I want to know if somebody can tell how can I get the rate of wifi connection on my android phone?
You find the connection speed programmatically in Android as follows:
WifiManager wifiManager = Context.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
if (wifiInfo != null) {
Integer linkSpeed = wifiInfo.getLinkSpeed(); //measured using WifiInfo.LINK_SPEED_UNITS
}
Note that you should use the ConnectivityManager to state your preferred network if you are anticipating use of wifi over other available networks, otherwise the speed may not actually be in use

I know it is very simple for you. Here I am just tried to get WiFi name in android pie devices. I am able to get WiFi name till Nogout devices with the help of below line of code.
String ssid = wifiInfo.getSSID();
I have tried lots of answer and Android developer docs but unfortunately, I can not get a WiFi name on my mobile(Nokia 6.1 plus). I Know I am doing mistakes.
I just want a code there I can get a wifi name from my mobile to my android studio logcat.
This is related to permissions....since API level 27 you need either ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permission. You may also need CHANGE_WIFI_STATE for Android 9 (that's the case for wifi scan anyway as per google permisson model
then try this code
ConnectivityManager connManager = (ConnectivityManager) activity.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
if (networkInfo.isConnected()) {
WifiManager wifiManager = (WifiManager) activity.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
wifiInfo.getSSID();
String name = networkInfo.getExtraInfo();
String ssid = "\"" + wifiInfo.getSSID() + "\"";
}
Try to get SSID value using
WifiManager wifiManager = (WifiManager)
context.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiInfo = wifiManager.getConnectionInfo();
if it returns SSID as null, then turn on the location and try the same.
Oreo 8.1+ devices require the coarse location runtime permission as well as location services to be turned on before retrieving the connected SSID.

Given that, i have only WiFi networks available on the device and no mobile networks, only WiFi.
If I cheecked the connectivity to a network using connectivityManager and the result of it is that "I am connected", does that mean I am also connected to a WIFIalso? If yes, why I can not get info about my WiFi such as ssid,speed, link speed, ip and others from the Connectivity Manager object? Because, to have such info you have to be connected to a WiFi first.
You can check if you are connected & connected to a Wifi
ConnectivityManager cm =
(ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
boolean isConnected = activeNetwork != null &&
activeNetwork.isConnectedOrConnecting();
boolean isWiFi = activeNetwork.getType() == ConnectivityManager.TYPE_WIFI;
You can use Wifi Manager to get the information about Wifi Network
WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();

I think being connected to a network indicates that you are connected to the internet whether through WiFi, Mobile network, Bluetooth or any other network.
And if you are connected to the internet through a WiFi, then, of course, you have connected to a network but through a specific network.
So, the connectivity manager class, has all the network info about the network through which you are connected to the internet. and since it is a generic class you can obtain info about the network through which you are connected to the internet.
I want to get my mac address on my android mobile, without using the Wi-fi or Bluetooth, programmatically in android.
How can I do this?
WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo wInfo = wifiManager.getConnectionInfo();
String macAddress = wInfo.getMacAddress();
Dont forget to add permission for ACCESS_WIFI_STATE
I want to learn the connected wif-fi point SSID. By doing so, I will not try to connect to the same point. How can I learn SSID of that I am connected to wifi point ? Is there a method like isConnected() ?
WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
Log.d("wifiInfo", wifiInfo.toString());
Log.d("SSID",wifiInfo.getSSID());
you will need the android.permission.ACCESS_WIFI_STATE in your manifest
There is one problem:
I selected wifi "XYZ" whoz pwd was unknwn. Entered some random pwd.
It shows authentication problem. on wifi screen.
But, Log.d("SSID",wifiInfo.getSSID());
Results into "XYZ"
I know how to determine if a wi-fi connection is the active connection. However, can someone tell how to determine which wi-fi network is the current active?
Use WifiManager.getConnectionInfo(). This returns a WifiInfo object which contains all the info you need about the active wifi connection; in particular, WifiInfo.getSSID() will give you the SSID.
WifiManager wifiManager = (WifiManager) mContext.getSystemService(Context.WIFI_SERVICE);
String BSSID=wifiManager.getConnectionInfo().getBSSID();
