Android WiFi state is UNKNOWN

I had a problem when i tried to return the wifi state , disconnected or connected .. well I dont get an exception but it jumps to the else {} block of my if condition, when i was debugging I found that : 

 NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

mWifi has this: NetworkInfo: type: wifi[], state: UNKNOWN/IDLE, reason: (unspecified)

ConnectivityManager connManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
         NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);


        if (mWifi.isConnectedOrConnecting()){

            Toast.makeText(this,"void action Working", 3).show();



        }
        else
        {
            Toast.makeText(this,"void action Not working", 3).show();

        }

You can do it this way:

            final WifiManager wifiManager = (WifiManager) YourActivity.this.getSystemService(Context.WIFI_SERVICE); 

            if (!wifiManager.isWifiEnabled()) {

                wifiManager.setWifiEnabled(true); //If it's, off turn it on.

            }else{

                //Do what you want to do with wi-fi.            

            }

Note also that I have the following permissions set in my manifest (perhaps not all of which are required in your case as I'm implementing wifi direct functionality):

  <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission
    android:name="android.permission.ACCESS_WIFI_STATE"
    android:required="true" />
<uses-permission
    android:name="android.permission.CHANGE_WIFI_STATE"
    android:required="true" />
<uses-permission
    android:name="android.permission.INTERNET"
    android:required="true" />
