I applied this fix: http://billauer.co.il/blog/2014/08/linux-ubuntu-
yoga-hardware-blocked-wireless-lan/

Wifi now works flawlessly, but I'm wondering whether I'll need to repeat
the steps when future kernel updates appear.

Title:
  wifi not configurable in network-manager showing disabled by hardware
  switch

Status in “network-manager” package in Ubuntu:
  Confirmed

Bug description:
  Network manager shows Wifi is disabled by hardware switch. It worked jut after install but not anymore after.
  I read somewhere I can use wicd and that does work.
  iwlist wlan0 scan worked also before installing that.
  Seems like a bug in network-manager to me.
  It would be nice if NM does whatever wicd does to enable the wifi card.
  I have nog physical button for wif and wifi is enabled in the UEFI firmware.
