Good. But sometimes the speed is not fast even through in wifi type. so it is inaccuracy in isConnectionFast() method.

Hello, I am using isConnectionFast method by passing context. But when my mobile in 2G with 30kbps around, this method showing the subtype 2 (TelephonyManager.NETWORK_TYPE_EDGE) which is 50~100 kbps is wrong right?

Correct me if I am doing wrong.

Vinod

Do these fast connections with high bandwidth also have low latency? Or might there be some high bandwidth / high latency connection that return true in this isConnectionFast() gist?

wifi speed can be calculated by using

WifiManager wifiObj = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = mainWifiObj.getConnectionInfo();
if (wifiInfo != null) {

Integer linkSpeed = wifiInfo.getLinkSpeed();
String units = WifiInfo.LINK_SPEED_UNITS;

can anyone help me to find mobiledataspeed??

Hi @emil2k , Are there any APIs to check if the WiFi which is connected to, really serves internet or not? whenever the device is connected to WiFi, it considers it as online though the Wifi router does not serve internet or idle. How to check in such situations. I came across pinging some site to detect. But i want to know if there are any APIs which checks the situation.
