Title:
  "Wi-fi disabled by hardware switch" permanently on Lenovo Yoga 2 13

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've a Lenovo Yoga 2 13" and installed Wily from a thumb drive (no
  upgrade).

  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.

  It came as a surprise as I was previously using Vivid on this laptop
  and wi-fi worked out of the box with it, never giving me any problems.
