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.
