I will look into it.

@NeuroSamuel said in Connecting to secondary WLAN interface:

My problem is that I see no way to open a QNetworkSession from one of those configurations choosing the hardware interface.

Is not something you (or your sysadmin) did already when configuring the networking devices for your system?
Not that I have that much experience with QNetworkSession, but it looks that behavior to be fine, given that you are setting one WLAN interface to one SSID at OS level. Thinking of wpa_supplicant on Linux for instance:
wpa_supplicant.conf

network={ ssid="home" scan_ssid=1 key_mgmt=WPA-PSK psk="very secret passphrase" }

and then command line:

wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -d

Because at the end it'll be a question of OS routing, won't it?

Hi,

AFAIK, no. Modifying system settings like that is something that is outside of Qt's scope (I don't meant you can't do it using Qt but it has no direct support for that).

Maybe QNetworkConfigurationManager and friend classes might be of help here.

Hi,

To add to @jsulm, please consider the security hole you might be creating with your application. Storing SSID's and passwords in plain text is a bad idea.
