2013-12-09 22:40:57 Hey lufell,
The blink example often drives me crazy! I always forget what sketch is uploaded.. A very good way is to always include a Serial.print("version of sketch and purpose") on the setup for every project you use with serial port. This way, when you do AT commands and other serial communication, this message will pop up and remind you to turn off / disable the serial port.
Follow up this post for connecting to a website, there is a work in progress to do this task:

Jose 2013-12-09 21:51:31 Thanks for your reply.
I have a question one more.]
Do I send a data via wi-fi shield to my remote server?
I can't find tutorial about that. pleas give me an advice. lufell

lufell 2013-12-09 20:26:32 Really?
Example code "blink" doesn't use the serial port. But if the serial port was occupied, it won't receive any signal from the serial port.
OK, anyway, congratulation!
This module is very interesting. You can control many things with it. Grey.CC

Grey.CC 2013-12-09 20:06:01 Hi, I solved problem. it's simple.
I forgot the Hardware setting step 1 that "Program a simple led blinking sample code for your Arduino UNO first to avoid the serial communication conflict between USB port to the WIFI shield."
Thanks! lufell

Yeah, the only way I got your picture is that I changed baud rate. Grey.CC

Grey.CC 2013-11-22 22:21:22 so, you're using your shield for inputting at command right?
are you sure your wifi shield configuration are correct?
for at command, move the run/program switch to run, and usb/arduino switch to usb

It seems that the baud rate is not 115200
Try another or set it again
use AT command "ATB=115200,8,N,1" to set baud rate to"115200"
And don't forget to save the change ;) Grey.CC
