Edit the file

/etc/modprobe.d/blacklist.conf

and add this

blacklist acer-wmi

or you might have to do the following:

sudo modprobe -rfv ath9k
sudo modprobe -v ath9k nohwcrypt=1

If that works you can make it permanent:

/etc/modprobe.d/ath9k.conf

Add the following line:

options ath9k nohwcrypt=1

Reboot.
