Following this forum and many user discussions related to wifi shield firmware update, we decided to perform the update ourselves. We followed the procedure from http://arduino.cc/en/Hacking/WiFiShieldFirmwareUpgrading. It was straight forward and we did this successfully. Passing on the information, we have documented the entire update process with screenshots and output.
Hope this helps
i tried the fw update, i got this message: AtlibUsdDfu.dll not found. See attached image. How can i go on?

Sounds like USB driver needs to be updates.
From Atmel support:
Follow the instructions detailed in the install.txt file in C:\Program Files\ATMEL\FLIP X.X.X\info Directory.
Please, read the sections :
NEW USB DRIVER INSTALLATION for Windows 2000 or
NEW USB DRIVER INSTALLATION for Windows XP
Actually I use Win 8, so the offered upgrades for win2000 or xp does not solve my problem. Unfortunately I do not know how to proceed:(.
The saga is going on. Finally I turned to my old PC, running WinXP, and updated the Wifi Shield firmware. I got back the same screenshots as given in the process docs. Since I do nor have FTDI cable, I could not check its success except that the screenshots were OK for both files.
Look at what happened with my project on UNO R3 and wifi shield config:
Using IDE 1.0.4, sketch is running well, wifi connection and HTTP requests are OK. Super!
Change to IDE 1.0.5, sketch is uploaded, wifi connection established, but no data traffic , I can not see any HTTP request coming out from the box. What is observable, that the blue data led of the wifi shield is NOT blinking when using IDE 1.0.5. :0
My Wifi shield does not work with IDE 1.0.5
Firmware update is problematic with Win8, I could only perform with WinXP.
Are there any idea or proposal which can help me?
One more suggestion.
Review the Wifi firmware update page not_found. Note there is a USB Driver for AT32UC3 microcontroller on Windows listed in Tools section?
Download and install the driver, perform the update again.
Thanks for the help, finally I could isntall the usb driver under win8, and repeated the firmware update again.
IED1.0.4 wifi shield is working fine as before
IDE 1.05: the same sketch is partially running, but is connecting, but the client does not connect when the skecth initiate the HTTP GET. So there are some improvement, but only partial.
I think that still there are some problem with the wifishield or with the IDE 1.0.5
How do you see this?
