Log.i(TAG, "No connection");
} else {

if (netType == ConnectivityManager.TYPE_WIFI) {
Log.i(TAG, "Wifi connection");
WifiManager wifiManager = (WifiManager) getApplication().getSystemService(Context.WIFI_SERVICE);
List<ScanResult> scanResult = wifiManager.getScanResults();
for (int i = 0; i < scanResult.size(); i++) {
Log.d("scanResult", "Speed of wifi"+scanResult.get(i).level);//The db level of signal
}
// Need to get wifi strength
} else if (netType == ConnectivityManager.TYPE_MOBILE) {
