I'm trying to upgrade firmware on my wifi shield by following the upgrade instructions for Mac. I was wondering what this means?:
Connect a jumper on the J3 connector, that put the shield in the programming mode. Then connect the USB cable to the shield USB mini socket
How can I do this?
A "jumper" is a little piece of metal (or a 0-ohm resistor) that connects two pads or pins together. So, create an electrical connection across J3 ("DFU programming jumper" in all the pictures). You will then be able to program the shield via USB.
The jumper is only neccesary if your device is not R3 (revision 3) Be carefully if you connect the shield and your computer does not recognice the port. You gonna need a driver in the link below there are all the steps include other links to download software as Flip 3.4.7 who has the executable batchisp which one you can made the changes read the web site:
http://www.dfrobot.com/community/?p=3760
and extra information about that in official site of arduino WiFi Shield Firmware Upgrading
there you gonna have an idea how to do it.
for me was more clear as in this site describe everything and also teach to probe if there is an update having sucess in the process to installing something it could be as a question answered with non the specific thing you need.

I am also in the process to update my device if I will have success I will write to how I do it. At the moment reading a bunch of differents forums beacuse arduino team itself appearently had some troubles to provided a guided how to do it sucessfully.
