http://bugzilla.novell.com/show_bug.cgi?id=551356 Summary: Dropped connections Atheros AR9280 - ath9k driver regression? Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: x86-64 OS/Version: openSUSE 11.2 Status: NEW Severity: Normal Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: maurice@debijl.net QAContact: qa@suse.de Found By: --- User-Agent: Opera/9.80 (X11; Linux i686; U; en) Presto/2.2.15 Version/10.00 Configuration: I'm using openSUSE 11.2 RC1 x86_64 (the GNOME Live CD installed to harddisk). My hardware: Acer Extensa 5630Z laptop, Atheros AR9280 half mini-PCI card wireless A/B/G/N, connected through A or G. I use WPA/PSK encryption. Problem: With Atheros AR9280 the wireless network connection drops often. It's restored in up to 10 seconds. My findings: 1) I don't have these problems with openSUSE 11.1 (also GNOME, x86_64), dual booted on same laptop. 2) It occurs both on 2.4 (802.11g) and 5.8 (802.11a) GHz. I don't use N yet. 3) I tried an Atheros AR9281 (wireless A/B/G - no N): no lockups but performance is not good Reproducible: Always Steps to Reproduce: 1.Install Atheros AR9281 wireless mini-PCI card 2.Connect to wireless network 3.Start surfing and experience long waits, see network manager notifying that the connection dropped and restoring the connection Actual Results: Dropped wireless connection Expected Results: Continous connection -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I don't have the exact model right now, but it's in an Acer Extensa 5635ZG laptop. I can usually surf the Internet without any bigger problems but when I start to download anything bigger the connection gets lost. Sometimes it gets back automatically, but sometimes I have to unload/load ath9k. I have tested with latest from http://linuxwireless.org/ with much better results. I have seen the same behaviour both in RC1 and RC2. I haven't tested 11.1 though. /Anders -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

WLAN is definitely more stable than with 2.6.31.5-0.1-desktop. No disruptions so far. To eliminate more variables (it is 2.6.31.5 vs. 2.6.31.9 and "desktop" vs. "default"), I will also recompile 2.6.31.5-desktop with your patch "0001-ath9k-Fix-RFKILL-bugs.patch" applied.

I had lots of skipped tracks when using streamripper in a "medium quality" WLAN environment. With 2.6.32, I have no skips at all since two hours. So the patch made things a little bit better but not perfect. Also the "Scan" in knetworkmanager shows the AP "much nearer" than with your kernel version. Neither the laptop nor the router didn't change its position of course.

Yep, it is known, that 2.6.32 is better in throughput. Nobody from developers knows what made the difference AFAIK.

...

Yes, there is a fix of RSSI reporting in 2.6.32. I'll probably fix that too and close this as upstream bug. Thanks for testing. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The throughput is not only better with .32, it is really unacceptably bad in .31. In the current shape, 2.6.31 is not useable for me. Do you consider to port more/all ath9k fixes back to openSuse's maintenance kernel, or is it even considered to upgrade to 2.6.32? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Could you elaborate on that? I have ar9280 and have the same performance both with .31 and .32. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

My streamripper use case, explained in comment 8, had skipped passages in almost every ripped song. Moving to 2.6.32-41 made all problems completely go away. No problems since one week now. Of course, these are only subjective impressions.

First, 2.6.32 just feels better, but I also had other problems with the old kernel (backlight control) where I hoped that it gets fixed in new versions (which is not unfortunately). Since one week, I use the latest 2.6.33rc6 from Kernel:/HEAD/openSUSE_11.2 and I am quite satisfied with stability and performance. I also saw some changes around ath9k in .32 and .33 which did not reach any .31 version. So the motivation to stick with 2.6.31 was quite low. Again, sorry about that. Nevertheless, as offered in comment 12, I can run some network related benchmarks on request. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
