Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Linux
OL-1376-02
Chapter 7 Routine Procedures
Selecting a Help Browser
Selecting a Help Browser
To view the ACU’s online help files, you must select an html browser to open when you click a Help
button in a screen that has online help. Follow these steps to select a help browser.
Step 1 From the Commands drop-down menu click Select help browser. An ACU window appears.
Step 2 Enter the path to your browser and click OK.
When you click on a screen’s help button, the browser you specified opens the help page for that screen.
Loading New Firmware
Your client adapter’s firmware is in the adapter’s Flash memory, which allows it to be easily updated.
Your adapter’s firmware version is shown on the Status screen. See the “Viewing the Current Status of
Your Client Adap ter” section on page 6-2 for instructions on accessing this screen.
You can find the latest firmware version at http://www.cisco.com/public/sw-center/sw-wireless.shtml.
Note Firmware files are prepared in self-extracting executable files that Linux cannot automatically extract.
You need a Linux file extractor application such as unzip in order to extract the firmware image file.
Follow the instructions in this section to load the new firmware into your client adapter.
Matching the Protocol Drafts for EAP Authentication
If you use Network-EAP authentication on your wireless network, your client devices and infrastructure
devices (access points and bridges) must use the same IEEE 802.1x protocol draft. Client firmware
release 4.25.23 supports draft 10 of the IEEE 802.1x protocol standard. Therefore, if your wireless
network’s client devices use this firmware standard, the access points to which they will associate must
be configured to also use Draft 10. Table 7-1 lists firmware versions for Cisco Aironet products and the
drafts to which they comply.
