Hi,
I bought a new laptop for my son, an Acer Aspire E5-575G-55DE, and
installed Centos 7 on it.
The wireless is:
$ lspci -nn | grep Network
03:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:0042]
(rev 31)
The driver for this is ath10k, so I tried installing kmod-ath10k and
ath10k-firmware from elrepo, but no joy: both of these are too old.
I then installed kernel-lt-4.4.21-1.el7.elrepo.x86_64.rpm .
I also copied the 4 files from [1] into
/lib/firmware/ath10k/QCA9377/hw1.0/ (creating this subdir), and copying
firmware-5.bin_WLAN.TF.1.0-00267-1 as firmware-5.bin :
$ pwd
/lib/firmware/ath10k/QCA9377/hw1.0
$ ll
total 1660
-rw-r--r--. 1 root root 427668 Sep 20 12:24 board-2.bin
-rw-r--r--. 1 root root 8124 Sep 20 12:24 board.bin
-rw-r--r--. 1 root root 605908 Sep 20 12:24 firmware-5.bin
-rw-r--r--. 1 root root 605908 Sep 20 12:24
firmware-5.bin_WLAN.TF.1.0-00267-1
-rw-r--r--. 1 root root 46142 Sep 20 12:24 notice.txt_WLAN.TF.1.0-00267-1
$
I also had to yum install NetworkManager-wifi, I guess it hadn't been
installed by C7 because it could not detect any wireless interfaces.
Now, booting into kernel-lt 4.4.21-1.el7.elrepo.x86_64 , the wifi works!
I am posting this to help others who may have similar hardware, but also
as a question / request: could kmod-ath10k and ath10k-firmware from
elrepo be updated in order to support these newer wifi chips?
Thanks!
Regards,
Nicolas
