Qualcomm Atheros QCA9565/ AR9565, UBUNTU 12.04

[anoop_n2]

I had purchased a Dell Inspiron 14 3421 LAPTOP, My WiFi details are
Qualcomm Atheros QCA 95665/ AR9565 wireless network adapter[168c:0036] (rev 01).
I have installed Ubuntu12.04 LTS , but WiFi driver is not detected.
I had contacted DELL Support center on phone, They had suggested to install
a genuine Windows version which is only supported by them
Please help me to find out a driver.
Thanks in advance
Anoop

Please check here: http://ubuntuforums.org/showthread.php?t=2103062 Post #1 describes your device, Ubuntu 12.04 and includes the solution.

It worked like a CHARM
Brief of what i did for further reference.

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

https://www.kernel.org/pub/linux/ker...kports/stable/
Downloaded and extracted; compat-drivers-3.9-rc4-2-s.tar.bz2

cd Desktop/compat-drivers-3.9-rc4-2-s
sudo su
./scripts/driver-select ath9k
make


I got one error after this command, the error was
error: redefinition of ‘kref_get_unless_zero’
include/linux/kref.h:47:32: note: previous definition of ‘kref_get_unless_zero’ was here

Then i did this in one of file

open the file .../compat-wireless-2012-12-18/include/linux/compat-3.8.h in your favourite editor,
find the kref_get_unless_zero function (telling from your error message, it should be on line 47) and comment it out. In case you have no idea what I'm talking about: Comment this code


static inline int __must_check kref_get_unless_zero(struct kref *kref)
{
return atomic_add_unless(&kref->refcount, 1, 0);
}

then

carry on with

make
make install
exit

after a reboot , my wifi is working like a charm.....

Thanks

Awesome! Great job. You will have compiled the driver for your currently running kernel only. When Update Manager installs a later linux-image, after reboot, re-compile:

cd compat-wireless-3.6.6-1-snpc
sudo su
make clean
./scripts/driver-select ath9k
make
make install
modprobe ath9k
exit

The change to compat-3.8.h need not be repeated.

I have the same problem driver for Qualcomm Atheros QCA9565/ AR9565 is not instaled, but when I perform the quoted commands I get stuck at make command,

This is my first time working in Ubuntu and I'm already stuck

Would you mind just confirming a few things?

lspci -nn | grep 0280
sudo dpkg -s build-essential | head -n5

[chodislav]

choda@Lappy:~$ lspci -nn | grep 0280
08:00.0 Network controller [0280]: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter [168c:0036] (rev 01)

choda@Lappy:~$ sudo dpkg -s build-essential | head -n5
[sudo] password for choda:

I disabled wireless connection in upper right corner and since then I don't have option to enable it again.

While looking for solution on internet I found this command, maybe it can help..

Thanks for help

I may have found it! In the changelog for 3.6.8 here:

compat: Backport kmalloc_array()

Therefor, please try to compile this package instead: http://www.orbit-lab.org/kernel/comp...1-snpc.tar.bz2

[chodislav]

Nope, that file won't do the trick

Greater love for the forum hath no Chili than he installeth 12.04 LTS on an old harddrive and compile the driver. It compiles for me with a couple of warnings and NO errors. I am mystified.

May I assume you did do this step before you did 'make?'

./scripts/driver-select ath9k

If you didn't or you are unsure, please do:

cd /home/choda/compat-wireless-3.6.8-1-snpc
make clean
./scripts/driver-select ath9k
make
sudo make install

Weird.
