@SurferTim,

This is modified version of your code(http://www.arduino.cc/playground/Code/WebClient)

It works like a charm but I am still not sure if it is still stable. I mean your part of code is great, but what I did might be changed the stability.

What do you think?

Serial.println("Timeout");
client.stop();
}

}

Serial.println();

Serial.println("disconnecting.");
client.stop();

return 1;
}

What does this connectLoop do by the way? It is just for testing i suppose, right?

connectLoop++;
    if(connectLoop > 100)
    {
      Serial.println();
      Serial.println("Timeout");
      client.stop();
    }

...and here is the serial print:

Pass 1431
connecting...connected
Speed 1:706

disconnecting.
Pass 1432
connecting...connected
Speed 1:706

disconnecting.
Pass 1433
connecting...connected
Speed 1:706

disconnecting.
Pass 1434
connecting...connected
Speed 1:706

disconnecting.
Pass 1435
connecting...connected
Speed 1:706

disconnecting.

Thank you in advance
