title: How to update arduino wifi shield firmware?
body: <p>I am having trouble following the procedure on the Arduino website to update the wifi shield firmware. Here's the <a href="http://arduino.cc/en/Hacking/WiFiShieldFirmwareUpgrading#.UyT9kvldW6w" rel="nofollow">link</a>.</p>
  
  <p>The outlined procedure is hard for me to follow, including what files to download from Github and where to store them on my computer.  </p>
  
  <p>I then am unsure of exactly what to enter in the command prompt.</p>
  
  <p>Also, the error I was getting in the command prompt is when <code>Opening Port- Fail could not open USB device</code>
  This would make me think that I need drivers or something, but nowhere I searched has said this.</p>
  
  <p>I have done lots of searching and I can't find any good tutorials on how to upgrade the wifi shield firmware on a windows computer.
  Any help or suggestions would be much appreciated!

  <p>I finally figured out how to upgrade the firmware and I documented the process. However, I am unsure of how to post the process that I saved as a pdf and Word document.</p>
