Figure 5-2. Type the IP address, browse for the file bridge.rom and download
The Firmware Download procedure will be completed successfully if a message in the
right bottom corner appears indicating “Firmware download has been completed”. If you
receive the message “TimedOut”, in the right bottom corner, during the firmware down-
load procedure, you need to check if the Access Point is powered on and if it has a valid
IP address. In order to check the validity of the IP address you must ping the Access
Point.
If you receive the message “Flash Programming in progress” during the firmware down-
load procedure you shouldn’t power off the Access Point. In order to close the
application press the "Exit" button.
Note: If the download procedure has not been completed successfully you must try
again but before starting the download you need to confirm that you are using
the correct firmware file .

5.2 Using the USB
Port
Note: This procedure requires the use of the DFU Configuration Utility which can be
used only through the USB port. When you connect the card to the USB port for
the very first time, the operating system will ask for the driver for the card.
Please locate the driver into your CD. At this time, only a driver for MS Windows
98 is available. After you have completed the installation of the driver, you can
use the DFU Configuration Utility.
In order to upgrade the firmware of the AP through the USB port, you must use
the DFU Configuration Utility.
First of all you have to plug the USB cable and then open the DFU.exe application which
you will find into the “Utilities” folder of your CD.
In the main window of the DFU Configuration Utility (Figure 5-5), select the file xxxx.rom,
by pressing the “three dots” button. Finally press the “Download” button.
