Unity with Arduino+WiFly

Hello everyone, I have an Arduino with a WiFly module hooked to it. All it does is create a Wireless Access Point with an ip address (169.254.1.21) that talks on port 2000. Here I have the code to connect to it and listen to the socket from Unity

 using UnityEngine;
 using System.Collections;
 using System;
 using System.IO;
 using System.Net.Sockets;
 //using System.Globalization.NumberStyles;
 
 public class wifly : MonoBehaviour
 {
 public string tekst;
 
     internal Boolean socketReady = false;
     TcpClient mySocket;
     NetworkStream theStream;
     StreamWriter theWriter;
     StreamReader theReader;
     String Host = "169.254.1.21";
     Int32 Port = 2000;
     
     void Update()
     {
     string receivedText = readSocket();
         if (receivedText != "")
         {
         tekst=receivedText;
         print(tekst);    
         }
     }
 
     void OnGUI()
     {
     if (!socketReady)
       {    
           if (GUILayout.Button("Connect"))
           {
           setupSocket();
           }
       }
 
     if (socketReady)
       {    
       //print (tekst);
       }
     }
 
     void OnApplicationQuit()
     {
         closeSocket();
     }
 
     public void setupSocket()
     {
         try
         {
             mySocket = new TcpClient(Host, Port);
             theStream = mySocket.GetStream();
             theReader = new StreamReader(theStream);
             socketReady = true;
         }
 
         catch (Exception e)
         {
             Debug.Log("Socket error: " + e);
         }
     }
 
     public String readSocket()
     {
         if (!socketReady)
             return "";
         if (theStream.DataAvailable)
             return theReader.ReadLine();
         return "";
     }
 
     public void closeSocket()
     {
         if (!socketReady)
         return;
         theReader.Close();
         mySocket.Close();
         socketReady = false;
     }
 }

I have a strange problem with it though, sometimes it works, sometimes it doesn't. The Arduino sends a message every second and I'm showing it in the console in Unity. When I play the scene it gives me an error that it could not connect to the host address. Although, I observed that it works in one case, if I first connect to the wifi point it created, then use telnet to: "telnet 169.254.1.21 2000", and after that start the unity scene, it works like a charm, as soon as I exit the telnet command prompt it loses the connection and doesn't receive any messages. Could someone explain to me how I can resolve this issue? Thanks.
