I just purchased a Lenovo Yoga 3, 14". It comes with a Qualcomm Atheros QCA61x4 wireless network adapter. I have not been successful getting this wifi to work. I have tried some suggestions for Yogas but they, apparently use a different adapter. I have also tried ndiswrapper without any luck. I downloaded a windows driver which installed fine and indicated that it found matching hardware, but still no wifi.
If I cannot get it working soon, I'll have to send the machine back. Life without Ubuntu is not to be considered. Any assistance would be greatly appreciated.

I was able to get my Qualcomm Atheros 61x4 running on a ubuntu 15.04 clean install. Actually not for the Lenovo model but for an Acer Aspire VN7 Nitro 791G These are the steps I accomplished:

and

Hope this helps.
