Pin, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, 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 daily kernel folder, but the one all the way at the bottom. 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-v3.12-rc6 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 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. ** Tags removed: ath9k-htc ** Tags added: needs-kernel-logs needs-upstream-testing ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1049383 Title: ath9k_usb: TL-WN821N v3 (AR7010+9287) Connection drops Status in The Linux Kernel: Confirmed Status in “linux” package in Ubuntu: Incomplete Bug description: Hi. The connection with this device is fast and stable, but seems to drop after a certain amount of data has been transmitted. The easiest way to reproduce it is to download something large. I can always reproduce it by downloading a torrent. After about 300-400MB, it seems like the wireless dongle hangs and the connection doesn't work anymore. At this point, network commands such as iwconfig freeze, and it's also impossible to reboot or turn off the computer. However, if the wireless dongle is unplugged and plugged again, everything's back to normal. The module is set with nohwcrypt=1. If this option is not set, the connection drops much faster. Also, I've noticed that the latency is lower with nohwcrypt=1 (using speedtest.net, the latency without hardware encryption is consistently 3 times less).
