[Bug 1503438] Re: "Wi-fi disabled by hardware switch" permanently on Lenovo Yoga 2 13
I managed to get Win8 back into it again so I could update the BIOS.
It's the latest one now (1.17).
Bug persists though :(
One thing I think I should mention is that between its Vivid (when all
was working fine) and its Wily (what I have now) incarnations I had it
sent back to Lenovo factory for repairs due to a broken USB 3.0 port
(the blue tab broke off, common issue with this model). So they
repaired the USB port but also reflashed/reset the BIOS and HDD as well
(as usual). It's the same motherboard though as the mac address remained
the same.
Output of "sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date":

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.
