Version with 3.20 Kernel?(Qualcomm Atheros QCNFA344 Support)

Postby specialdune » Fri Mar 20, 2015 7:17 am

Hi,

so far I found that on my new Acer Aspire VN7 the current wlan chip is not supported,
but it will be with kernel 3.20 which will be released in Q2/2015

So my question is when will there be a linux mint version comming with this kernel?
Or is it possible to get this driver support to linux mint without the new kernel?

A lot of things are possible, but let's take a closer look at your system first.

Please generate an overview of your system like this:
- launch a terminal window and make it fullscreen, to avoid chopped lines;
- copy/paste this command into the terminal:

Code: Select all

inxi -Fxz

(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

BTW:

Next to the Intel Graphics Card there is also a NVIDIA GeForce GTX 850M, but the system tells me that there is no additional driver and installing nvidia-current breaks the display but this is not my main focus so just an additional information about my system. WLAN is much important.

OK, this looks indeed like a driver issue. First try the easy generic solutions: install the latest kernel from the 3.13 series:
https://sites.google.com/site/easylinux ... el-updates
(item 1.2.3, left column)

Then reboot.

When no improvement: install the latest kernel from the 3.16 series. Then reboot.

If these generic measures don't help any, please report back.

P.S.: you might be able to solve the nvidia problem by means of the mamarley PPA:

Your card needed Ath10k module, information is here .
But , there is no backport for kernel 3.13. You can see available backport here.

Note : this method maybe not success and can breaking your installation. I didn't recommended it. The safe way is purchase a cheap wireless usb adapter who works in kernel 3.13 and wait until ath10k is back ported in ubuntu repo. . Last time i use backport a years ago and it give me a headache.

Open update manager and select view>linux kernel , drop down a list and select the latest kernel possible ( at this time is 3.16.0-31 ) and press install the 3.16.0.-31 and reboot . You can check the kernel in use with terminal command :

Code: Select all

uname -a
. From my experience this process is still safe . Also you can check if your wifi card is working or not.

If not working, download and install backport for kernel 3.16 and follow the guide here. As i mentioning above is risky process.

Thank you guys,

but I already did those steps in the exactly same way. So the support will be there in kernel 3.20, hope it will be possible to use it with the current mint version. Or I have to wait till a version which uses this kernel.

You might try this:

Code: Select all

sudo apt-get install linux-firmware linux-firmware-nonfree

Then reboot.

I think the Linux kernel version will be 4.0 instead of 3.20 and this is from the patch that will enable your device

The QCA6174 in combination with new wmi-tlv firmware is capable of
multi-channel, beamforming, tdls and other features.

This patch just makes it possible to boot these devices and do some basic stuff
like connect to an AP without encryption. Some things may not work or may be
unreliable. New features will be implemented later. This will be addressed
eventually with future patches.
