Wlan auto configuration error in Windows.

Hi!,
I have a problem. I'm using windows 7 home premium, and I encountered a problem. The image is attached here. I searched over the internet on how to solve this problem but until now no solution found. I tried to set my msconfig to default because thinking that other program may be at the start up is the cause of the problem.
