Well, I've just bought a new laptop with the same wifi chipset and it
doesn't work properly. The connection isn't unstable, but it's even
worse: the system only recognize the wifi interface after suspending the
machine and waking up again. That's so weird but it's the only
workaround I've found so

As far as I'm concerned, everything works fine with 3.11 in Saucy.
I agree with Timo : I think it's another bug, that should be declared and
investigated separately.

Agree this is NOT fixed on 13.10. I had the problem on my zenbook ux31
on 13.04, and resolved it with the advices mentioned in this thread.
But after installing 13.10 a couple of days ago, the problem is back
just as before :(
Linux wim-zenbook 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9
I'm marking this as fixed as it's fixed in a released Ubuntu (13.10),
and the remaining thing would be to port needed patches to older
Ubuntus.
According to Kevin's test it may be that more patches would need to be
backported than the one specified. I'd recommend 13.04 users to upgrade
to 13.10.
I am still having problems after applying the backported patched driver.
I went from my wifi dropping out ~ every 20 minutes (reason 2) with a
reboot being the only way to reestablish a connection to this:

Guillaume: Official/easy enough way to get the kernel modules on top of
your existing (eg. Ubuntu provided) kernel. First, I noticed the patches
talked about were already in the 'linux-next' at
http://git.kernel.org/cgit/linux/kernel/git/next/linux-
Yep, linux-next is a real, great improvement. I took the latest snapshot
from
https://www.kernel.org/pub/linux/kernel/projects/backports/2013/06/18/ +
ran make defconfig-ath9k make sudo make install. Hopefully the
patches will get in soon enough, so that I don't need to rerun the
module building
Upstream bug (https://bugzilla.kernel.org/show_bug.cgi?id=49201) was
marked as Fix Released. I checked that the related fixes are in Ubuntu
13.10 (make sure you're running the latest 3.10 kernel). It should be
useful to test it to find out whether things finally have improved. My
initial take is
Are you sure the patches have been included in the latest 3.10 ? Because their
state is still new on patchwork.kernel.org.
https://patchwork.kernel.org/patch/2696121/
https://patchwork.kernel.org/patch/2718041/
As far as I'm concerned, they have worked really well and improved
dramatically wifi
Ah, thanks Guillaume for correction! I was staring at the disabling of
power management, enabling of minstrel algorithm etc but there was still
more then. So staying tuned as well.

Since last week I've tested a few things that do seem to improve connection
quality and range :
- switching to WPA2 (TKIP) instead of WPA
- switching to a channel with a greater number (from 4 to 11)
- disabling ANI
- disabling power management
I've added in /etc/pm/power.d/wireless :

The v3.10-rc2 kernel is now available. Can folks affected by this issue test

Unduplicating. This is related to bug #945379, but it's not specifically
about this AR9485 problem, and the upstream bugzilla tracker also has
two separate bugs for AR9485 and other Atheros devices.
