Bug#575229: Wireless performance problems with ath5k driver
Hi Jonathan, sorry about the slow reply. The situation is definitely
better, and my recollection (it's been a while) is that it did improve
around the 2.6.35 timeframe. I've only ever run unstable so I'm not
sure how much testing I can provide, but if a kernel deb was
installable in unstable I would be happy to give it a shot.
My impression is that the card is still kind of "iffy" for interactive
use - it seems to stutter a lot and that may be related to the network
scanning, but it's good enough that I haven't bothered to pursue
anything further.
Thanks!
