Something new happened:I managed to turn the green wifi light on by bypassing hardware switch in software:

actually, it only made my wlan hardblocked to yes in rfkill. But I need to put the antenna on with sudo ifconfig wlan0 up at each boot. I'm sure there's a solution to this, but the problem remains: the antenna is up, the encryption is down,but no actuall wifi connection yet.
