try this code.it might helps you 

    Intent gpsOptionsIntent = new Intent(android.provider.Settings.ACTION_WIFI_SETTINGS); 
     startActivityForResult(gpsOptionsIntent,0); 

if you are using wifiManager than you will need this permission. 

    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
