Getting Killer Wireless-AC 1535 working for installing Ubuntu 16.04

  • 772

My wireless device is 168c:003e:1a56:1353 rev 32. The installer contains a 4.4.0-21-lowlatency kernel, and I see firmware files in /lib/firmware/ath10k/QCA6174/hw3.0 There is a board.bin and firmware-4.bin. These are the stock files. In dmesg I see that the initialization fails, and that's true, I don't even see a device in ifconfig. During initialization it is looking for a firmware-5.bin, which is not there.

First I tried to add firmware-5.bin cooked here: https://github.com/kvalo/ath10k-firmware/pull/4/files

That didn't help, the magic in the file doesn't match. I guess it's cooked for 4.2 or something. Then I tried to use all the files which are in the official repo https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174/hw3.0 (recommended by http://www.killernetworking.com/support/knowledge-base/17-linux/20-killer-wireless-ac-in-linux-ubuntu-debian). Magic doesn't match.

Since I'm in the beginning of an installation, restart is not an option for me, that's a 22 catch. Instead I wrote a little script which modprobe -rs ath10k_pci, ath10k_core, ath, mac80211 and cfg80211. Another script insmods these in reverse order.

I also tried board-2.bin by https://github.com/kvalo/ath10k-firmware/pull/3. Magic doesn't match.

Little more info. Initial/original state of the installer's /lib/firmware/ath10k/QCA6174/hw3.0 firmware directory:

-rw-r--r-- 1 root root   8124 Mar 21 12:27 board.bin
-rw-r--r-- 1 root root 733784 Mar 21 12:27 firmware-4.bin

One of my tries which looked promising by the dmesg without firmware crash, but could not init core:

Mostly I get firmware crashes in dmesg. I'll try the deb package soon.

Note: it's very important to check each time you boot that the BIOS didn't revert back from UEFI-CSM mode to UEFI. Apparently this proved to be crucial for the install, without CSM the install just silently stalls. Also check if the BIOS didn't revert back to Secure Boot mode. What a headache!

Upgrading the v1.157 firmware package to 1.158 helped (I didn't need to swap out any of the files from the 1.158 deb). Details:

  1. First I stopped the network:

    sudo su
/etc/init.d/Network-Manager stop
/etc/init.d/Networking stop

  2. Unloaded the kernel modules:

    modprobe -r ath10k_pci
modprobe -r ath10k_core
modprobe -r ath
modprobe -r mac80211
modprobe -r cfg80211

  3. Upgraded the firmware package

    dpkg -i linux-firmware_1.158_all.deb

Content of the firmware directory after that:

-rw-r--r-- 1 root root 271412 May  6 12:42 board-2.bin
-rw-r--r-- 1 root root   8124 Apr 25 12:59 board.bin

dmesg:

[ 1084.393020] ath10k_pci 0000:04:00.0: pci irq msi-x interrupts 8 irq_mode 0 reset_mode 0

[ 1086.830651] ath10k_pci 0000:04:00.0 wlp4s0: renamed from wlan0

So we finally have wlan0 (renamed to wlp4s0)

  1. Loaded the kernel modules

    cd /lib/modules/4.4.0-21-lowlatency/kernel/
insmod net/wireless/cfg80211.ko
insmod net/mac80211/mac80211.ko
insmod drivers/net/wireless/ath/ath.ko
insmod drivers/net/wireless/ath/ath10k/ath10k_core.ko
insmod drivers/net/wireless/ath/ath10k/ath10k_pci.ko

  2. Started networking

    /etc/init.d/Networking start
/etc/init.d/Network-Manager start

  3. Needed to restart nm-applet:

    kilall nm-applet
nohup nm-applet &

Now I could install mdadm. If I complete my next mission objective, I'll finally be able to install Linux: How to determine device name for NMVe SSDs during install

Just FYI, current state with Ubuntu 17.04 is (error, error, error...):

    Please try the newer firmware package. With a working internet connection, please open a terminal and do:

    wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.161.1_all.deb
sudo dpkg -i linux-firmware*.deb
sudo modprobe -r ath10k_pci && sudo modprobe ath10k_pci

    Your wireless should now be working.
