David Ayers, thank you for reporting this and helping make Ubuntu better. Please execute the following command, as it will automatically gather debugging information, in a terminal: apport-collect 899009
As well, since you identified this being a regression, the next step would be to perform a kernel bisect. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? ** Tags added: needs-upstream-testing regression-release ** Description changed: I'm using Maverick on a day to day basis on this HP Presario CQ61 and I have also tested Natty via a USB-stick installation. Both have good wireless connection behavior. Yet when testing Oneiric via A USB-stick installation the wireless connection is has extreme latency issues. For example, using scp to copy the initrd via Natty or Maverick takes about 7 seconds on my network, where Oneiric quickly stalls at about 10% and takes minutes before reaching 11% after which I abort. Also access vie NFS stalls, surfing has long latencies as does any other network transfer. There's nothing suspicious [for me] the dmesg or syslog and ifconfig does not report dropped packages. - I'm not sure how I would gather more meaningful information. + WORKAROUND: Turning off the hardware encryption works around the issue + for me: + + sudo -s + echo echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf + + reboot ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: linux-firmware 1.60 ProcVersionSignature: Ubuntu 3.0.0-13.22-generic 3.0.6 Uname: Linux 3.0.0-13-generic x86_64 ApportVersion: 1.23-0ubuntu4 Architecture: amd64 Date: Fri Dec 2 09:20:55 2011 Dependencies: - + EcryptfsInUse: Yes InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) PackageArchitecture: all ProcEnviron: - LANGUAGE=de_AT:de - PATH=(custom, no user) - LANG=de_AT.UTF-8 - SHELL=/bin/bash + LANGUAGE=de_AT:de + PATH=(custom, no user) + LANG=de_AT.UTF-8 + SHELL=/bin/bash SourcePackage: linux-firmware UpgradeStatus: No upgrade log present (probably fresh install) ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/899009 Title: extreme network latencies with ath9k on HP Presario CQ61 on oneiric To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/899009/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
