Bug description:
Hi,

I updated to jaunty yesterday and want to report on wifi problems. running newer atheros chips with ubuntu was always difficult but IMO intrepid and ath9k solved these kind of issues more or less. surprisingly they are back in jaunty (rc1) now. my connection is very weak which especially affects surfing, in fact you always have to reload a page several times to get it working. the connection always stops for some seconds (!) before it works again, see ping example below. maybe this corresponds to the comment on another bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/342802/comments/5 (however in my case it only disconnects very rarely).

i was using ndiswrapper in 8.04 but ath9k since 8.10.

modprobe wl results in:
...@simbox:~$ sudo modprobe wl

anyway, thanks for jaunty and for putting so much work in to linux making it a great alternative.
