Qualcomm Atheros QCA61x4 wireless network adapter

Question

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.

Solution

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:

• install kernel sources: apt-get install linux-headers-(uname -r)
• downloaded the athk master sources from kvalo: git clone https://github.com/kvalo/ath.git
• downloaded the backports tree: "git clone git://git.kernel.org/pub/scm/linux/kernel/git/backports/backports.git"
• built the new backport tree according to the instructions found on linux-wireless: https://wireless.wiki.kernel.org/en/users/drivers/ath10k/backports
• downloaded the firmware from sumdog and copied it to /lib/firmware/ath10k/QCA6174/hw2.1/ :

(Sorry I am not allowed to post more than two links)

"wget github.com/sumdog/ath10k-firmware/raw/5faf5bb7c7413f9bbde54cca6fff58e/ath10k/QCA6174/hw2.1/board.bin"

and

"wget github.com/sumdog/ath10k-firmware/raw/5faf5bb7c7413f9bbde54cca6fff58e/ath10k/QCA6174/hw2.1/firmware-4.bin"

• created athk10 config file as described in this post before: sudo echo "options ath10k_core skip_otp=y" > /etc/modprobe.d/ath10k.conf
• copied firmware-4.bin to firmware-5.bin as dmesg claimed about not finding firmware-5.bin

Hope this helps.

Drat! That's bad news. I also like the format of the machine, but I need wifi. Just to clarify, did you put in the 3160NGW? Can you confirm that it works? Can you clarify the need for a matching FCC ID? In shopping around the FCC ID is rarely listed. Non matched the FCC ID on my machine. Thanks!

I didn't try using one without a matching FCC ID. But I did manage to install the 3160NGW yesterday, and it worked perfectly. The FCC code was not listed in my purchase on ebay where I got the card, but I was able to discern that the card had an FCC ID matching the one in the regulatory notice from the picture of the card that was posted.

WakkaDojo would you mind sharing your purchased FCC ID + photo, and post a link to the ebay seller where you bought your card? I've seen both P93160NG and P93160NGW cards, while the compliance document seems to require P93160NGU. (Just got a Lenovo Yoga 3-14 myself) Sorry this is not an answer per se, just registered and was not allowed to comment - only post an answer. (Weird policy)

The links I posted contain the answers to everything you asked. The FCC ID must be PD93160NGU, with the U, as is stated in the compliance document above. This is the one I bought: link. It's a little hard to find but they're out there.
