Hello! I don't think you've understood the situation. I do understand how interfaces are added in the system, and I do have two wireless interfaces on my system - wlan0 and wlan1. Both are tested and working. Wpa_supplicant supports managing multiple wireless cards simultaneously - there are fancy command line switches for it and so on. There's a "interface_add" command which can be passed to a running wpa_supplicant instance which is already managing one card, and that command tells it it has one more interface to manage. From what I've understood, wpa_cli accepts this command, passes it through a control socket to a running wpa_supplicant instance and receives an "UNKNOWN COMMAND" reply message for some reason. That's the problem I'm dealing with.
Best regards, Arsenijs.
