Step 13 Find the location of the new firmware in the Look in box.
Step 14 Click the firmware image file (*.img) so that it appears in the File name box at the bottom of the screen.
Step 15 Click the Open button. A progress bar appears while the selected image is loaded into the client adapter’s
Flash memory.
Step 16 Click OK when the “Firmware Upgrade Complete!” message appears. The OK button cannot be selected
until the process is complete or an error occurs. If an error occurs, refer to the “Error Messages” section in
Chapter 10.
Preventing the Driver from Upgrading the Firmware
The Automatically Load New Firmware When NDIS Driver Is Updated parameter on the Aironet Client
Utility Preferences screen affects the firmware that is bundled with the driver, not the firmware that is
included in the Install Wizard. This parameter controls whether the driver (whenever it loads) installs
the firmware with which it is bundled. (The driver loads each time you insert a client adapter or reboot
your computer.)
Note To complete this procedure, you must have used the Install Wizard to install ACU.
Note The Automatically Load New Firmware When NDIS Driver Is Updated parameter is functionally
equivalent to the Disable Firmware Checking parameter in the Install Wizard. The parameter that is set
last is the one that governs how the driver behaves. Refer to Chapter 3 for additional information.
Step 1 Open ACU.
Step 2 Click the Preferences icon or select Preferences from the Options drop-down menu. The Aironet Client
Utility Preferences screen appears (see Figure 9-5).
