Can someone help? I've tried the recommended fix used for ubuntu 15.10 and the Qualcomm adapter shown in another thread. Unfortunately it is not working for my acer aspire laptop E15 and the Qualcomm Atheros QCA9377 wireless adapter running 15.10. could I be using the wrong terminal commands: 

    sudo apt-get update
    sudo apt-get install linux-headers-generic build-essential
    wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz
    tar -zxvf backports-20151120.tar.gz
    cd backports-20151120
    make defconfig-ath10k
    make
    sudo make install

any help is appreciated 

 sudo modprobe ath10k_pci && dmesg | grep ath

gave the following result:

You are missing needed firmware and missed a parameter setting 

sudo mkdir -p /lib/firmware/ath10k/QCA9377/hw1.0
cd /lib/firmware/ath10k/QCA9377/hw1.0
sudo wget https://github.com/kvalo/ath10k-firmware/blob/master/QCA9377/hw1.0/firmware-5.bin_WLAN.TF.1.0-00267-1
sudo wget https://github.com/kvalo/ath10k-firmware/blob/master/QCA9377/hw1.0/board.bin
sudo cp firmware-5.bin_WLAN.TF.1.0-00267-1 firmware-5.bin

To set the parameter 

echo "options ath10k_core skip_otp=Y" | sudo tee /etc/modprobe.d/ath10k_core.conf

EDIT: Now with kernel 4.3.3 installed, 

cd backports-20151120
make clean
make defconfig-ath10k
make
sudo make install
Reboot

  • I really appreciate your help. Unfortunately it didn't work. Is there sth else I can do? – Gee Jan 17 '16 at 13:52
  • Edit the question to include sudo modprobe ath10k_pci && dmesg | grep ath10k – Jeremy31 Jan 17 '16 at 13:54
  • cat /sys/module/ath10k_core/parameters/skip_otp might show something and does ls /lib/firmware/ath10k/QCA9377/hw1.0 show anything now? – Jeremy31 Jan 17 '16 at 15:37
  • See edit to set parameter – Jeremy31 Jan 17 '16 at 16:42
  • I set the parameter, it's now Y

    Nothing changed after reboot. What else can I try?

     – Gee Jan 17 '16 at 17:13
  • Could you paste your /var/log/dmesg at paste.ubuntu.com and post the URL as something else is going on with the kernel – Jeremy31 Jan 17 '16 at 17:36
  • You could try chili555's answer here but it should do the same, strange as that question involves an Acer Aspire also. You might want to shutdown the computer then restart rather than reboot – Jeremy31 Jan 17 '16 at 19:03
  • thx Jeremy31

    Can I also paste my dmesg? /var/log/dmesg says that I've no authorization.

    Did both - restart and reboot, no results

     – Gee Jan 18 '16 at 11:57
  • See if dmesg > dmesg.txt works and then paste the contents of dmesg.txt at paste.ubuntu.com – Jeremy31 Jan 18 '16 at 12:31
  • it's doing nothing. what about dmesg k – Gee Jan 18 '16 at 13:20
  • It won't show it doing anything but it will create a dmesg.txt file in whatever directory your terminal is in, by default it is in your home folder – Jeremy31 Jan 18 '16 at 21:44
  • ahhh you're right. Sorry I'm new to this. Thank you very much for your patience. – Gee Jan 18 '16 at 22:05
  • Can you paste the contents? – Jeremy31 Jan 19 '16 at 21:34
  • yes I did it yesterday before my last comment, do you need a reference? – Gee Jan 20 '16 at 10:33
  • It should have given a URL to post – Jeremy31 Jan 20 '16 at 11:16
  • you mean this - http://paste.ubuntu.com/14570625/ – Gee Jan 20 '16 at 11:24
  • Download this, this, and this install and reboot. Your dmesg shows that you are experiencing a bug and the 4.3.3 kernel should fix it – Jeremy31 Jan 20 '16 at 22:40
  • thx, I did what you asked, nothing changed - I created a new dmesg.txt:

    http://paste.ubuntu.com/14589640/

     – Gee Jan 21 '16 at 11:41
  • Post a link to dmesg | grep ath10k – Jeremy31 Jan 21 '16 at 21:52
  • what is supposed to happen? – Gee Jan 22 '16 at 15:04
  • Should have printed messages to the terminal window. modinfo ath10k | grep -i alias – Jeremy31 Jan 22 '16 at 15:35
  • dmesg | grep ath10k shows noting and modinfo ath10k | grep -i alias says that: modinfo: ERROR: Module ath10k not found. – Gee Jan 22 '16 at 16:34
  • Sorry modinfo ath10k_pci | grep -i alias – Jeremy31 Jan 22 '16 at 18:40
  • no worries alias: pci:v0000168Cd00000040sv*sd*bc*sc*i* alias: pci:v0000168Cd0000003Esv*sd*bc*sc*i* alias: pci:v0000168Cd00000041sv*sd*bc*sc*i* alias: pci:v0000168Cd0000003Csv*sd*bc*sc*i* – Gee Jan 23 '16 at 10:22
  • Hey Jeremy31, everything ok? do you have any other idea? – Gee Feb 01 '16 at 14:42
  • Is this installed UEFI or BIOS? – Jeremy31 Feb 01 '16 at 15:40
  • I changed UEFI to Legacy in BIOS or I'd have this message - no bootable device – Gee Feb 01 '16 at 21:23
  • You can't switch it that easily, see this It was stated in the bug report for this card that a couple people had to switch from UEFI to legacy to get the card to work – Jeremy31 Feb 01 '16 at 21:59
  • @jeremy31 in this comment thread you suggest using chilli555's answer in another stackexchange post, remarking that it should do the same thing. Thought you might be curious to know that his solution worked for me where this one did not. I'm on an Acer Aspire e5-573G. Thanks for your help here (and for your related posts in the Arch forums) – Dodgie Mar 05 '16 at 02:30
