Title:
168c:001c ath5k gain calibration timeout when watching flash video
Status in linux package in Ubuntu:
Won't Fix
Bug description:
i have an Atheros wifi card (ar 5007eg) and since upgrading to lucid
and the kernel that came with it (2.6.31-21, i believe), i'm
experiencing some very strange wifi issues:
- at first, my wifi was very buggy and i got many "noise floor
calibration timeouts" as described in many other bug reports here on
launchpad. i was able to fix this and get a relatively stable wifi
using the backport-modules-wireless package.
- however, i still have stability issues with the ath5k driver that can be
reproduced in the following way:
1. surf the internet for hours without problems
2. start a flash video with more than just a couple of minutes (5min approx)
of length
3. wifi crashes with a bunch of "gain calibration timeout" error messages
4. suspend/resume fixes the wifi connection
5. repeat
what i cant for the life of me figure out is what exactly flash videos
have to do with my problem. i can surf webpages without flash videos
for hours without problems, i can download hundreds of megabytes
smoothly, but when i try to watch a simple flash video on youtube or
on megavideo or whatever, it crashes my wifi after a relatively random
amount of time. sometimes, my wifi keeps working for 10 or 20 minutes
into the video, and sometimes it crashes after only 2 minutes. but in
any and all cases, my wifi only crashes when i watch flash videos.
i'm filing this a new bug because a) there seems to be some connection
between my wifi problems and flash, and b) i get "gain calibration
timeout" errors instead of the many "noise floor calibration timeout"
errors described in most other bugs (which i dont get anymore since
installing the backport-modules-wireless package).
