Comment 8 for bug 463581

I got tired of the problems with ath5k, such as freezing my computer (90% sure ath5k was the culprit), network manger roaming to none etc. and installed the windows driver under ndiswrapper. Worked like a charm -- why didn't I think of this immediately?

Instructions in the last post in the following thread: http://ubuntuforums.org/archive/index.php/t-429537.htm

Maybe this can be of some help to someone else as well.
