short prestory: i've decided to updrade my internal wlan card. turns out not all lenovo models are open to all cards and on boot, if the change is attempted, it's normal to get something like "unauthorized network card is detected". system is halted until you reboot, put in the original card, and boot again. however:
the original card gives me kukish:
not only the airplane mode seems to be permamently enabled, the card itself is not listed anymore in the output of lspci. Only ethernet controller is detected, but the above message on boot disappears. I am assuming it means that the card is not visible, but somehow detected.
so. i boot again, plug in the cable and:

and the same blasted airplane mode.
windows 7 connects through the cable ok, booting into a live distro is good too.
what am i missing? thank you all in advance.
