may help you . 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 : , You can do it this way:
code :
            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.            

            }
  <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" />

will be helpful for those in need The short answer is no, you currently cannot determine the current state of the network adapter.
Android does not allow you to go that deep into the system. However, you could estimate the state on your own when watching the values in these four files:
code :
/sys/devices/virtual/net/<InterfaceName>/statistics/tx_packets
/sys/devices/virtual/net/<InterfaceName>/statistics/rx_packets
/sys/devices/virtual/net/<InterfaceName>/statistics/tx_bytes
/sys/devices/virtual/net/<InterfaceName>/statistics/rx_bytes

seems to work fine You have not initialized the WifiManager object. do it in onReceive method in this manner
code :
mainWifiObj = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);

seems to work fine All routers can be reset to their original factory settings, typically by using a paper clip, to push some switch inside a small hole at the back. Do that, and you will be able to reconfigure your router.

fixed the issue. Will look into that further For WPA*, if you don't set the preSharedKey to 8 or more characters this will fail with -1. I don't see you setting it at all.
