Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.5kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. Please only remove that one tag and leave the other tags. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Joseph Salisbury where is a daily directory? I can't see such a directory. I already tried to test kernel v3.6-rc1-quantal [0], but I had to remove it, because of the additional problems caused by that kernel. For example, I can't save documents with gedit, if I use that kernel.

I gave kernel v3.6-rc1-quantal [0] a new try and the problem also exists in this mainline kernel.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

The connection to the wireless network often gets lost and then
reconnects. Furthermore the connection to the wireless network is often
very slow (1 Mb/s). Sometimes after I have reloaded the ath9k kernel
module, I can get a connection to the network and sometimes not.
Sometimes I have to reboot the pc, because I can't get a connection, but
often I can't get a connection after that.

wireless card:
TP-Link TL-WN951N (AR5416 / AR5008 / 168c:0023)

I tested the following mainline kernels.:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4.1-quantal/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4.6-quantal/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-quantal/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc1-quantal/

In those upstream kernel versions the bug is still present.

I had this problem also with Ubuntu Oneiric Ocelot 11.10 and with Ubuntu
Natty Narwhal 11.04, but with Natty the problem was not so bad because
it was very rare.

Sebastian , regarding your comments https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1032826/comments/8 :
>"What additional informations do I need from those sites?:
http://www.kernel.org/doc/Documentation/oops-tracing.txt"

As the problem is one with the ath9k driver but does not produce an oops (ex. flashing Caps Lock), you do not need to provide information from this document.

<"http://www.kernel.org/doc/Documentation/"

I briefly browsed through each document and did not see one that fit for you to provide more information. So, please skip for now and if upstream asks for more information, the Ubuntu wireless debugging article could be updated with the more accurate and recent upstream debugging information https://wiki.ubuntu.com/Kernel/LinuxWireless .

However, could you also please provide any missing information following https://wiki.ubuntu.com/Kernel/LinuxWireless#Bug_Report_Minimum_Requirement_Information ?

I have recently upgraded a system with a TPLink WN951N (AR5416) from 10.04 LTS to 12.04.1 LTS. Under 10.04, I could associate with my wireless AP, although there were periodic hiccups; under 12.04.1, I cannot associate at all. This is true regardless of whether I use the 12.04.1 done via upgrade or via a GRUB2-mounted fresh 12.04.1 ISO. Using an older NIC (abg) under ath5k, I can associate with no problem under 12.04.1. Built-in wireless on the mobo (ralink, abgn) also associates fine under 12.04.1. I have tested the WN951N under 12.04.1 with the built-in wireless on the mobo both plugged-in and unplugged (to test module interference between ralink and ath9k).

In the interest of not becoming a "me too" on this thread, please advise on the proper reporting procedure. Shall I report a new bug on Launchpad? In ath9k-devel? Kernel list? All of the above?

I share Mr. Schlatow's concern about the long-running problems with the AR5416/AR5008 chipset under ath9k. The AR5416 is not an uncommon chipset and this persistent bug represents a substantial loss of functionality for Ubuntu users at all skill levels.

Sebastian Schlatow, while we are waiting for an upstream response:
+ Does the issue occur with different APs?
+ Does compat-wireless provide a WORKAROUND or solution following https://wiki.ubuntu.com/Kernel/LinuxWireless#Compat-wireless_in_Ubuntu ?
+ Does ndiswrapper provide a WORKAROUND or solution following https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper ?

This is a desktop-pc, so I haven't access to other APs.

I tested some versions of "linux-backports-modules-cw-3.3-precise-generic", but no one provided a solution. I don't tested versions from "linux-backports-modules-cw-3.4-precise-generic", because I tested newer kernel versions than the provided backports.

Why should I test compat-wireless, if I test the newest upstream-kernel?

I don't want use ndiswrapper!

Sebastian Schlatow, thank you for testing the newest mainline kernel. Regarding your comments https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1032826/comments/20 :
>"I don't want use ndiswrapper!"

Of course you do not have to. However, it would be a shame if it would have worked for you, while one waits for this bug to be fixed.

Despite this, could you please regression test for this in Lucid via http://cdimage.ubuntu.com/releases/10.04.4/release/ ?

Christopher M. Penalver, you mean a working solution with ndiswrapper would be a fix for this bug?

Is there something special or why you post a link to lucid dvd image? Could I also download the lucid cd image http://releases.ubuntu.com/lucid/ ?

Either a WORKAROUND or solution, as you like.

>"Is there something special or why you post a link to lucid dvd image? Could I also download the lucid cd image http://releases.ubuntu.com/lucid/ ?"

No, it was completely arbitrary. If the Lucid CD works for you, please use this instead.

I tested the following windows drivers:

http://www.tp-link.com/resources/software/TL-WN951N_100505.zip
http://www.tp-link.com/resources/software/TL-WN951N_v1_100421.zip

with Ndiswrapper from the repository and the current test version:

http://downloads.sourceforge.net/project/ndiswrapper/testing/ndiswrapper-1.58rc1.tar.gz

but sometimes my system freezes after loading the ndiswrapper kernel modul. After reboot, my system stops booting.

http://askubuntu.com/questions/193258/unload-kernel-module-before-boot/193262#193262

If the system is not freezed after loading the ndiswrapper kernel modul, I couldn't recognize a working wireless network interface with iwconfig.

Using Quantal this problem does not occour in my wireless with this PCI-ID. That kernel version had something that fixes that bug.

Marlon Costa as you stated there: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1003406/comments/14, you have a different wireless chipset, so please don't comment that the bug is fixed. I tried the Quantal mainline kernels and the bug is not fixed in those kernels. Which mainline kernels I tested, you can see in the bug description above.

I must say that wireless works much better with v3.8-rc6-raring.
Range seems much worse, but once in range, is much more stable.

Can anyone else confirm as well?

Today I tried Ubuntu Lucid 10.04 from LiveUSB. It seems that the problem also exists in Lucid, because I lost the WLAN connection. The system reconnected immediately, but the wireless speed is slow. Until now dmesg shows no error messages.

Sebastian Schaltow, thank you for testing Lucid and Raring. Could you please test the latest upstream kernel available (v3.10-rc3-saucy) 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, 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-v3.10-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.

as chrisboo found out in this thread:
http://ubuntuforums.org/showthread.php?t=1865577&page=191&p=12634850#post12634850

the wifi is working fine with kernel 3.6.11 found here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.11-raring/

seems like there was some regression introduced in later versions..

Hello,

I signed to this bug because I'm facing it with openwrt. It uses kernel 3.3.8 but it might have something backported from next versions.
This also affects, besides openwrt, fedora. Just look for "phy0: Failed to stop TX DMA," on google.
