Hello,
I am doing now a project in which i have to implement a mobile roboter which has to be controlled by a webinterface. My english is not very good so please dont be severe with me :).
I have an arduino uno r3 and the wifi shield, additionally the stepper motors are controlled with the arduino motor shield. First of all I uploaded the wifi shield firmware as posted on the forum, but at the beginning it did not work, but now it is working fine. I can scan the networks around me, and the program "WifiChatServer" is working very well. The green "LINK" Led is on when i am uploading the program, and when i am executing the wifichatserver program, then the blue "DATA" Led is on. This means that my arduino is receiving datas from my laptop. The big problem is when i am uploading any program in which i have to control a led or motors with a webinterface. For instance when i uploaded the "SimpleWebServerWifi" in which i can control a led over the internet, it does not work as it should. When i open the server with the ip adress and when i click on "led on" then the led is on but i can not turn it off!!!!! The blue data led is blinking as it should, so to me it has to work. IP routing is activated. When i am uploading a program in which i have to turn a stepper motor on and off, i have to press so many times on the "motors on"-button to work. I just want that when i am pressing only ones the button that it turns on or off, but i have to click so many times that something happens. I have checked the firmware and it is up to date, but my big concern is that i have made something wrong with the uploading of the firmware. At the beginning i wanted to upload the firmware by the cmd control panel, then i used the avr32 studio. Sometimes the error lamp is on, i dont now why. Sometime the wifi shield is not working when i dont attach the second usb cable to the shield. I have made a jumper between pin 7 and 3 but nothing happens. I really do not understand why the wifichatserver-program is working fine, but the led control program is not working. These two programs are similar to me, because when i am executing putty.exe and i am using the ip adress of the shield, the serial monitor is receiving datas from a client, but on the other hand the simplewebserverwifi-program is not working. As I said I have to press so many times on the button to have an action!!!! Maybe this is a dhcp problem but i am not a network specialist 
So please help this little fool...
