So I've copied deviskec post and fixed the recent breakage due to the merge of ominous 'ath-next' branche which broke ath10k.
1. Download the firmware binaries https://github.com/sumdog/ath10k-firmware/raw/5faf5bb7c7413f9bb332693179de54cca6fff58e/ath10k/QCA6174/hw2.1/board.bin https://github.com/sumdog/ath10k-firmware/raw/5faf5bb7c7413f9bb332693179de54cca6fff58e/ath10k/QCA6174/hw2.1/firmware-4.bin and put them in the /lib/firmware/ath10k/QCA6174/hw2.1/ folder (create the folder if it doesnt exist) Commands: sudo mkdir -p /lib/firmware/ath10k/QCA6174/hw2.1/ sudo wget https://github.com/sumdog/ath10k-firmware/raw/5faf5bb7c7413f9bb332693179de54cca6fff58e/ath10k/QCA6174/hw2.1/board.bin -O /lib/firmware/ath10k/QCA6174/hw2.1/board.bin sudo wget https://github.com/sumdog/ath10k-firmware/raw/5faf5bb7c7413f9bb332693179de54cca6fff58e/ath10k/QCA6174/hw2.1/firmware-4.bin -O /lib/firmware/ath10k/QCA6174/hw2.1/firmware-4.bin 2. Install dependencies to be able to compile the kernel with: sudo apt-get install libncurses5-dev gcc make git exuberant-ctags 3. Download kvalo's kernel tree from: https://mega.nz/#!9A8UTLLL!7CDjBmSwNTudX9Upz6yRk7BabKE4w2J8_GCwLrKh27c NB: I could find a link to the correct, RC7 zip. Perhaps it's already fixed in the master branch, otherwise use my uploaded mega link and extract it to a folder (no need to apply any patch, it's been merged already). NB: I couldn't get this to work with the command line unzip, so use the gui extraction tool. 5. Navigate to the extracted folder and run the following commands: cp /boot/config-`uname -r`* .config make olddefconfig make -j`cat /proc/cpuinfo | grep -c processor` (this automatically uses the best amount of jobs for your CPU) (wait a while for it to compile, and after run) sudo make INSTALL_MOD_STRIP=1 modules_install install (stripping symbols makes the initrd the regular ~30MB instead of 238MB) 6. Create config file with: echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k.conf 7. Reboot using your new kernel 4.x.x-wl-ath (will be automatically selected) 8. Run ifconfig Works perfectly without any drops. Would be nice that people who succeed comment on the following PR: https://github.com/kvalo/ath10k-firmware/pull/2 so we can get this merged to mainstream kernel. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1383184 Title: Atheros Qualcomm Killer N1525 Wireless-AC [168c:003e] not supported Status in linux package in Ubuntu: Triaged Bug description: Card detail: Qualcomm Atheros Device [168c:003e] (rev 20) Subsystem: Bigfoot Networks, Inc.
