The patch in https://bugzilla.kernel.org/show_bug.cgi?id=6#c22 is really a workaround that limits tx rates to avoid overheat at high rates, but is not going to be a solution for upstream for a number of reasons. It's intended for a workaround for the self built kernel (I can build this for you?) but expect it's temporary in nature. The last patch they have is trying to gather more information on why the firmware is crashing.. I'm curious if there is some problem in the firmware that should be monitoring the device temp and failing to take action on to avoid this issue they are trying to get a handle on. Saddly I don't have access to the firmware source to be able to do that. I could also build a kernel for you that would include the firmware crash dump we could feed back to the kernel bug developer in hopes of helping them isolate the issue. I don't have your device to test with, are you willing to help debug the issue if you could get kernel builds?

@Oleksij, it appears tougher to locate than I thought. I'm back to kernel 3.11.0-15-generic. I tried to overheat by stressing the CPU, GPU and wireless device for 15 minutes by running stress --cpu 4, glxgears fullscreen (vsync on however) and setting txpower to 20 and pingflooding my gateway (sudo ping -f -s 1476 ). It did not succeed. Only after 6-9 hours of moderately (ping -Di 0.2 -s 65507 192.168.1.1, you'll be the judge) pingflooding my gateway I got into this state where I could not ping my gateway anymore. Stopping the ping flood, waiting a while and trying a normal ping again did not appear to work. Only after suspending, waiting a while and resuming I can get the wifi adapter to function again. Resuming 1-2 seconds after suspending did not work for me. However, after this suspend-resume trick I can trigger the nonfunctional state quite easily after 10-15 minutes. So I am a bit confused about whether this is related to overheating, if it takes such a long while to trigger. Can I enable some kind of debugging to show this behaviour? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1049383 Title: ath9k_usb: TL-WN821N v3 (AR7010+9287) Connection drops To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1049383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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 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.

I've just found a link(https://bbs.archlinux.org/viewtopic.php?id=136928) that hinted at the possibility of device overheating and suggested reducing the transmission power. I made a test after doing iwconfig wlan0 txpower 10 with a 4GB torrent and managed to download 3GB before the connectivity dropped and I had to replug the device. Still, it's strange as in Windows there's no such issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1049383 Title: ath9k_usb: TL-WN821N v3 (AR7010+9287) Connection drops To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1049383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
