i just installed the 2.6.34-999 mainline kernel, but the same thing still happens. the same gain calibration timeout error occurs.
can i help with any additional pieces of information? ** Tags added: apport-collected ** Description changed: 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).
