Introduction
This document describes system requirements, upgrade procedures, and caveats for the following release of Cisco Aironet client adapter software:
•Version 2.0.x of the Cisco Aironet client utilities for Linux
Release 2.0.x supports Cisco Aironet 350 Series mini PCI 100 mW radios and message integrity check (MIC) capabilities. A new installation shell script for PCI and PCMCIA with kernel PCMCIA enabled is included, including options for installing only the driver or utilities. Uninstall routines for both PCMCIA and PCI client adapters have also been added.
System Requirements
This release can be used with only Cisco Aironet 4500, 4800, 340, and 350 Series Wireless LAN Client Adapters (PC cards, LM cards, mini PCI cards, and PCI client adapters).
This release must be installed on a computer running a Linux operating system.
New and Changed Information
ACU release 2.0 contains the following new and changed information.
•Incorporated message integrity check (MIC) capability
•Supports 100 mW mini-PCI 350 series radios
•Added an install script for PCI client adapters
•Added install scripts for drivers and utilities
•Added new uninstall routines
Note Detailed information about new and changed information may found in the readme.txt file, which is included in the Linux-ACU-Driver-v2.0.tar.gz file
Installing ACU Release 2.0.x
You can install the driver and client utilities from the Cisco Aironet Wireless LAN Client Adapters Drivers and Utilities CD or at Cisco.com.
Note This procedure can be performed only by root users (those with administrative rights).
Note Cisco's Linux driver supports version 2.2.xx and 2.4.xx of the Linux kernel. To determine your kernel version, type uname -a and press Enter. The name of your computer and the Linux kernel version are displayed. For example, in Linux montecito 2.2.16-22#1 Wed Aug 8 164906 EDDT 2001 i686 unknown, montecito represents your computer's name, and 2.2.16-22 is the kernel version.
Caution If you are using a PCMCIA client adapter, do not insert it into the computer's PCMCIA slot until the driver has been loaded; otherwise, the computer could hang. The procedure indicates when the client adapter should be inserted.
Note If you are using a PCI client adapter, you can install it before you load the drivers.
Note These instructions are the same regardless of whether you are doing an initial install or upgrading from a previous version. If you are upgrading, your previous driver and client utilities are overwritten by the new ones.
Installation Shell Script Overview
The installation shell scripts are available for PCI and kernel PCMCIA configurations (such as Red Hat 7.2, which ships with kernel PCMCIA enabled). For these systems, execute sh kpciinstall as root. This program builds and installs the drivers and utilities for these configurations. If you have a PCI card only, the driver is properly installed and configured, eliminating the need to download card and socket services.
To remove the drivers and utilities installed by kpciinstall, execute sh kcpiinstall -R. After you have answered yes to the question asked, the drivers and the utilities are removed from your system. Other options are provided for installing the utilities or drivers only. Executing sh kpciinstall -id installs and builds the drivers, and sh kpciinstall -iu installs the utilities.
The options -ru and -rd remove the drivers or utilities respectively. For Red Hat 7.2 this is the kernel source rpm named kernel-source-2.4.7-10.i386.rpm. You can find this on CD 2 of the Red Hat 7.2 distribution in the directory Redhat/RPMS. Copy the file to a local directory or install it from the CD by entering rpm -iv kernel-source-2.4.7-10.i386.rpm. You must have the kernel source installed, and you can verify the installation by executing ls /usr/src. If the source is installed, you should see the message "linux-2.4 linux-2.4.7-10." If you do not see this message, the sources are not installed. If the kpciinstall script cannot locate the kernel source it prompts you to enter it. The prompt can appear if you compile the kernel sources. The installation of sources using Red Hat 7.2 places a link to the source in the /usr/src/Linux-2.4 directory. If the sources are installed, entering this directory in answer to the prompt causes the operation to proceed.
Installation Procedures
Installing or upgrading to version 2.0 is relatively simple. Bash shell scripts cwinstall for PCMCIA clients and kpciinstall for PCI clients are included in the download file to help install the driver and ACU. The script can accommodate a new installation or an upgrade. In the case of an upgrade, it is no longer necessary to remove any files from the previous version, cwinstall and kpciinstall accomplish that as part of the installation process.
If you are running a Red Hat system, you have three installation options, which are described in this section.
Note Because system-level changes are made, cwinstall and kpciinstall run properly only if executed as root.
Follow these steps to download and install the driver and ACU.

Step 13 Insert your client adapter into the computer and reboot (recommended) or restart Card and Socket Services. The driver loads automatically.
Step 14 Configure your client adapter. See the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Linux.
PCI Client Adapters
The installation shell script described in this section is for systems using a PCI client adapter and kernel PCMCIA. Red Hat version 7.2 ships with kernel PCMCIA enabled. The installation program builds and installs the drivers and utilities. The PCI installation program eliminates the need to download and run Card and Socket Services. Follow these steps to install the driver, ACU and other Linux utilities.
Step 1 Open a console screen and log in as root.
Step 2 Type sh kpciinstall and press Enter. The installation process begins and the following message appears:
Compiling driver module using source in /usr/src/linux-2.4.7-10Installing the utilities: acu bcard leapset leapscript leaploginInstalling Help Files ...Help Files Installed.Step 3 Type insmod airo to start the driver.
Step 4 Start the ACU.
Step 5 Configure your client adapter. See the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Linux.
Installation Instructions for Red Hat Systems
If you are using a Red Hat 7.1 or higher system, you have three installation options:
1. Use supplied driver binaries (recommended).
2. Using supplied patch and driver source, create your own modules; no kernel compilation is required.
3. Disable kernel PCMCIA support and install pcmcia-cs for PCMCIA support.
Option 1 is highly recommended. Options 2 and 3 require kernel sources and compilation tools. Follow the instructions in one of the following subsections for the option you choose.
Option 1 for Red Hat Systems
Option 1 is the easiest installation method; it needs no compilation. We recommend this method for systems installed with the workstation configuration.
Step 1 To select option 1, type 1 and press Enter.
Step 2 After an explanation appears, press Enter to continue.
Step 3 Your kernel information line appears, followed by a choice of default kernel configuration options. Here is an example kernel information line:
Linux leftbox.aironet.com 2.4.2-2 #1 Sun Apr 8 20:41:30 EDT 2001 i686 unknownIn this example, i686 means that this is a kernel for the i686 CPU family. Also note that the example does not contain smp or enterprise. From the list of available options displayed on the screen, the proper choice for this example would be h) kernel-2.4.2-i686.
Caution Be careful when selecting your option. Some configuration options look similar, and the system does not ensure that you select the correct one.
Type the letter of the configuration that matches your kernel and press Enter. The driver is now installed.
Step 4 Insert your PC card or PCI client adapter into the computer.
Step 5 Perform one of the following, depending on the type of client adapter you have:
•If you have a PC card, reboot your computer (recommended), or restart Card and Socket Services. The driver loads automatically.
•If you have a PCI client adapter, perform one of the following:
–If you have a distribution of Linux that uses linuxconf, such as Red Hat, use this utility to assign the driver to the PCI client adapter.
–If your distribution does not use linuxconf, manually edit one startup file to insert insmod airo.o to load the driver.
Note Follow the recommendations of your distribution regarding which startup file to modify and where to insert the command.
Step 6 Configure your client adapter. See the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Linux.
Option 2 for Red Hat Systems
Option 2 requires the presence of compilation tools but does not require the complete compilation/replacement of the installed kernel.
Caution You must use the kernel source in order to properly execute this procedure.
Step 1 To select option 2, type 2 and press Enter.
Step 2 After an explanation appears, press Enter to continue or Ctrl+C to exit.
Step 3 After another explanation appears, press Enter.
Step 4 Your kernel information line is displayed, followed by a choice of default kernel configuration options. Here is an example kernel information line:
Linux leftbox.aironet.com 2.4.2-2 #1 Sun Apr 8 20:41:30 EDT 2001 i686 unknownIn this example, i686 means that this is a kernel for the i686 CPU family. Also note that the example does not contain smp or enterprise. From the list of available options displayed on the screen, the proper choice for this example would be h) kernel-2.4.2-i686.
Type the letter of the configuration that matches your kernel and press Enter.
Caution Be careful when selecting your option. Some configuration options look similar, and the system does not ensure that you select the correct one.
Step 5 After an explanation appears on patching the kernel source, press Enter. The driver is now in place to be compiled, and the kernel source is patched.
Caution You should be using the kernel source as installed from Red Hat's CD-ROM. If the kernel is already in the patched state or has been modified, the patching process fails. If, however, the only change to the kernel is that it has used the Cisco Aironet patch previously, then you can successfully complete the procedure by pressing Enter twice at each series of prompts to skip the patch.
Note You might want to open another session so you can refer to the instructions on the screen.
Step 6 Type cd /usr/src/linux-2.4.2 and press Enter.
Step 7 Type make menuconfig and press Enter.
Step 8 In the menuconfig window, scroll down to Network device support and press Enter.
Step 9 Scroll down to Wireless LAN (non-hamradio) and press Enter.
Step 10 Scroll down to Cisco/Aironet 340/350 and type M (M indicates to make a module).
Step 11 Type E to exit.
Step 12 Scroll down to PCMCIA network device support and press Enter.
Step 13 Scroll down to Cisco/Aironet 340/350 and type M.
Step 14 Continue to select Exit and press Enter until the following message appears: "Do you wish to save your new kernel configuration?"
Step 15 Select Yes and press Enter.
Step 16 Type dep ; make modules ; make modules_install. The driver and client utilities are now installed.
Step 17 Insert your PCMCIA card into the computer.
Step 18 If you have a PCI client adapter, perform one of the following:
•If you have a distribution of Linux that uses linuxconf, such as Red Hat, use this utility to assign the driver to the PCI client adapter.
•If your distribution does not use linuxconf, manually edit one startup file to insert insmod airo.o to load the driver.
Note Follow the recommendations of your distribution regarding which startup file to modify and where to insert the command.
Step 19 Configure your client adapter. See the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Linux.
Option 3 for Red Hat Systems
Option 3 is the most advanced installation method because it requires a complete kernel rebuild and installation.
Caution You must use the kernel source in order to properly execute this procedure.
Note If you are not using a Red Hat 7.1 or higher system, but your distribution enables PCMCIA support in the kernel by default, you need to disable it by following the instructions in this section.
Step 1 To select option 3, type 3 and press Enter.
Step 2 Type cd /usr/src/linux-2.4.2 and press Enter.
Step 3 Type make menuconfig and press Enter.
Step 4 In the menuconfig window, scroll down to General setup and press Enter.
Step 5 Scroll down to PCMCIA/Cardbus support and press Enter.
Step 6 Continue to press the spacebar until the selector in front of the option is blank (does not contain an M or an *).
Step 7 Continue to select Exit and press Enter until the following message appears:
"Do you wish to save your new kernel configuration?"Step 8 Select Yes and press Enter.
Step 9 Rebuild your kernel.
Step 10 After the kernel is remade and reinstalled, reboot your computer.
Step 11 Go to Step 3 of the main upgrade procedure on page 3. This time select n when asked in Step 11 if you are using a Red Hat system with an unmodified kernel.
Installing the Driver or Utilities Only
Version 2.0 contains an installation script for PCI and kernel PCMCIA systems (such as Red Hat 7.2). The kpciinstall command followed by the -id option installs and builds only the drivers. The -iu option installs and builds only the utilities.
Verifying Installation
To verify that you have properly installed the appropriate driver and client utilities, type /opt/cisco/bin/acu & to open the ACU.
Note /opt/cisco/bin/ is the path where the ACU was installed.
If the installation was successful, the ACU main screen appears. Depending on how your wireless network is configured, your client adapter might or might not associate to an access point. The fact that you were able to launch the ACU verifies proper installation because it has found your client adapter's radio. You must configure the client adapter to communicate on your wireless network. See the Cisco Aironet Wireless LAN Client Adapter Installation and Configuration Guide for Linux for instructions on how to initially configure your client adapter.
If the installation was not successful, the ACU main screen does not appear. Instead, the message, "radio not found," appears at the Linux command prompt. See the Cisco Aironet Wireless LAN Client Adapter Installation and Configuration Guide for troubleshooting tips.
Note Additional information about this release is contained in the readme.txt file, which is included in the Linux-ACU-Driver-v2.0.tar.gz file.
Uninstalling the Driver and Client Utilities
If you experience difficulty while installing the driver, you might want to stop the installation procedure and start over. However, before you attempt to install the driver again, you must first remove any part of the driver that you might have already installed. You can remove the driver and client utilities manually, or by running an uninstall script.
Uninstalling Manually
To uninstall the driver and client utilities manually, enter the following at the command line (excluding the comment (#) lines).
#remove the utilities:rm /opt/cisco/bin/acu rm /opt/cisco/bin/bcard rm /opt/cisco/bin/leapset rm /opt/cisco/bin/leapscript rm /opt/cisco/bin/leaplogin rm /opt/cisco/ACU.PRFS# remove the utility subdirectory:rmdir /opt/cisco/bin# remove the help files:rm /opt/cisco/helpml.tar.gz rm /opt/cisco/helpml/*# remove the help files subdirectory:rmdir /opt/cisco/helpml# remove the main cisco directory:rmdir /opt/cisco# remmove the drivers (note: the card should not be in the system # when removing the drivers, otherwise the files might be in use)The location of the drivers can vary depending on the major kernel version in use (2.2 or 2.4) and whether or not the pcmcia-cs package was used. If your distribution supports the locate command (most do), the driver's locations can be determined by the output from locate airo and locate airo_cs.o. Use the rm command to remove the drivers.
For example, if locate airo.o returns:
# /ib/modules/2.2.16-25.uid32/pcmcia/airo.oyou would use:
rm /lib/modules/2.2.16-25.uid32/pcmcia/airo.oto remove the driver file. Use the same procedure to remove airo_cs.o.
If your system does not support the locate command, then you can use the find command as follows:
# find/-name airo.o and find/-name airo_cs.oUse the output from these commands as you would the output from the locate command discussed above. The driver and utilities are now removed from your system.
Running PCI Install and Uninstall Scripts
Version 2.0.x contains the new uninstall scripts for PCI card installations as shown in Table 1 below:

Open Caveats
•CSCin09572—System hangs occasionally when loading firmware or changing authentication type
This problem has occurred on an HP Omnibook XE3 running Red Hat version 7.0 with a mini-PCI card installed. When updating firmware, the system will sometimes hang regardless of security settings (None, Leap, or WEP). The problem has also occurred when changing authentication type from Leap to WEP.
The problem appears to occur only with the mini-PCI card. A PCM card performs properly in the same system.
Workaround—Reboot system if problem occurs.
