[1.] "Wi-fi disabled by hardware switch" permanently on Lenovo Yoga 2 13
[2.] Full description of the problem/report:
Can't use wifi at all. The indicator panel says "Wi-fi disabled by
hardware switch". Pressing the "airplane mode" key makes no difference.
Once I blacklisted ideapad_laptop kernel module, I did get wi-fi back.
But after a couple of minutes it would become slow and unreliable to be
point of being unusable.
Also the "? /" key doesn't work at all (it has a pt-BR keyboard layout)
It all works fine under Win 8 (the OS that ships with this laptop).
