AutoIT as server and Arduino + WiFi Shield as client

Projects Programming

Hello everybody
I have a little problem: Instead of using the Arduino connected to the WiFi shield as server and communicating with it with GET requests, I now try to establish a TCP connection between my AutoIT program as server and the Arduino as client (Because the Arduino as server doesn't work right). But I can't get it working, although I used example codes.
The IP of my laptop: 192.168.2.103
The IP of the Arduino: 192.168.2.128

The AutoIT code:

Global $MainSocket = -1
Global $ConnectedSocket = -1
Local $MaxConnection = 1; Maximum Amount Of Concurrent Connections
Local $MaxLength = 512; Maximum Length Of String
Local $Port = 3178; Port Number
Local $Server = @IPAddress1; Server IpAddress
MsgBox(0,"",$Server)
TCPStartup()
$MainSocket = TCPListen($Server, $Port)
If $MainSocket = -1 Then Exit MsgBox(16, "Error", "Unable to intialize socket.")
While 1
    $Data = TCPRecv($ConnectedSocket, $MaxLength)
    If $Data = "~bye" Then
        MsgBox(16, "Session Ended", "Connection Terminated.")
        Exit
    ElseIf $Data <> "" Then
; Unconditional Receive
        MsgBox(0, "Received Packet", $Data)
    EndIf
    If $ConnectedSocket = -1 Then
        $ConnectedSocket = TCPAccept($MainSocket)
        If $ConnectedSocket <> -1 Then
; Someone Connected
            TCPSend($ConnectedSocket, "Connected!")
        EndIf
    EndIf
WEnd
Func OnAutoItExit()
    If $ConnectedSocket <> - 1 Then
        TCPSend($ConnectedSocket, "~bye")
        TCPCloseSocket($ConnectedSocket)
    EndIf
    If $MainSocket <> -1 Then TCPCloseSocket($MainSocket)
    TCPShutdown()
EndFunc;==>OnAutoItExit

  // if there's no net connection, but there was one last time

The list goes on and on. Can someone take a look and tell me why it doesn't work?
