2 System Requirements System Requirements You will need the following in order to install and use ACU release : A Cisco Aironet 340, 350, or 4800 series PC card, LM card, PCI card, or mini PCI card A computer running Windows 95, 98, NT, 2000, Me, or XP A display with a minimum resolution of 800 x 600 pixels PCM/LMC/PCI card driver version or greater and PCM/LMC/PCI card firmware version or greater (or mini PCI card driver version or greater and mini PCI card firmware version or greater) To benefit from the latest security features, access point firmware version 11.10T or greater Installing or Upgrading to a New ACU Release This section describes how to initially install or upgrade to the ACU release. If ACU has never been installed on your computer or if ACU version 4.13 or greater is currently installed, follow the instructions in the Installation/Upgrade Procedure section below. If a version of ACU prior to 4.13 is installed on your computer, follow the instructions in the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows to uninstall it; then follow the steps in the Installation/Upgrade Procedure section below to install version Determining the Current ACU Version To determine the version of ACU that your client adapter is currently using, open ACU; then click the About icon or select the About Aironet Client Utility option from the Help drop-down menu. The About Aironet Client Utility screen appears and displays the current version of ACU. Installation/Upgrade Procedure Follow the steps below to install/upgrade ACU on Windows 95, 98, NT, 2000, Me, or XP. If you downloaded a Windows bundled file from Cisco.com and extracted its software files to a folder, close any Windows programs that are running and follow the instructions below beginning with Step 9. The file referred to in this step is the ACU file that was extracted from the bundle. Step 1 Step 2 Step 3 Step 4 Close any Windows programs that are running. Use the computer s web browser to access the following URL: Locate the section for client adapter drivers and utilities. Click the link for individual Windows files. 2

3 Installing or Upgrading to a New ACU Release Step 5 Step 6 Step 7 Step 8 Step 9 Step 10 Step 11 Step 12 Select the latest ACU file. Read and accept the terms and conditions of the Software License Agreement. Select the ACU file to download it. Save the file to your computer s hard drive. Locate the file using Windows Explorer, double-click it, and extract its files to a folder. Select Start > Run, enter or browse to the path where you extracted the files (for example, C:\temp\setup.exe), and click OK. The Aironet Client Utility Setup screen and the InstallShield Wizard appear. When the Welcome screen appears, click Next. In the Select Options screen, select as many of the following options as desired and click Next: Option LEAP Allow Saved LEAP User Name and Password Create ACU Icon on your Desktop Allow Non-Administrator Users to use ACU to modify profiles Description Enables you to create a profile in ACU that uses LEAP authentication. If this option is not selected now and you later want to use LEAP, you must run this installation program again, select Modify, and select this option. Default: Selected If you select LEAP on a Windows 95, 98, or 98 SE device, Microsoft hot fixes are installed during ACU installation to fix two problems related to the use of LEAP. If you select LEAP on a Windows XP device, you cannot use the Windows XP fast user switching feature. Enables you to create a profile in ACU that uses a saved (rather than temporary) username and password for LEAP authentication. When such a profile is used, the saved username and password are used to start the LEAP authentication process, and you are not prompted to enter them. Default: Selected This option is available only if the LEAP option is selected. Causes the installation program to add an ACU icon to your computer s desktop to provide quick access to the utility. Default: Deselected Enables users without administrative rights to modify profiles in ACU on computers running Windows NT, 2000, or XP. Default: Selected This option is not available for Windows 95, 98, and Me because these versions of Windows do not support different classes of users. 3

4 New and Changed Information Step 13 Step 14 Step 15 In the Choose Destination Location screen, perform one of the following: If you want the ACU program files to be installed in the default location (C:\Program Files, provided C:\Program Files is the default Windows program file folder), click Next. If you want to specify a different destination location for the ACU program files, click Browse, select a location, and click Next. In the Select Program Folder screen, specify a program folder name for ACU by selecting from the list of existing folders (the default name is Cisco Aironet) or entering a new folder name; then click Next. A status screen displays the progress of the installation. Then one of two Setup Complete screens appears, depending on whether Windows needs to be restarted to complete the installation. Perform one of the following: If your computer does not need to be rebooted, select either of the following options and click Finish: Option View the README.TXT file Launch the Aironet Client Utility Description Opens a read-me file containing information about ACU. Opens ACU so you can configure your client adapter. If your computer needs to be rebooted, select Yes, I want to restart my computer now or No, I will restart my computer later and click Finish. If you are prompted to reboot your computer, Cisco recommends that you select the Yes, I want to restart my computer now option. The client utility installation is complete. Using ACU For instructions on using ACU (to create profiles, configure the client adapter, use the diagnostic tools, etc.) with Cisco Aironet 340 and 350 Series Wireless LAN Client Adapters, access the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows at the following URL: New and Changed Information IP Address of Client Now Displayed The client s IP address is now displayed on the ACU Status screen. The IP Address field is located in the middle of the screen. 4

5 New and Changed Information Ability to Periodically Scan for a Better Access Point Added to ACU The Periodically Scan For A Better Access Point parameter has been added to the ACU RF Network screen. If you enable this feature (by selecting the checkbox), the client looks for a better access point if its signal strength becomes low and switches associations if it finds one. This parameter is available only if your client adapter is using PCM/LMC/PCI card firmware version or greater (or mini PCI card firmware version or greater). Ability to Select Clear Channel Assessment (CCA) Added to ACU The Clear Channel Assessment parameter has been added to the ACU RF Network screen. This feature allows you to select the method that determines whether the channel on which your client adapter will operate is clear prior to the transmission of data. The following methods are available from the parameter s drop-down list: Firmware Default (XXX) - The CCA mechanism reports that the channel is busy based on the default value of the client adapter s firmware. The firmware s CCA default value is shown in parentheses. For example, the CCA default value for PCM/LMC/PCI card firmware is Car/Cor, and the default value for mini PCI card firmware is ED. Carrier/Correlation (Car/Cor) - The CCA mechanism reports that the channel is busy upon detection of a direct-sequence spread spectrum (DSSS) signal. This signal may be above or below the ED threshold. Energy Detect (ED) - The CCA mechanism reports that the channel is busy upon detection of any energy above the ED threshold. ED or Car/Cor - The CCA mechanism reports that the channel is busy upon detection of a DSSS signal or any energy above the ED threshold. This parameter is available only if your client adapter is using PCM/LMC/PCI card firmware version or greater (or mini PCI card firmware version or greater). Ability to Reauthenticate after LEAP Credentials Expire If the LEAP credentials (username and password) for your current profile expire or become invalid, you are notified and prompted to enter your new username and password. The client adapter should authenticate using your new credentials. If the current profile uses saved LEAP credentials, you must save your new username and password on the LEAP Settings screen in ACU. 5

6 Caveats If your computer is running Windows NT, 2000, or XP and you change your Windows password using the standard Windows Change Password function, the client updates the LEAP password automatically and maintains its connection to the access point if the current profile uses the Windows username and password. If your computer is running Windows 95, 98, or Me and you change your Windows password, the client loses association from the access point, and you are prompted to enter your new credentials. Antenna Identification Change in ACU The Antenna Mode (Receive) and Antenna Mode (Transmit) parameters on the ACU Advanced (Infrastructure) and Advanced (Ad Hoc) screens no longer provide Right Antenna Only and Left Antenna Only options. Instead, these options are listed as Primary Antenna Only and Secondary Antenna Only, respectively. This new terminology is also displayed on the ACU Status screen. The Antenna Selection field shows the receive and transmit antenna settings as Diversity, Primary Only, or Secondary Only. Caveats This section describes resolved and open caveats for Windows ACU release Resolved Caveats The following caveats are resolved by Windows ACU release LEAP Login Screen Displays Last Successful Username On the LEAP login screen, the username used for the last successful login always appears in the User Name field (CSCdw71443). This caveat is resolved in ACU release for Windows NT, 2000, and XP. The User Name field is now blank when the login screen appears if you specify Do not display last user name on the network login screen. ACU Prompts for LEAP Login Although Client Has Already Auto-Connected ACU prompts for your LEAP login although the client has already auto-connected using a saved username and password and Novell Client is installed. When you enter the password, the client fails to authenticate. If you select Cancel, the client authenticates (CSCdw42847). This caveat is resolved in ACU release

7 Caveats Client Passes Only IPX Frames and Does Not Try Frames The client passes only IPX frames and does not try frames if the IPX frame type is set to auto detection. This problem is caused by the IPX stack, which starts the frame type auto detection at system startup, before LEAP authentication begins and a network connection is established. When it fails, it defaults to the frame type (CSCdu87664). This caveat is resolved for Windows 2000 and XP in ACU release This caveat will be resolved for other Windows operating systems in a future release. ACU Default State Prevents the Client from Being Configured Through Windows XP If you configure your client adapter using Windows XP and then install ACU and leave it in its default state (Allow Windows To Configure My Wireless Network Settings deselected), the client is no longer configurable through Windows XP (CSCdv81972). This caveat is resolved in ACU release Client Becomes Locked Out When the LEAP Password Is Changed If a client authenticates to an ACS server using LEAP and the password on the server is changed during the session, the LEAP session times out, and the client uses its cached credentials to reauthenticate. However, since the password is now set differently on the server, the reauthentication attempt fails. The client is not aware of the problem and continually tries to reauthenticate, resulting in multiple failed attempts and causing the user to be locked out of his or her account (CSCdw29118). This caveat is resolved in ACU release but relies on PCM/LMC/PCI card driver release and PCM/LMC/PCI card firmware release (or mini PCI card driver release and mini PCI card firmware release ). See the Ability to Reauthenticate after LEAP Credentials Expire section on page 5 for information on how this caveat has been resolved. Channel Cannot Be Selected for Ad Hoc Profile When you create a profile using ad hoc mode, you cannot select a radio channel. You must back out of the profile and then edit it again in order to be able to select a channel (CSCdv85467). This caveat is resolved in ACU release Disallowing Non-Administrative Users to Modify Profiles Does Not Work in ACU Installation Program If you deselect the Allow Non-Administrator Users to use ACU to modify profiles checkbox during ACU installation, non-administrative users are nevertheless able to modify profiles (CSCdw13089). However, this same checkbox on the Aironet Client Preferences screen does allow you to deny modification privileges to non-administrative users. This caveat is resolved in ACU release ACU s Linktest and Site Survey Screens Are Not Set to Defaults ACU s Linktest and Site Survey screens do not open with their default values displayed. For example, when you open the Linktest screen, the Number of Packets field is set to 100 although the default value is 4 (CSCdw44793). This caveat is resolved in ACU release

8 Caveats ACU Icons Do Not Appear on Windows 95 On Windows 95, icons do not appear on the Aironet Client Utility screen (CSCdv85564). To resolve this issue, select ACU options through the Commands, Options, or Help drop-down menus or upgrade your version of Internet Explorer to enable the icons to appear. Open Caveats The following are known problems for Windows ACU release Some Laptops Cannot Enter Suspend or Hibernation with ACU Installed If your laptop is running Windows 98 or Me and has a mini PCI card and ACU version installed, the unit may not be able to enter suspend or hibernation mode using the timer (CSCdx34586). IP Address of Access Point Is Not Displayed in ACU The status bar at the bottom of the Aironet Client Utility screen displays the MAC address of the associated access point but not the IP address (CSCin07387). Profile Manager Accepts Blank Profiles ACU allows you to create, edit, rename, delete, import, and export blank profiles, which are created by entering spaces for the profile name (CSCin06561). ACU Crashes When the Site Survey or Link Test Is Running and You Remove the Client Adapter If you click the Start button on the Site Survey or Linktest screen and then remove the client adapter, ACU crashes (CSCin07193). ACU Crashes Intermittently When You Save Profile Changes ACU crashes intermittently when you save changes to a profile (CSCin07234). ACU Crashes When You Import an Invalid Profile If you attempt to import an invalid profile (for example, a text file), a message appears indicating that the profile is corrupt and will not be imported. Then ACU crashes (CSCin06823). Canceling Profile Manager Repeatedly Generates an Error If you repeatedly open and cancel Profile Manager, the following error message appears: Windgs.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log is being created (CSCdx05038). 8

9 Troubleshooting Minimum Value for Site Survey Packet Size Is Incorrect The slider for the Packet Size parameter on the Site Survey Active Mode Setup screen starts at 30, but the utility accepts values as low as 1 (CSCin07209). ACU Does Not Recognize Removal of One Radio Card Type and Insertion of Another If you start ACU while a client adapter of one radio type is inserted (such as a 340 series PC card) and then eject the card and replace it with a card of another radio type (such as a 350 series PC card), ACU indicates that Your Wireless LAN Adapter is not inserted until ACU is shut down and restarted (CSCdv67623). LEAP Authentication Continues after LEAP Support Is Disabled If a profile that uses LEAP with a saved username and password is selected and then LEAP is disabled through the ACU installation program (by selecting Modify and deselecting the LEAP checkbox), the client adapter continues to LEAP authenticate after the system reboots (CSCdv64355). In fact, the client authenticates before login and remains associated after logoff. Profile Manager and Status Screens Do Not Fit on 640 x 480 Displays Some of the buttons on ACU s Profile Manager and Status screens are not visible when viewed on displays with a 640 x 480 resolution. Cisco recommends using a display with a minimum resolution of 800 x 600.
