Hello,
I'm having a great deal of difficulty getting my WiFi shield to work as a web server. IDE 1.0.5. I have the Uno V3 and shield V3. My router is reserving an IP for the MAC of the shield. The Shield reports firmware as 1.1.0. I have tried several different elf and hex files with little success. The serial connection reports that there is a new client, however, my browsers (firefox and ie) do not display anything (the browser is within the same subnet). I've attached the firmware files that worked the best. I'm hoping that between the files and the code below, someone will be able to point me in the right direction. I'm not sure if this is the same issue as the 'Issue 10' that was also reported, but I thought I'd start here.
Also,do the .c and .h files have to be in a certain place or are they for development?
Thank you in advance.
Eric

WiFi Web Server
A simple web server that shows the value of the analog input pins.
using a WiFi shield.
This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.
Circuit:
- WiFi shield attached
- Analog inputs attached to pins A0 through A5 (optional)
