Problem in interfacing a servo motor with an arduino wifi shield

I have connected a servo motor with my arduino Wifi shield over a wifi network and trying to control it wirelessly by sending HTTP request to the Shield from the local IP assigned to the shield by the network. I hv used the SimpleWebServerWifi example of the wifi library using the WPA wifi encryption.
But the problem is as I m trying to send the request to the shield, the wifi shield accepts the request executes the instructions of the servo and simultaneously the link gets disconnected. Every time I have to reset the shield for sending requests to control my servo motor.

Is there any solution to this ??????

The general solution is to not try to power a servo from the arduino. Servos need a separate power supply.
