Bug Description
This card works really slow, network connection is not usable and sometimes produces a kernel panic.
WORKAROUND: /etc/modprobe.
And added the module parameter:
options ath9k nohwcrypt=1
and in BIOS put Network boot on top of the boot priority list.

Also, on Acer Aspire One 722, you must remember to go to the BIOS configuration and put Network boot on top of the boot priority list or else you'll get random full-system freezes when using wi-fi.
Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.
We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.
You can update to the latest development kernel by simply running the following commands in a terminal window:
sudo apt-get update
sudo apt-get upgrade
If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.
If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.
Thank you for your help, we really do appreciate it.

I no longer need to put network as first boot option but still need the nohwcrypt=1 option for ath9k.

Perhaps it will be helpful to note that, just as Jaime Alberto Silva (jaimealbertosilva) found, turning off the hardware encryt has worked wonders for me., My network performance (as seen from just general use of FF) went from spotty and slow to lightening fast. I was also able to move the network boot from first in the boot order which also leads to faster cleaner boots (especialy when ethernet is plugged in). After much searching and reading about this problem, this simple fix does the trick. To be more specific, I am on a fairly fresh 12.04 with all (as far as I can tell) recommended updates applied. As found on
http://
I first tried these commands:
sudo modprobe -rfv ath9k
sudo modprobe -v ath9k nohwcrypt=1
with functionally great results and then
made it permanent by creating the file
/etc/modprobe.
and adding this line (followed by a <cr> which i'm not sure was needed...)
options ath9k nohwcrypt=1
i then moved the netboot from first in the boot order and all still works great!
just for the record:
rone@ronsAcerUbu:~$ lspci -nnk | grep -iA2 net

Let me know if you need any more info.

Um, never mind about the hopeful comment regarding being able to move the network boot from first in boot order. That seemed to be OK thru multiple test boots including a complete power down/up. But, for whatever reason, the next day the <freezing when Unity started> behavior was consistently back. So I once again moved the netboot to first in the boot order and, several days later, all still seems to be OK.

I had the same issue with a Dell Vostro 3560 with the same card.
I created the /etc/modprobe.
I'm running Ubuntu 12.04 64-bit
3.2.0-32-generic

Testing the Ubuntu 12.10, the wifi was working fine, but I needed to go back to precise due to issues with the video card driver (amd catalyst).
