walden.jos...@gmail.com, thank you for reporting this and helping make Ubuntu better. Karmic reached EOL on April 30, 2011. Please see this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases
We were wondering if this is still an issue in a supported release? If so, as per http://esupport.sony.com/US/p/model- home.pl?mdl=VPCCW2NFX&LOC=3#/downloadTab an update is available for your BIOS (R0170Y7). If you update to this, does it change anything? As well, once complete, please provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Also, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.10-rc3 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. Helpful bug reporting tips: https://help.ubuntu.com/community/ReportingBugs ** This bug is no longer a duplicate of bug 945379 168c:002b Wireless connection randomly drops -- ath9k ** Description changed: I currently am experiencing issues with the "ath9k" modules present in kernel "2.6.31-20-generic" on Kubuntu 9.10. when using the stock modules included with that kernel my wifeless connection in extremely unstable and disconnects and reconnects frequently. After i installed "linux- backports-modules-wireless-karmic-generic" i have been able to maintain a wireless connection but am suffering from serious speed issues. the speed will drastically spike up and then slow down to taking several minutes to transfer even one MB between the laptop with the Atheros and a desktop wired directly into the router. we have other laptops and various other devices that are able to use the wireless with no issues. - it seems to only be this machine with the AR9285. Any help with this - work greatly be appreciated.
