Hello,
This is my first post, and I hope I'm posting in the right area. I downloaded the new firmware from: http://arduino.cc/en/Hacking/WiFiShieldFirmwareUpgrading and after some troubleshooting, I figured I needed to modify the path in order for the script to find the needed files. The firmware was verified as per the script and completed successfully. However, whenever I try to power up them Arduino Uno with the Wifi Shield (Model R3), no lights or activity show up on the WiFi shield. The serial window displays no text. Did I do something wrong?
