Detecting WiFi network

SGaist

Might be a silly question: is your WiFi device enabled ?

ashajg

YES my device is enabled

I'm loosing my nerves with this, too. I didn't notice this topic but wrote in the General section: https://forum.qt.io/topic/96157/how-to-get-the-current-ssid-what-are-qnetworkconfigurations. I just don't understand what these classes are even supposed to do.

@SGaist

What all things can i try to solve this problem??
Is there a problem in code ??

SGaist

A call to updateConfigurations is likely required.

ashajg

ok i ll try that.

ashajg

@SGaist
I tried but nothing happened

I have found this
https://forum.qt.io/topic/47384/qt-connecting-to-wireless-networks/4

what is qgenericbearer.dll and qnativewifibearer.dll and is it needed for this program??

SGaist

The bearer plugins are responsible for providing the backend to the system networking capabilities so yes they are needed but the names are not the same for all the platforms.

ashajg

Ok @SGaist

In my Qt , I checked and found that in plugin/bearer I don't have qnativewifibearer.....

Do I just need to download it and paste it in my Qt plugin folder??

SGaist

What plugins do you have ?

Eeli K

It looks like QNetworkConfigurationManager can't be trusted nowadays, see for example https://bugreports.qt.io/browse/QTBUG-68613 and https://bugreports.qt.io/browse/QTBUG-65586.

ashajg

I have qgenericbearer.dll only @SGaist

ashajg

Hi @Eeli-K what else can I use other than QNetworkConfigurationManager if I want to use unpaid version of Qt...

Eeli K

I think you have to use platform-native APIs instead of Qt.

dheerendra

Did you solve this issue using native APIs ?

ashajg

Hi sir @dheerendra
sorry for late reply..
I didn't tried with native APIs.
But when I am trying the above code with Android device I am getting this output
CODE:

QStringList WiFisList;
QNetworkConfiguration cfg;
QNetworkConfigurationManager ncm;
auto nc = ncm.allConfigurations();
    for (auto &x : nc)
    {
        qDebug()<< "CHECK1  " << x.bearerType();
        if (x.bearerType() == QNetworkConfiguration::BearerWLAN)
       {  qDebug ()<<"CHECK2";
          qDebug() <<"WIFI is"<<x.name();
       }

OUTPUT:

D libWiFi.so: ..\AshishTest\main.cpp:19 (int main(int, char**)): CHECK1   1
D libWiFi.so: ..\AshishTest\main.cpp:19 (int main(int, char**)): CHECK1   2
D libWiFi.so: ..\AshishTest\main.cpp:21 (int main(int, char**)): CHECK2
D libWiFi.so: ..\AshishTest\main.cpp:22 (int main(int, char**)): WIFI is "Mobile"
D libWiFi.so: ..\AshishTest\main.cpp:19 (int main(int, char**)): CHECK1   2
D libWiFi.so: ..\AshishTest\main.cpp:21 (int main(int, char**)): CHECK2
D libWiFi.so: ..\AshishTest\main.cpp:22 (int main(int, char**)): WIFI is "WiFi"
D libWiFi.so: ..\AshishTest\main.cpp:19 (int main(int, char**)): CHECK1   7

For android device it is entering inside if (x.bearerType() == QNetworkConfiguration::BearerWLAN) as it is printing check2.
just the problem is that output is WIFI is "WiFi" instead of wifi name I am getting "WiFi" as output . Is something missing in my code?

@Mohan1997
On Android is not support, you need to implement it with AndroidExtras and calling directly java class
