Acabei de instalar o 16.04 no meu Aspire E 15 (E5-573-35Q3)
Eu tenho uma Qualcom Atheros mostrada pelo seguinte:
$ lspci -vvnn
03:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:0042] (rev 30)
Subsystem: Lite-On Communications Inc Device [11ad:0806]
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 0, Cache Line Size: 64 bytes
Interrupt: pin A routed to IRQ 50
Region 0: Memory at b0400000 (64-bit, non-prefetchable) [size=2M]
Capabilities: <access denied>
Kernel driver in use: ath10k_pci
Kernel modules: ath10k_pci
Para instalar os drivers, segui o seguinte, como fiz com os anteriores disros:
sudo apt-get install build-essential linux-headers-$(uname -r) git
echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf
wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v4.4.2/backports-4.4.2-1.tar.gz
tar -zxvf backports-4.4.2-1.tar.gz
cd backports-4.4.2-1
make defconfig-wifi
make
sudo make install
Tudo funciona bem, exceto o "make install". Eu recebo mensagens de gazillion como as seguintes:
INSTALL /home/cecil/backports-4.4.2-1/compat/compat.ko
At main.c:222:
- SSL error:02001002:system library:fopen:No such file or directory: bss_file.c:175
- SSL error:2006D080:BIO routines:BIO_new_file:no such file: bss_file.c:178
sign-file: certs/signing_key.pem: No such file or directory
que são repetidos para cada .ko que deseja instalar (123 deles)
Então diz:
sign-file: certs/signing_key.pem: No such file or directory
DEPMOD 4.4.0-21-generic
depmod will prefer updates/ over kernel/ -- OK!
Note:
You may or may not need to update your initramfs, you should if
any of the modules installed are part of your initramfs. To add
support for your distribution to do this automatically send a
patch against "update-initramfs.sh". If your distribution does not
require this send a patch with the '/usr/bin/lsb_release -i -s'
("Ubuntu") tag for your distribution to avoid this warning.
Your backported driver modules should be installed now.
Reboot.
Eu então busco o firmware com:
git clone https://github.com/kvalo/ath10k-firmware.git
sudo cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k/
sudo cp /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin
que parece rodar bem, mas quando eu reinicio - ainda não há wifi detectado.
Isso é um bug na nova distro, ou devo fazer outra coisa?
Obrigado

Eu corri dmesg |grep ath - não encontrei nada
Eu corri lsmod |grep ath - não encontrei nada
Eu tentei carregar com sudo modprobe ath10k_pci
entendeu a mensagem:
modprobe: ERROR: could not insert 'ath10k_pci': Required key not available
Eu tentei o modprobe -r ath10k_pci apenas no caso, mas ele não encontrou para removê-lo.
OK - eu removi a bagunça que fiz ao tentar instalar um driver ath10k_pci:
sudo make uninstall (in the backports.... directory)
Eu então reinicializei - o lsmod encontrou os drivers agora instalados:
ath10k_pci 45056 0
ath10k_core 311296 1 ath10k_pci
ath 32768 1 ath10k_core
mac80211 737280 1 ath10k_core
cfg80211 565248 3 ath,mac80211,ath10k_core
dmesg|grep ath encontrou muitas informações sobre o firmware que eu deveria precisar. Você poderia, por favor, traduzir: -)

AHA - Eu acho que é fixo.
Eu vejo que a distro não tinha drivers QCA9377.
Eu então baguncei as coisas tentando compilar as minhas. Uma vez que
bagunça foi desfeita, em seguida, copiando os drivers QCA9377 para / lib / firmware ... o sistema agora encontra o driver correto e Walllaaaa!
Graças a chilli555 - o problema está resolvido!
