What kernel are you using these days? Can you confirm the result John
mentioned? Do you think it would be worth pursuing a fix for this in
squeeze, and if so, would you be able to test patches if we provide
them?
Thanks for a pleasant report,
Jonathan

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!

Bug#575229: Wireless performance problems with ath5k driver
Forgot to say, although I don't think it's directly pertinent - I
think I'm currently running a 3.2.something kernel on the laptop in
question (an official Debian kernel)

Good to hear. If you can come up with more details about the
remaining iffyness or a reliable way to test for it, please feel free
to file a new bug.
Returning to this bug (long pauses during a network scan): the squeeze
kernel should install without trouble on sid if you'd like to give it
a try.
Thanks,
Jonathan

Sorry for being dense, but I'm having a hard time figuring out what
the current kernel in squeeze is. Can you point me to a .deb or a
version number I can go scrounge around for in ftp?

Here's the easy way:
echo 'http://ftp.us.debian.org/debian stable-proposed-updates main'
>>/etc/apt/sources.list
apt-get update
apt-get install linux-image-2.6.32-5-amd64
vi /etc/apt/sources.list; # remove the new stable-proposed-updates entry
If you prefer an ftp site, [1] should do it. (The APT way is preferred
because it checks checksums. ftp.us.debian.org is a round-robin alias
for several mirrors not directly controlled by Debian.)

So now I'm in suspense. Did you get a chance to try this?
Curious,
Jonathan
