Using ACU
Note
When you upgrade your client adapter’s firmware using ACU, the Automatically Load New Firmware
When NDIS Driver Is Updated parameter on the Aironet Client Utility Preferences screen becomes
disabled (or unchecked) automatically to prevent the newly loaded firmware from being overwritten by
the driver. If you ever want to enable this parameter, you must recheck the check box.
To upgrade the firmware using ACU, follow the steps below.
Step 1
Use the computer’s web browser to access the following URL:
http://www.cisco.com/public/sw-center/sw-wireless.shtml
Step 2
Select Option #2: Aironet Wireless Software Display Tables.
Note
You can download software from the Software Selector tool instead of the display tables. To do
so, select Option #1: Aironet Wireless Software Selector, follow the instructions on the
screen, and go to

Select the latest firmware file for your specific client adapter type (such as CB or MPI).
Note
The firmware for PC, LM, and PCI cards is labeled PCMCIA-LMC-PCI, the firmware for mini
PCI cards is labeled mini PCI or MPI, and the firmware for PC-Cardbus cards is labeled CB.
Note
If your wireless network uses EAP authentication, access points to which your client adapter will
attempt to authenticate must use the following firmware versions or greater: 11.23T (340 and
350 series access points), Cisco IOS Release 12.2(4)JA (1100 series access points), or 11.54T
(1200 series access points).
Step 7
Read and accept the terms and conditions of the Software License Agreement.
Step 8
Select the firmware file again to download it.
Step 9
Save the file to a floppy disk or to your computer’s hard drive.
Step 10
Find the file using Windows Explorer, double-click it, and extract the image file to a folder.

you want the file to be placed, and click OK and Unzip. After the file is extracted, click OK to
close the screen.
