When a section is marked as (OPTIONAL), don’t do it immediately but only at the end of the lab if you still have time. INSTALLING WIRELESS LAN ADAPTER CARDS Installation of the PCI wireless adapter in the workstation was already done by your instructor to avoid cabling and screwdrivers injuries issues Reference intranet website http://kheops.unice.fr/~frati/ ... (répertoires et outils spécifiques _TOOLS, _DRIVERS, ...) INSTALLING AIRONET CLIENT/DESKTOP UTILITY (ACU OR ADU), PREVIOUS VERSION OF THE SOFTWARE Objective The student will learn the procedures for installing the Aironet Client/Desktop Utility (ACU/ADU), the software that manages the Cisco Aironet wireless network card. Also, the student will configure, select, and manage profiles that predefine the WLAN connections. Scenario Install and configure the ACU/ADU and additional software options to allow a user to configure, manage, and monitor wireless connections. Two client utilities are available for use with the client adapters: Aironet Desktop Utility (ADU) and Aironet System Tray Utility (ASTU). These utilities are optional applications that interact with the client adapter's radio to adjust settings and display information. ADU enables you to create configuration profiles for your client adapter and perform user-level diagnostics. Because ADU performs a variety of functions, it is documented by function throughout this manual. ASTU, which is accessible from an icon in the Windows system tray, provides a small subset of the features available through ADU. Specifically, it enables you to view status information about your client adapter and perform basic tasks. Preparation This lab will require the following materials: • Desktop PC • Appropriate wireless client adapter card • One Cisco Aironet Client Adapter Network Interface Card (CB21 or PI21) drivers are located approximately in http://iutsa.unice.fr/~frati/_DRIVERS/Cisco/Cisco%20Aironet%20CB21AG%20and%20PI21AG%29/ • Cisco Aironet Client/Desktop Utility installer (directory _DRIVERS or CD) • two other Ethernet card (named IUT and TP) • The instructor had already setup an access point in order to simulate an Home, an Office and a public network like in an airport respectively called: o « Office » network with SSID: InTheOffice o « Home » network with SSID: AtHome o « Airport » represents any public network like in an airport : AirportHotSpot Note: Keep in mind that SSIDs are case sensitive... RESOURCES http://www.cisco.com/en/US/products/hw/wireless/ps4555/products_installation_and_configuration_g uide_book09186a0080184b6e.html for Official Cisco Web site See your instructor for: http://kheops.unice.fr/~frati/Wireless/TP/ for this kind of documents http://kheops.unice.fr/~frati/_TOOLS/ for networking and performance tools http://kheops.unice.fr/~frati/_DRIVERS/ for Cisco, NetGear and 3Com softwares, drivers, docs, ... STEP 1 CONFIGURE WINDOWS TO USE THE ADU (INSTEAD OF WZC) Note When reading ACU, keep in mind this also means ADU: Aironet Desktop Utility as ACU was the previous name of the utility To configure the client adapter through ACU instead of through Windows XP, follow the steps below: a. Double-click My Computer, Control Panel, and Network Connections. Click Start>Control Panel then double-click Network Connections. For Windows XP, click Start>My Computer>Control Panel>System. See your instructor for instructions for other operating systems. b. Right-click Wireless Network Connection and click Properties. c. Select the Wireless Networks tab. d. Deselect the Use Windows to configure my wireless network settings check box (this is where you disable the built-in Windows Zero Config utility of Windows.). e. Follow the instructions in the "Installing ACU" section to install ACU. Note Check in Windows services what is the status of the « Windows Zero Config » service. STEP 2 INSTALL THE AIRONET CLIENT UTILIT IES (ACU) OR THE LATEST AIRONET DESKTOP UTILITIES (ADU) Prior to installing ADU software and card drivers, check that the client adapter has been physically already installed into the laptop or desktop computer by the instructor. After the appropriate driver is installed for the computer's operating system and for the client adapter type, follow the steps below to install the Aironet Client Utility (ACU). Note: If EAP-TLS, EAP-MD5, PEAP, or EAP-SIM authentication is going to be used on a computer runningWindows 2000, Service Pack 3 for Windows 2000 and the Windows 2000 Wireless 802.1X hot fixmust be installed before installing ACU. If a version of ACU prior to 4.13 is installed on the computer, uninstall it; then follow the steps to install the latest version. Note The most recent version of the ACU can be obtained through the official Software Center on the Cisco Connection Online (CCO) or the unofficial http://kheops.unice.fr/~frati/_DRIVERS/ See your instructor for instructions for which release of software to use and what options to select during installation (e.g. select installation of the Site Survey Utility). WinClient-802.11a-b-g-Ins-Wizard-v35.exe should be used by default. Note To install or use the client utilities on Windows NT or Windows 2000 systems, a user must log on to the system as a user with administrative privileges. The utilities do not install or operate correctly for users not logged in with administrative rights. Note The old ACU versus the latest ADU display. Both are deployed today in the field. When the computer reboots, Windows may recognize that a new hardware has been installed. a. Click Cancel on the Windows Found New Hardware Wizard to continue. b. Navigate to the installation file for the client adapter. This file can be found either on the CD that came in the package with the CD or on a network server like Kheops as if this file was downloaded from Cisco.com. Note It is usually recommended to download the latest release as the CD was printed when the hardware shipped: modifications/bug-fixings have probably happened since. For this lab, ask the instructor for the appropriate relase to be used (probably not from CD-ROM but the _DRIVERS directory on Kheops). c. Double click the approprioate executable file to begin installation. d. From the available Setup types, select the first option: Install Client Utilities and Driver. This option will install all of the necessary files for both the client adapter and the desktop utility. Click Next to continue. e. Now there is a prompt to accept a system reboot after installation completes. Click Yes to continue installation. Clicking No will cause installation to abort. f. The default settings can be accepted for the destination folder. Remember to reboot the computer when installation has completed. Note The Site Survey option is to be installed too. You'll use it later on. Note: Installation asks you if you want to use Windows (WZC) or ADU for managing your wireless adapter. Select “Third party tool” you can change it later-on. Note: Installation asks you if you want the small icon in the “system tray” (barre du bas d’e votre écran windows). It is called ASTU and use for a quick access to your wireless card configuration. Reboot is needed to redetect hardware changes and apply appropriate new installed drivers. STEP 3 COMPLETE THE DRIVER INSTALLATION AFTER REBOOT a. Double-click My Computer, Control Panel, and Network and Dial-up Connections. b. Right-click the Local Area Connection corresponding to your Wireless Adapter. c. Click Properties, Internet Protocol (TCP/IP), and Properties. d. Click Use the following IP address and enter the IP address, subnet mask, and default gateway address of the computer which can be obtained from the instructor (try DHCP, if you do not get a lease, pick a random address in the range 192.168.4.0/24). Click OK. e. In the Local Area Connection Properties window, click OK. f. If prompted to restart the computer, click Yes. g. The driver installation is complete. STEP 4 VERIFY THE TCP/IP SETTINGS a. Select Start > Run and enter the following: b. On Win2000 or XP, enter cmd to bring up the command prompt. While at the command prompt, type in ipconfig /all to verify the IP settings. What is your IP addressing configuration ? IP@: Netmask: Default gateway: STEP 5 RUNNING ADU To open the ADU double-click the desktop icon or navigate to the program shortcut from the Start button: Start>Programs>Cisco Aironet>Aironet Desktop Utility. Alternately, the System Tray icon can be used to launch the desktop utility (via ASTU). The tabbed interface of the ADU allows access to each of the necessary tasks to configure and monitor the client adapter. a. Click the Advanced button to view detailed setting information for the card. The Advanced Status tab can provide useful information about the current SSID as well as association information for the card. Click OK to close the window and return. Write down what's in front of the following fields and explain the current status displayed: Channel: Frequency: Channel Set: STEP 6 USING THE PRO FILE MANAGEMENT Password if needed WEP40 in HEXADECIMAL: 123345ABCDE Password if needed WEP128 in HEXADECIMAL: 12334567890123345678901233456 The Profile Management tab allows the creation, modification, removal or activation of client adapter profiles. Each profile can contain a unique set of authentication and encryption settings. When installed, your client software is already configured with a built-in profile. When starting the ADU, is there an already preselected profile ? What are the name and properties of this built-in profile ? What is the default behaviour when no SSID is provided in the profile (3 SSID fields empty) ? Note The Profile manager will allow you to create several profile and activate them. A profile contains up to three SSIDs. Starting from now, you'll define several profiles in order to simulate real life use and situations. Imagine you have a wireless connection in the Office when working during the day with your laptop. When back to your Home, you also have a CrétinBox working as an Access Point too for your residential gateway. Then, when you travel a lot, while waiting in public places, you want to be able to connect to public hotspots like the one you'll find at the Airport. So, you'll configure enough profiles and SSIDs in each profile in this aim and have them being automagically selected as you are moving from one place to another. First, follow the steps below to create a new profile. a. Select the Profile Management tab. b. Click New and enter the name for the first new Profile Name named “Office” corresponding to the InTheOffice SSID as described below. Note To use the default values, click OK. The profile is added to the list of profiles on the Profile Manager screen. d. Check you have configured the Client name and SSID for the Office profile as directed by the instructor in order to connect to the appropriate AP. Remember that configuring your Profile manages your level one (physical/802.11) connectivity but does not manage your level three (network/IP) connectivity. e. Click OK to save your profile. Can you active several profiles at a time? When would you consider entering multiple Network Names instead of a single one ? f. Create additional profiles named “Home” with SSID « AtHome » and “Airport” with « any » allowed SSID. What is specific to the SSID « any » ? What would it allow you ? Describe the steps to create and test it. Compare it to the Default profile. STEP 7 SELECTING PRO FILE ACTIVATION Now you have created several profiles, you'll manually select the one you're interested in, one at a time. Follow the steps below to specify the profile that the client adapter is to use. a. Open ADU; click the Profile Management tab. b. Now select the Office Profile c. Click Activate to save the selection. d. The client adapter starts using a profile based on the option selected above. Note Use double-click for selection and activation “on the fly”. What are the benefits of being able to define several profiles ? Why is this better to use three different profiles with one SSID in each rather than creating one single profile including all the three SSID ? So, is it possible using only one of the previous three profiles to connect all networks represented by all the three SSID ? Note Other tabs of the ADU will be covered later in the upcoming sessions: browse through them but be patient... Note If the client adapter cannot associate to an AP or looses association while using the selected profile, the adapter does not attempt to associate using another profile. To associate, a different profile must be manually selected. But have a look on the next paragraph... STEP 8 USING THE ORDER PROFILES BUTTON Clicking the “order Profiles” button in the Profile Management tab of the ADU causes the client adapter's driver to automatically select a profile from the ordered list of profiles that were set up to be included in auto profile selection. Configured profiles can be tried in a specified order. When would you consider « using » or « not using » this feature: describe one scenario for each. STEP 9 USING THE AIR ONET CLIENT MONITOR (AKA ACM) OR AIRONET SYSTEM TRAY UTILITY (AKA ASTU) ACM/ASTU is an optional application that provides a small subset of the features available through ACU/ADU. Specifically, it enables you to access status information about your client adapter and perform basic tasks. ACM/ASTU is accessible from an icon in the Windows system tray, making it easily accessible and convenient to use. The profile can also be quickly switched through the system tray using right-click on the ASTU. a. Right click on the ASTU icon and go to Select Profile, then choose the Home profile. b. The client will now associate to the respective AP. Observe the ASTU icon and especially the colors it takes. c. Now select the Airport profile. Observe the ASTU icon turn gray. d. Finally, re-select the Office profile to connect to the first AP. The ASTU icon should turn green. When green, does it mean you have a level 2 (802.11) or level 3 (IP address) set up ? The client adapter status and updates the icon every 2 seconds Here below are the available colors. Report to documentation to fill up the arry with appropriate color/description association. Green, Yellow, Red, White, Grey, Light grey Icon color Description __________ The client adapter's radio is turned off. __________ The client adapter is not associated to an AP. __________ The client adapter is associated to an AP, but the user is not authenticated. __________ The client adapter is associated to an AP, and the link quality is excellent or good. __________ The client adapter is associated to an AP, and the link quality is fair. __________ The client adapter is associated to an AP, and the link quality is poor. STEP 11 IMPORTING AN D EXPORTING PROFILES To understand the benefits of this feature, first imagine you are the network administrator of a fleet of hundred sales road-warriors using a wifi laptop each. This section provides instructions for importing and exporting profiles. You may want to use the import/export feature for the following reasons: • To back up profiles before uninstalling the client adapter driver or changing radio types • To set up your computer with a profile from another computer • To export one of your profiles and use it to set up additional computers Follow the steps in the corresponding section below to import or export profiles with the group (binôme) next to your table. EXPORTING A PROFILE a. Insert a blank floppy or USB disk into your computer's, if you wish to export a profile. Or save the file to the PC hard disk and have it publicly available for other groups. b. Open ACU; select Profile Management tab c. From the Profile Management list, select the profile that you want to export, e.g. « Net405px » . d. Click Export. The Save Profile As screen appears. The default filename is ProfileName.prf, where ProfileName is the name of the selected profile, and the default directory is the directory in which ACU was installed. e. If you want to change the profile name, enter a new name in the File name edit box. f. Select a different directory (for example, your computer's floppy or usb disk drive or a location on the network) from the Save in drop-down box. g. Click Save. The profile is exported to the specified location. h. Exchange your respective profiles with your neigbourgh in front of you. IMPORTING A PROFILE a. If the profile that you want to import is on a floppy ou USB disk, insert it into your computer's. b. Open ACU; select Profile Management tab c. Click Import. The Import Profile screen appears. d. Find the directory where the profile is located. e. Click the profile so it appears in the File name box at the bottom of the Import Profile screen. f. Click Open. The imported profile appears in the list of profiles on the Profile Manager screen. In real life situation, exporting from one side and exporting to the other side is not enough to set up a level 3 network connectivity. What else is needed to gain an IP network access ? STEP 12 SCANNING FOR AVAILABLE NETWORKS USING ADU The Profile Management tab also includes a Scan button that displays Available APs and Ad Hoc Networks. Those network names listed with a key icon demonstrate that the network is secured. If no key is displayed, the network is not secured and will likely accept guest associations. Highlight a network name (Hotspot-Unice for instance...) and click the Activate button to connect to an available network. If no configuration profile exists for that network, the Network Configuration Settings window opens to the General tab. Fill in the network name and click OK to create the configuration profile for that network. Click the Scan button and write down what are the available Infrastructure and Ad Hoc networks (or insert a screenshot) STEP 13 SCANNING FOR AVAILABLE NETWORKS USING WZC Enable the Windows Zero Config instead of the ADU. Rescan for SSID discovery using WZC and check that: - you can’t find anymore the InTheOffice SSID and any other hidden SSID why ? - you can’t make a difference between one UniceHotspot AP and Windows does not let you know how many AP are available Which one of WZC or Cisco ADU gives you more information about your wireless accesses ? STEP 14 MANAGING THE WIRELESS ADAPTER USING THE NATIVE WINDOW S ZERO CONFIG WIZARD AND SERVICE Or « how to use Another Application To Configure My Wireless Settings » This option allows another application (not the ADU/ACU) to configure the client adapter, like a multi-vendor piece of software or a snap-in directly included in the OS itself. Examples of such applications include Windows XP Zero Configuration Wizard and Boingo. You can manage your wireless adaptor using one software or the other but not the two in the same time: Windows Zero Config: this windows service is implemented as a wizard that detects Wireless networks (using the Wireless Provisioning Services included in Windows XP SP2 or Windows2003Svr SP1) and proposes you for a connection using windows built-in driver. ACU/ADU software: the software and driver provided by your wireless hardware vendor. In one option or the other, you have benefits and drawbacks and you need to be aware of both in order to make your decision. HOW TO ACTIVATE/DEAC TIVATE THE WZC SERVI CE You must tick this option « Utiliser Windows pour configurer mon réseau sans fil » if you are configuring your card through Windows XP Windows Zero Config service (but do not want to use ACU's configuration and diagnostic tools). Note Be careful, when you have several wireless adapters, activating the WZC activates it for all wireless adapters. Can you access the same of configuration features as with the Cisco specific software configuration client ? Do you think all vendor's cards are supported ? STEP 18 UNINSTALL THE AIRONE T CLIENT UTILITIES Attention, please: Usually, this part of the lab (clearing the configuration) has to be done if there are two groups of TP, one after the other relaying on the same lab machines. See your instructor before any action. a. Uninstall the Client Utilities b. Close any Windows programs that are running. c. Open Windows Control Panel and the « Add/Remove Program » wizard. Then select the softwares to be removed: the Cisco ADU and ASTU. d. Reboot.
