I've been looking around since yesterday for a fix and tried several fixes to get my wireless ath9k to work on Karmic but in vain
-Tried removing ath from blacklist
-Tried to use wicd
In all cases, the wireless disconnects after something like 10 minutes and I can't reconnect. None of this happens on Jaunty.
So I can't install Karmic because I can't install the language packages nor use it (and I don't have wires everywhere in the house). So I'm stuck with Jaunty.
Other than recompiling the kernel with ath9k, is there any other way?
