Hi,
I am making a project to monitor certain parameters on xively.
I am using:
- Arduino 1.0.5 r-2 I.D.E.
- Arduino uno R3
- Arduino wifi shield with WiFi firmware version: 1.1.0. (upgraded firmware to last version).
My Sheild was working good just had a issue that after 40-50 mintues it got hanged and it stop sending data on server.
I Googled and found that if i update firmware this will be fixed but after firmware update it is not sending data on server.
It is not able to connect also.
All happened after updating the firmware.
I updated it from the file on arduino website but my shield is not working after successfull firmware update.
Can i get the firmware which was originally programmed in the wifi shield.

Wifi Xively sensor client with Strings
This sketch connects an analog sensor to Xively (http://www.xively.com)
using a Arduino Wifi shield.
This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.
This example has been updated to use version 2.0 of the xively.com API.
To make it work, create a feed with a datastream, and give it the ID
sensor1. Or change the code below to match your feed.
This example uses the String library, which is part of the Arduino core from
version 0019.
Circuit:
* Analog sensor attached to analog in 0
* Wifi shield attached to pins 10, 11, 12, 13
