Chili555,
Seems the fw nomenclature bug is still there.

Chili555,
Btw, i do have the device and would be glad to help with testing, should the need arise henceforth.

Haha, Thanks everyone. It fixed my wireless too. I'm using Acer Aspire e5-473g-56k4. Finally found this thread after hours of googling.

Thank you very much for this!!
After following the instructions and copying the firmware I was able to make the wifi work!

However, I'm a bit worried about a kernel upgrade breaking the fix, and having to recompile and reinstall manually again.
This laptop is my father's, and he is not savvy enough to do that by himself, so I was wondering if it is possible to write a command to rebuild the module automatically when a new kernel is installed.

There probably is, but I haven't any idea how to do it. Scripting isn't my area of limited expertise.

You could easily write commands in /etc/rc.local to recompile every time the machine is booted; something like:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

cd /home/poppa/backports-20151120
make clean
make defconfig-ath10k
make
make install

exit 0

However, this will be a bit time consuming, Poppa may complain that it takes three minutes to boot!

You could instead freeze the linux-image package from being updated:

sudo apt-mark hold linux-image-generic linux-headers-generic

I think the best approach is to install a later mainline kernel that includes the driver and won't be updated by Update Manager.

If you need a step-by-step, post back and I'll be happy to help.

Hello.

I have an Acer Aspire E5-574G-57ZD.

I have been trying to install Ubuntu for almost a month now. Ubuntu is working fine, Wlan is not. .


I have followed the advice given in the first 10 answers to this thread.


When I type:

dmesg | grep ath


There is no output.


Yet I still do not have wlan, even after a reboot.


Please, could anyone help me?


Thanks a lot

The thing is, I had it working on the bootstick yesterday by following first your post and then afterwards
http://askubuntu.com/questions/70135...o-with-14-04-3

But I then had to use another bootstick for installation.

With this one I tried what is in the link first, to no avail.

I do not seem to have the firmwareproblem though, as I am not getting these errors.

Now I am sorry I wrote this post.

I followed through with the post I linked and then with what you recommended and now it works like a charm.
So do not trouble yourself over my post.

This is Acer Aspire E 5-574g-57ZD



And thank you thank you thank you so much for these posts!
