I followed the instructions in the top answer here:

My wifi Qualcomm Atheros Device [168c:0041] (rev 20) doesn't show up and work in Ubuntu 14.04.3 on Lenovo flex 3 14

But got:

(Reading database ... 323177 files and directories currently installed.)
Preparing to unpack backath10k-dkms_2.0_all.deb ...

------------------------------
Deleting module version: 2.0
completely from the DKMS tree.

Consult /var/lib/dkms/backath10k/2.0/build/make.log for more information.

I have linked the contents of the make.log in the following pastebin: http://pastebin.com/dnuAvDfE

What should I do?

EDIT: I have run 'sudo dkms remove backath10k/2.0 --all' and I got this esult: http://pastebin.com/UVyiZTLp I am still unable to connect.

EDIT: Solved! See Jeremy's comment below

Ubuntu 16.04 users should not use backports or any dkms package as the 16.04 kernel supports more devices than previous versions. You need to set the skip_otp parameter and install firmware in most cases. The firmware that works is from https://github.com/atondwal/ath10k-firmware.git

Only use this firmware if you have 

02:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:0041] (rev 20)
    Subsystem: Lenovo Device [17aa:3545]

echo "options ath10k_core skip_otp=Y" | sudo tee /etc/modprobe.d/ath10k_core.conf
git clone https://github.com/atondwal/ath10k-firmware.git
sudo cp -r ath10k-firmware/ath10k/ /lib/firmware/
cd /lib/firmware/ath10k/QCA6164
sudo cp -r hw2.1/ /lib/firmware/ath10k/QCA6174/

|| Step Wise Guide to Resolve the Wifi Issue in Lenovo Z51-70 ||

  1. Download the tar.gz file named Wifi-70 from this link - Wifi70.tar.gz

  2. Extract the tar.gz file in your desired location/directory

(eg. /home directory)

tar -xzvf Wifi-70.tar.gz -C /home
  1. Go to the folder named - backports-20150731 in Wifi-70 directory through terminal ; Just right click the folder and open in terminal

Then run the following command (We are just trying to compile the code here)

sudo make install
  1. Once this is done go to the folder named ath10k-firmware-master in Wifi-70

Then run the following below commands

sudo cp -R ath10k/ /lib/firmware/

sudo bash -c 'echo "options ath10k_core skip_otp=y" > 
/etc/modprobe.d/ath10k.conf'
  1. Now reboot the system. After reboot run the following command.

(it will throw error if you run without reboot)

sudo modprobe ath10k_pci

Hope, it will resolve your issue :)

Your driver requires firmware that is missing:

Direct firmware load for ath10k/QCA6174/hw2.1/board-2.bin failed with error -2

With a working internet connection by ethernet, tethered or whatever means possible, please open a terminal and do:

sudo apt-get update
sudo apt-get install git
git clone https://github.com/kvalo/ath10k-firmware.git
cd ath10k-firmware/QCA6174/hw2.1
sudo cp  *  /lib/firmware/ath10k/QCA6174/hw2.1
cd /lib/firmware/ath10k/QCA6174/hw2.1
sudo mv firmware-5.bin_SW_RM.1.1.1-00157-QCARMSWPZ-1  firmware-5.bin

Reboot.
