Windows 10 Tablet QNetworkConfigurationManager not online if WIFI

[ekkescorner]

@kshegunov there are no active configurations listed if connected via WIFI, if connected via LAN, Ethernet configuration is active.

Browser can access internet in both cases: WIFI and LAN

unfortunately I don't have a windows device here with WIFI adapter - next week I'll get a customer device.

Developing since 40 yrs now, but never did Windows development before ;-)
on Android WIFI connection works well

found something similar: https://stackoverflow.com/questions/48768295/qnetworkconfigurationmanagerallconfigurations-doesnt-list-wlan

as soon as I'll have a device here I can explore it in detail

are you really sure you wanne start now? ;)

[ekkescorner]

@aha_1980 hehe ;-)
one of my best customers running my QQC2 apps on Android and iOS now also needs to run the apps on Windows 64 pro 64 Touchscreens - so there's no way around
thx to Qt I can use the same src
have adjusted the UI, mastered the deployment process (Qt Installer Framework on TODO), all works well from devices connected to LAN, but fails on WIFI

Hi,

I think QTBUG-65586 might be of interest.

The wifi bearer plugins were disabled from the regular build due to network performance issues due to the scanning being performed. For windows, you can compile the nativewifi bearer plugin, install it into your Qt being used, and it will work.

[ekkescorner]

@SGaist thx mentioning this bug. on iOS I'm using native classes (ReachabilityListener.mm) - is there a way to use native windows classes same way ?

[ekkescorner]

@lorn.potter I have no idea how I should compile the wifi bearer plugins.
couldn't imagine that such basic stuff - detect if device connected via wifi - doesn't work

[ekkescorner]

@lorn.potter found qnativewifibearer.dll here: https://www.dllme.com/dll/files/qnativewifibearer_dll.html
my customers copied the dll into release/bearer folder and now it is working.

now it would be a good question HowTo compile the dll by myself instead of downloading from web

@ekkescorner
I'm surprised, that should be part of the qt installation

path\to\Qt\5.XX.X\msvc20XX\plugins\bearer

but I noticed it's absence in my installation as well! I still have it in my original deployment folder from one of the older versions, apparently.

[ekkescorner]

@J.Hilk I don't have older installation folders for windows - just started Windows development after years of android/iOS/ (BB10)

[kshegunov]

If you want only the plugin it should be enough to run qmake from the Qt distribution you're using in the plugin folder and then nmake/mingw32-make ...

[ekkescorner]

@kshegunov I don't have mingw - only installed MSVC2017 and Qt 5.12

That's fine, I just didn't know what compiler you chose. So you invoke nmake (msvc's version of make) after calling qmake. Unless there's some oddity it should compile. You are probably also going to need the Windows SDK for the import library files and headers and such.

[ekkescorner]

@kshegunov as a mobile-app-developer and IDE-user and no-cmdline-expert I have no idea what parameters I have to set for qmake ;-)
this is the content of my plugins/bearer folder where the native wifi plugin is missed

[ekkescorner]

@J.Hilk perhaps the easiest way for me is to download an older version of Qt and copy the dll
what was your newest version of Qt where the native wifi dll was contained ?

[kshegunov]

To be absolutely frank, I rarely compile on windows, and I haven't really checked the mentioned plugin in detail, so I'm of little help here. But I took a quick peek and the nativewifibearer uses the private classes, so you almost certainly would need to build Qt from scratch to be sure everything is as it should be binary-wise. If you decide to do that, before actually building you should add whatever plugin you want to the SUBDIRS variable at the end of the qtbase/src/plugins/bearers/bearers.pro file.

[ekkescorner]

@kshegunov thx. think I don't want to do this ;-)
will see to copy the dll from an older Qt version and open bug report

I have no idea, I usually remove older versions from my hd.
The creation date is june 2017, so 5.9 LTS ?

@J.Hilk thx - will try this
