Public bug reported:
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.
