Wlan connection issue

[Cobra91151]

Hi! I want to connect to the wireless access point using WlanConnect function.

Code:

HANDLE hClient;
PWLAN_INTERFACE_INFO_LIST pIfList;
PWLAN_INTERFACE_INFO pIfInfo;
PWLAN_AVAILABLE_NETWORK_LIST pBssList;

DWORD dwResult = 0;
WLAN_CONNECTION_PARAMETERS connectionParameters;
memset(&connectionParameters, 0, sizeof(WLAN_CONNECTION_PARAMETERS));
connectionParameters.wlanConnectionMode = wlan_connection_mode_profile;
connectionParameters.strProfile = pBssList->Network[apIndex].strProfileName;
connectionParameters.dwFlags = 0;
connectionParameters.pDot11Ssid = NULL;
connectionParameters.pDesiredBssidList = 0;
connectionParameters.dot11BssType = dot11_BSS_type_any;
dwResult = WlanConnect(hClient, &pIfInfo->InterfaceGuid, &connectionParameters, NULL);

if (dwResult == ERROR_SUCCESS) {
    qDebug() << "Connected!";
} else {
    qDebug() << dwResult;
}

When connecting to open AP I get 87 error code, it means the wrong parameter. Any ideas what parameter can be wrong? Thanks in advance.

Hi,

How is that related to Qt ?

@SGaist

The application is built with Qt framework, but since Qt doesn't have Wireless API, I use native Wlan API. So it's related now.

[SGaist]

From a Qt POV, it looks like QNetworkSession and QNetworkConfiguration might be what you are looking for.

However I have to disagree with your point: you are using a Windows native API. The fact that you are using Qt to build your application doesn't make asking what parameters your should use for the WlanConnect method a Qt related problem. The Microsoft forums might be a better place to learn how to use that method.

As a note. you did see
https://msdn.microsoft.com/en-us/library/windows/desktop/ms706613(v=vs.85).aspx
and the list of reason why/when it would return ERROR_INVALID_PARAMETER ?

@SGaist

Ok. I will try your suggestion.

I have figured it out and fixed the issue. The issue was that the WlanSetProfile function was not set before the WlanConnect function.
