["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

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.

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).
