Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Linux
OL-1376-02
Chapter 7 Routine Procedures
Loading New Firmware
If your clients and infrastructure devices do not have matching IEEE 802.1x drafts, upgrade the firmware
in these devices to the same draft number. However, if your access points or bridges are using firmware
version 11.06 or later, you can use their Authenticator Configuration page to select the draft of the IEEE
802.1x protocol that they should use. To set the draft for your access points or bridges, follow the
instructions in the Release Notes for Cisco Aironet Access Points for firmware version 11.06.
You can access these Release Notes at this URL:
http://www.cisco.com/univercd/cc/td/doc/product/wireless/airo_350/350cards/linux/index.htm
Follow these steps to load new firmware.
Caution If a power failure occurs while you are loading new firmware, your client adapter can become
inoperable. If this occurs, follow the instructions in the “Obtaining Technical Assistance” section of the
Preface to contact TAC for assistance.
Step 1 Make sure the client adapter is installed in your computer and is operational.
Step 2 Use your web browser to access the following URL:
http://www.cisco.com/public/sw-center/sw-wireless.shtml
The wireless software page appears.
Step 3 In the Cisco Aironet Access Point, Wireless Bridge, Base Station, Workgroup Bridge and Wireless LAN
Client Adapter Firmware section, click the link for your client adapter.
Step 4 Identify the firmware you want to download.
Step 5 Download the firmware file to a directory on your computer’s hard drive.
Step 6 Use a Linux file extractor to extract the firmware files.
Step 7 Open ACU.
Step 8 From the Commands drop-down menu, select Load New Firmware. The File Selection window appears
(Figure 7-2).
