels are available) can be selected to prevent interference between the cells. WLAN and ISDN/DSL gateway The LANCOM Wireless IL-11 access point offers a special supplementary function. The access point connects both the wireless network and the wired or DSL network simultaneously to the ISDN network via the ISDN interface.
| 13 What does the LANCOM Wireless offer? The following is an outline of the principal features of the device giving you a quick overview of its capabilities. Easy installation • • • • • • Connect the LANCOM Wireless to the power supply. Establish a link to the LAN. Connect to a DSL port. Plug in the ISDN cable. (LANCOM Wireless IL-11) Switch it on. Go! LAN connection Access points for wireless networks by LANCOM Systems work in Ethernet environments.
Introduction | EN Configuration Setting up and configuring the devices to your specific needs is made quick and easy in Windows operating systems by the configuration tool supplied, LANconfig. The management tool WEBconfig is just as easy to use. It allows you to access the configuration of the LANCOM Wireless access point or even load new firmware using any HTML browser. Furthermore it is possible to access device configuration via SNMP, Telnet and TFTP.
Introduction 15 less IL-11). Authentication mechanisms in PPP, firewall filters and IP masquerading complete the security concept. Furthermore, login barring prevents any “brute force attacks” and denies access to the router after a configurable number of login attempts using an incorrect password. Wireless and secure with WEP The WEP (Wired Equivalent Privacy) encryption method attaches a 40-bit or 128-bit key to the wireless data.
Introduction | EN Channel bundling and compression (LANCOM Wireless IL-11) The device supports static and dynamic channel bundling via MLPPP and BACP on the ISDN line. Stac data compression (hi/fn) can be used to achieve increases in the data transfer rate of up to 400% in case that the remote site also supports this compression. LANmonitor Under Windows operating systems, this tool displays the status of the router on the screen at all times.
| Introduction 17 LED indicators on the front of your access point allow you to monitor the ISDN and Ethernet connections and the current line connections, thus simplifying the process of diagnosing any systems failures. Statistics The comprehensive statistics function lets you keep track of your LANCOM Wireless. These statistics give you all the information you need on the data packets transferred, for example, so that you can optimize the configuration of your device.
EN 18 Introduction | throughout the network without the need to add hardware to the workstations. The office communications software simply needs to be loaded onto the individual workstations. A fax device is simulated at the workstation so that faxes can be sent. With the LANCAPI, the PC forwards the fax via the network to the router which establishes the connection to the recipient.
Introduction 19 to determine the incorrect configuration of the computer or router quickly and allocate the resulting expenses to their appropriate causes.
Introduction | EN Roaming The roaming feature lets you construct bigger wireless networks using any number of access points. When stations switch from one wireless cell to another while connected, they are automatically logged off of the previous access point and logged onto the next.
| 21 Installation This section will help you to connect as quickly as possible. First we will describe the contents of the package and introduce the device itself. After that we will explain how to connect the unit and put it to use quickly. The following information is intended for experienced users familiar with hardware and network configuration. 2.1 Package contents Please ensure that the delivery is complete before beginning with the installation.
EN 2.3 | Installation Install TCP/IP on your workstation To establish a connection to a LANCOM Wireless access point for the first time, the TCP/IP protocol has to be set up. The following describes how to install this protocol on various operating systems. 2.3.
Installation 23 Start / Settings / Control panel / Network / TCP/IP / Properties / Gateway and DNS configuration. Also enter a host name on the DNS configuration page. In doing so, use the name of the PC, which ideally matches the user's name, to maintain a certain amount of consistency. • 2.3.2 Checking the IP configuration Under Windows 95 and Windows 98, you can view the current IP configuration of your computer with by using Start / Run / winipcfg.
| Installation EN 24 Assign unique IP addresses, for example taken from a reserved range of addresses. For example, the workstations can be assigned addressed from '10.1.1.2' to '10.1.1.253', the router can be given '10.1.1.1' and all can have the subnet mask of '255.255.255.0'. To test whether or not a specific IP address, such as '10.1.1.1', is free, enter ping 10.1.1.1 in a DOS session. If you do not receive a response, the address is most likely free.
Installation 25 EN | • 2.3.3 Checking the IP configuration Under Windows NT 4.0 you can query the current IP configuration of your computer with Start / Run / ipconfig. This shows you which IP address was assigned to the computer by the DHCP server and which addresses have been specified for the gateway (not for the DNS server). Windows 2000 With Windows 2000, helpful hardware setup wizards provide support when you install the new hardware.
Installation | EN d The dialog that appears contains a list box containing the installed network components. TCP/IP should be listed in any case. e Select its entry and click the Properties... button. This opens a dialog where you can define all of the properties for this network protocol. The procedures for setting address, DHCP, gateway and DNS are the same here as in Windows 98. 2.4 Introducing the LANCOM Wireless This section introduces the unit's hardware.

LANCOM also provides a Linux version of LANconfig which can be downloaded from their website. a Install the TCP/IP network protocol on the computer that will be used to set up your device. b Then install LANconfig.
EN 2.7.1 | Installation The wizards The following wizards, which make it very easy to set up and configure the LANCOM Wireless, are available in LANconfig and WEBconfig: • • • • • • Basic settings Changing security settings Setting up Internet access Selecting the Internet provider Preparing remote access service (RAS) (LANCOM Wireless IL-11) Connecting two local networks (LANCOM Wireless IL-11) Wizards in LANconfig a Start the software LANconfig with Start / Programs / LANCOM / LANconfig.
Installation 33 The start page for automatic configuration does not appear in all described cases. In some cases you are asked to enter an IP address in the next step (c). a Start the new software with Start / Programs / LANCOM / LANconfig. b Select the option 'All settings to be defined automatically' if you are not familiar with networks and IP addresses and one of the following conditions applies: • You have not yet used IP addresses in your network but would like to do so starting now.
Installation | EN • • You have not yet used IP addresses in your network but would like to do so starting now. However, you wish to set the IP address for the router and assign it an address from an address range reserved for private use, e.g. '10.0.0.254' with the network mask '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 (so long as the DHCP server is not switched off).
| Installation 35 EN From this point on, the procedure is the same as for the LANconfig. Telnet Open a telnet connection to the address '10.0.0.254' if you have not used IP addresses in your network to date, or the address 'x.x.x.254', in which 'x.x.x' stands for the address range previously used in the network. Procedure example: a Start the telnet connection by clicking Start / Run and entering telnet 10.0.0.254 on the command line.
EN 36 Installation | With these settings, you have completed making your new router known on the local network. The router itself is addressable using the IP address of '10.0.0.1'. After you reboot your system, all units on the local network will be assigned IP addresses by the DHCP server in the router. It will use an address pool from '10.0.0.2' to '10.0.0.253' automatically.
| 37 Configuration and management LANCOM Wireless access points are always delivered with up-to-date software in which a number of the settings have already been prepared for you. It will nevertheless be necessary for you to add some information and configure the router to your specific needs. These settings are made as part of the configuration process. This section will show you the programs and routes you can use to access the device and set it up.
Configuration and management | EN Once LANconfig has finished its search, it displays a list of all the devices it has found, together with their names and perhaps a description, the IP address and its status. Two different display options can be selected for configuring the devices with LANconfig: • • The 'simple display' mode only shows the settings required under normal circumstances. The 'complete display' mode shows all available configuration options.
| Configuration and management 39 A LANCOM Wireless that has not be reconfigured or has been reset will even respond to all IP addresses. A prerequisite is that the last set of numbers in the IP address is '254' (e.g. http://10.0.0.254 and http://192.168.0.254). Extensive, context-sensitive documentation for each WEBconfig page and field is available at all times in WEBconfig by selecting the 'Help (Reference Manual)' link. 3.4 Configuration using Telnet Start up the configuration (e.g.

• • Configuration and management 41 '172.17.17.18', if you have not defined an IP address for the PPP client. The LANCOM Wireless IL-11 automatically uses this address if no other address has been defined. The calling PC then responds to the IP address '172.17.17.17'. Raise the IP address of the PC by one, if you have defined an address. For example: If you have defined the IP address '10.0.200.123' for the PPP client, the LANCOM Wireless IL-11 will respond to '10.0.200.124'.
Configuration and management | EN c Enter a calling number of your connector as the calling number in the 'configuration access' area, which is not used for other purposes. Alternatively, enter the following command: set /setup/config-module/Farconfig 123456 d You can protect the configuration of the device by assigning a password. Alternatively, enter the following command during a Telnet or terminal connection: passwd You will then be prompted to enter and confirm a new password. 3.
| 43 New firmware with FirmSafe The software in the LANCOM Wireless device is constantly being updated. We have fitted the devices with a flash ROM which makes child's play of updating the operating software so that you can enjoy the benefits of new features and functions. No need to change the EPROM, no need to open up the case: simply load the new release and you're away. 3.7.
EN 3.7.2 Configuration and management | How to load new software There are various ways of carrying out a firmware upload (which is the term given to the installation of software), all of which produce the same result: • • • LANconfig WEBconfig TFTP All settings will remain unchanged by a firmware upload. All the same you should save the configuration first for safety's sake (with Edit / Save configuration to file if using LANconfig, for example).
| Configuration and management 45 With TFTP you can use the writeflash command to install new firmware. To transmit a new firmware version to a device with the IP address 194.162.200.17, you would enter the following command under Windows NT for example: tftp -i 194.162.200.17 put lc_wl1iu.200 writeflash This command sends the corresponding file to the input IP address using the writeflash command. Binary file transfer must be set for TFTP. However, many systems have the ASCII format preset.

| 49 Operating modes and functions This section is an introduction to the functions and operating modes of your device.
EN 4.1.1 Operating modes and functions | Considerations for setting up a wireless network When designing networks for several access points, first determine where the access points will be positioned and how far apart they will be from each another. To ensure that the infrastructure of your wireless cells is free of gaps, use a mobile computer and the AirLancer Client Manager to test the wireless connections within the planned range.
Operating modes and functions 51 In Windows, set up Client for Microsoft Networks and file printer sharing under the Network Neighbourhood properties. If you want to use TCP/IP as your network protocol, be sure it is installed. 4.1.3 Infrastructure network Define the wireless connection between the computers with AirLancer MC11 and the access point in the configuration profile using the AirLancer Client Managers. a Select the Add/Edit Configuration Profile command in the 'Action' menu.
EN 4.1.4 Operating modes and functions | Point-to-point network On a point-to-point network, two or more access points communicate with each other. When configuring mobile stations, proceed exactly as you would for setting up an infrastructure network. It is also possible to connect pointto-point networks and infrastructure networks. For the access points in this case, however, both the network name and the radio frequency have to be the same and interpoint communication has to be enabled.
• • Operating modes and functions 53 PPP list Here enter the device name and/or user name of the remote station and the password for the connection. If the user name is different from the device name, enter the user name here as well. Be sure that authentication is set to 'None'. This refers to the local authentication of the remote station. The LANCOM, not the provider, has to log on. IP router module Here define the default route in the routing table.
EN 54 Operating modes and functions • • | the user name is different from the device name, enter the user name here as well. Be sure that no check is executed. PTPP list Here enter the device name of the remote station and its IP address and the port address (usually 1.723). Similar to the name list enter an idle time (default 300 seconds ). IP router module Here define the default route in the routing table. This should match the device name defined in the name list.
Operating modes and functions 55 ule/passw.required menu. In this case, the password itself is set with the command passwd. Login barring The configuration in the LANCOM Wireless is protected against “brute force attacks” by barring logins. A brute-force attack is the attempt of an unauthorized person to crack a password to gain access to a network, a computer or another device.
EN 4.2.2 Operating modes and functions | Security for your WLAN The security of wireless data also can be guaranteed using various techniques: • Station filter • Using a closed network • Data encryption You can also call up the wizards provided in WEBconfig or LANconfig to configure the basic security settings. Station filter When defining an access list, specify which clients are allowed access to the access point.
Operating modes and functions 57 guished. As an alternative to the alphanumeric keys, a 10-digit hexadecimal value can be assigned. Alphanumeric key Hexadecimal key For example: Seku1 For example: 0xABCD1234FE In order to encode data communication, the same keys must be used for all client stations and access points. Write down the assigned keys and store them in a secure location. The keys entered in the dialog box are only displayed when data is first input.
EN Object list Operating modes and functions | Use the object list to define the objects to be filtered. The following may apply as objects: • • • • Protocols Individual computers Entire networks Services Any and all of these elements may be combined. Furthermore, objects can be defined recursively. In this manner, for example, you could define objects for the TCP and UDP protocols.
Operating modes and functions 59 Host names can be used only if LANCOM Wireless can resolve the names into IP addresses. To do so, LANCOM Wireless has to have learned the names via DHCP or NetBIOS, or the assignment has to be entered statically in the DNS or IP-routing table. An entry in the IP-routing table can simultaneously assign a host name to an entire net. Filter list The filter list is constructed of the object and rule lists.
Operating modes and functions | EN under the /Setup/WAN-module/Security menu. You have a choice of the following: • • • • All calls are accepted from any remote station. Name: Only calls from those remote stations entered in the name list are accepted. Number: Only calls from those remote stations entered in the number list are accepted. Name or number: Only calls from those remote stations entered in the name list or number list are accepted.
Operating modes and functions 61 In PPP connections, the name and password is sent to the remote station during the call establishment, in the Dial-up Networking connection window for example. The device name, password and user name in the PPP list are used if the router establishes the connection itself. Checking the number Access to your own network is granted if the call number appears in the number list, or the caller is called back if the callback option is activated.
Operating modes and functions | EN separates Internet and intranet, as if by a wall. Therefore, IP masquerading is also called a “firewall function”. For further information, see the 'IP routing: IP masquerading' section. 4.3 ISDN routing (LANCOM Wireless IL-11) Data communications between two ISDN terminal devices takes place via ISDN connections. These connections can be realized either as dial-up or leased-line connections.
Operating modes and functions 63 address over the LAN to the router. Using the IP address, the router then searches the IP routing table and finds the remote station that belongs to the address, for example 'Provider_A'. Using this name, the router then checks the ISDN name list and finds the call number for the corresponding remote station that can be reached by ISDN, including the communication layer that is to be used.
Operating modes and functions | the last data has been exchanged across static connections for the holding time B1. • the data throughput has dropped below a specified level for the holding time B2 in dynamic connections. Layer name The layer stands for a collection of protocols to be used for this connection. The layer must be set up identically on both sides of the connection.
| 65 Router interface settings The router interface settings for the LANconfig can be found in the 'Communication' configuration section on the 'General' tab, or under /Setup/ WAN-module/Router-interface-list during Telnet or terminal sessions. The router interface settings determine the parameters to be used for each interface (i.e. each S0 port) while in router mode. These parameters do not apply to the other operating modes of the units.
Operating modes and functions | • Encapsulation Specify here whether an Ethernet header should be added to the data packets. Normally the setting 'Transparent' will be sufficient; this setting may only be required for HDLC connections to third-party devices. • Layer-3 Layer-3 protocol for the connection.

Operating modes and functions 67 4.4 Automatic address administration with DHCP In LANCOM Wireless L-11 this funktion is included when using the DSL firmware In order to operate smoothly in a TCP/IP network, all the devices in a local network must have unique IP addresses. They also need the addresses of DNS server and NBNS server as well as that of a default gateway through which the data packets are to be routed from addresses that are not available locally.
EN 4.4.2 Operating modes and functions | DHCP—'on', 'off' or 'auto'? The DHCP server can be set to three different states: • • • 'on': The DHCP server is permanently active. The configuration of the server (validity of the address pool) is checked when this value is entered. • When correctly configured, the device will be available to the network as a DHCP server. • In the event of an incorrect configuration (e.g. invalid pool limits), the DHCP server is disabled and switches to the 'off' state.
Operating modes and functions 69 an IP address. If the computer was already assigned an IP address at some point in the past, it requests this same address and the DHCP server attempts to reassign it this address if it has not already been assigned to another computer. The DHCP server also checks whether the address selected is still available in the local network. As soon as the uniqueness of an address has been established, the requesting computer is assigned the address found.
EN 70 Operating modes and functions | these addresses. In order for the computer to keep from constantly losing its addresses (above all its IP address), it applies for an extension ahead of time that it is generally sure to be granted. The computer loses its address only if it is switched off when the period of validity expires. For each request, a host can ask for a specific period of validity. However, a DHCP server can also assign the host a period of validity that differs from what it requested.
Operating modes and functions 71 Click Start / Settings / Control Panel / Network. Select the 'TCP/IP' entry for your network adapter and open Properties. You can now enter the desired values by selecting the various tabs. The assignment of IP addresses to the various computers can be checked using the 'Setup/DHCP/Table-DHCP' item in the DHCP module. This table contains the assigned IP address, the MAC address, the validity, the name of the computer (if available) and the type of address assignment.
EN 72 Operating modes and functions | a Connect the unconfigured device to your local network using a network cable. b Switch the device on. It will not find any other DHCP servers in the network and will thus enable its own DHCP functions. c If you have not done so already, install the TCP/IP protocol on all computers in the LAN. • • Usually when the protocol is installed, the default configuration is such that the computers are automatically ready to obtain the IP address from a DHCP server.
Operating modes and functions 73 EN | d Install the LANconfig on a computer in the network. e Start the program from the 'LANCOM' program group. When loading, the LANconfig will detect an unconfigured router in the network and will launch the wizard for the basic settings. • • If you have not previously used any IP addresses in your network, select the option 'Make all settings automatically' in this wizard and confirm your selection with Finish in the next window.

After a few seconds, all of the computers in the network will be checked and are assigned a new IP address by the DHCP server as required. The computers also receive additional parameters such as the broadcast address, DNS server, default gateway, etc.
Operating modes and functions 75 tion's detour will be entered before the area code. The number is not sent out to the exchange until it has been completed in this manner. The LCR also requires the following information: • • • • A dialing prefix (area code) to determine which calls are possible for a detour. One or more network identification prefixes to determine the provider to be used for this prefix. The days of the week and holidays for which the entry is valid.
Operating modes and functions | EN For advanced users: systematic use of the LCR • • • • The first example has shown how connect charges can be reduced with only a few entries. If you would like to put the least-cost router to optimal use, detailed information is required with regard to the connect-charge structure of the call-by-call providers. Next, decide how these rates and rate zones can be best organized in the LANCOM Wireless IL-11 LCR table.

Enter each holiday with its full date (DD.MM.YYYY). e Check the internal clock of the unit (incl. the date), to ensure that the LCR activates the routing at the correct time (see also 'Time for the Selection' further below).
Operating modes and functions 79 c The current time is lost when the unit is switched off. Enter the number of a random remote station if you would like the device to establish a connection immediately upon being switched on, in order to synchronize the time with that of the ISDN network. Specify whether the remote station is digital (e.g. BBSs or Internet providers) or analog (telephone message or voice services). Please check the time after the first connection.
Operating modes and functions | EN LANCAPI. After restarting, the LANCOM CAPI Faxmodem will be available to your system. Under Windows 95 or Windows 98, it can be found under Start / Control Panel / Modems. 4.6.2 Faxing with the LANCOM CAPI Faxmodem Most major fax programs recognize the LANCOM CAPI Faxmodem automatically during installation and identify it as a 'Class 1' fax modem. Fax transmissions can thus be realized at speeds of up to 14,400 bps.
4.7.2 Operating modes and functions 81 • Subscriber numbers (MSN/terminal device selection numbers) The LANCAPI responds to incoming calls for these numbers. Multiple numbers are separated by semicolons. If no subscriber number is specified, the router will respond to all incoming calls. • Access to LANCAPI Here you can completely disable the LANCAPI functions for the interface, or enable it only for incoming or outgoing calls.

Configuring the LANCAPI client The configuration of the LANCAPI client is used to determine which LANCAPI servers will be used and how these will be checked. All parameters can remain at their default settings if you are using only one LANCOM Wireless IL-11 in your LAN as a LANCAPI server. a Start the LANCAPI client in the 'LANCOM' program group.
Operating modes and functions 83 EN | Configuring the LANCAPI server Two basic issues are important when configuring the LANCAPI server: • • What call numbers from the telephone network should LANCAPI respond to? Which of the computers in the local network should be able to access the telephone network via LANCAPI? Set the relevant parameters as follows: a Start LANconfig which can be found in the 'LANCOM' program group.
Operating modes and functions | EN 84 b Activate the LANCAPI server, or set it to permit outgoing calls only. In the latter case, the LANCAPI will not respond to incoming calls—to receive faxes, for example. Permitting outgoing calls only is useful if you do not have a specific call number available for the LANCAPI. c When the LANCAPI server is activated, enter the call numbers to which the LANCAPI should respond in the 'Number' field. You can enter several call numbers separated by semicolons.
Operating modes and functions 85 Switch to the 'availability' tab. Here you can determine how the LANCOM Wireless IL-11 should respond if a connection is to be established via the LANCAPI (incoming or outgoing) when both B channels are already busy (priority control). The available options are: • • • The connection cannot be established via the LANCAPI. A fax program using the LANCAPI will then probably attempt to send again at a later time.
Operating modes and functions EN • • 4.8 | You may use software which interacts directly with a CAPI (in this case, the LANCAPI) port.
