Comment 44 for bug 783582

And hoping I can be forgiven for trashing this thread with other fixes related to the new Acer Aspire models, making sure you have a file /etc/modprobe.d/ath9k.conf containing "options ath9k nohwcrypt=1" does magic for the wifi performance as well. All these three "Kinder-egg" of fixes (three fixes in one thread; audio, brightness and wifi) two days before I had to bring my laptop on vacation! Looks like there will be code written this vacation after all. Thanks to everybody.
