Acer (ACER) Aspire e1-472g ubuntu-12.04 install wireless card driver

I bought a more affordable laptop in the previous phase Acer (ACER) Aspire e1-472g, with the Linux operating system, due to work needs to replace the operating system ubuntu12.04, but has been plagued by no wireless network card driver. This problem has finally been solved today, the method is as follows:

1. Check the wireless adapter model:

~$ LSPCI-VNN | grep Wireless

My wireless network card is:

02:00.0 network Controller [0280]: Qualcomm Atheros qca9565/ar9565 Wireless Network Adapter [168c:0036] (rev 01)

2. Install linux-headers-generic andbuild-essential

~$ sudo apt-get install linux-headers-generic build-essential

3. Download the driver file and install:

~$ Sudo-i wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.9-rc4/compat-drivers-3.9-rc4-2-s.tar.bz2
~$ Tar xvf compat-drivers-3.9-rc4-2-s.tar.bz2
~$ CD compat-drivers-3.9-rc4-2-s/
~$ ./scripts/driver-select ath9k
~$ Make then found an error:./scripts/gen-compat-autoconf.sh/home/renjie/downloads/compat-drivers-3.9-rc4-2-s/.config/home/ Renjie/downloads/compat-drivers-3.9-rc4-2-s/config.mk > Include/linux/compat_autoconf.hmake-c/lib/modules/ 3.2.0-77-generic/build m=/home/renjie/downloads/compat-drivers-3.9-rc4-2-s modulesmake[1]: Entering directory '/usr/src/ Linux-headers-3.2.0-77-generic '   CC [m] /home/renjie/downloads/compat-drivers-3.9-rc4-2-s/compat/ Main.oin file included from/home/renjie/downloads/compat-drivers-3.9-rc4-2-s/include/linux/compat-2.6.h:71:0,                  from < command line &GT;:0:/HOME/RENJIE/DOWNLOADS/COMPAT-DRIVERS-3.9-RC4-2-S/INCLUDE/LINUX/COMPAT-3.8.H:49:32: Error: ' Kref_get_unless_ Zero ' redefine include/linux/kref.h:47:32: note: The previous definition of ' Kref_get_unless_zero ' in this make[3]: * * * [/home/renjie/downloads/ COMPAT-DRIVERS-3.9-RC4-2-S/COMPAT/MAIN.O] Error 1MAKE[2]: * * * [/home/renjie/downloads/compat-drivers-3.9-rc4-2-s/ COMPAT] Error 2make[1]: * * [_module_/home/renjie/downloads/compat-drivers-3.9-rc4-2-s] Error 2make[1]: Leaving directory '/usr/src/ Linux-headers-3.2.0-77-generic ' Make: * * * [modules] Error 2 Error resolved: Open

Then continue,

Make
Make install
modprobe ath9k
