Wifi network is secured (WPA2-PSK AES only).
No MAC Filtering.
Firewall is active from the setup of my wireless router.
cant access beacon interval on my router.

Status changed to 'Confirmed' because the bug affects multiple users.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.7 kernel[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.

Hi Mr Salisbury,

as you've ask me to do, I've made some tests with the latest kernel :

linux-headers-3.7.0-030700rc2-generic_3.7.0-030700rc2.201210220428_amd64.deb
linux-image-3.7.0-030700rc2-generic_3.7.0-030700rc2.201210220428_amd64.deb
linux-image-extra-3.7.0-030700rc2-generic_3.7.0-030700rc2.201210220428_amd64.deb

but the issue, still exist with the latest kernel.

I've stayed connected for about an hour, and i've get disconnected, and i can't connect on wifi, but ethernet stills works (as always).

This latest kernel is very (very) laggy for a daily use, and eats all cpu cycles for Xorg.

Thanks for your help and support.

[guillaume le louet (guillaume-lelouet)]

Hello. I think I am affected by this bug too. My wifi just disconnected with no reason, and then I saw the networks but I could not reconnect, it kepts asking me the wifi passwords..

Whenever I suspend my laptop to RAM, I am nearby assured I won't get a working wifi chipset at the wake up. This bug's been here for like a year for me. Only recently did it start to disconnect on normal user sessions.

[penalvch (penalvch)]

guillaume le louet, if you have a bug in Ubuntu, could you please file a new report by executing the following in a terminal:
ubuntu-bug linux

For more on this, please see the Ubuntu Kernel team article:

When opening up the new report, please feel free to subscribe me to it.

Please note, not filing a new report may delay your problem being addressed as quickly as possible.

Thank you for your understanding.

[penalvch (penalvch)]

Joel Chav, 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, 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-v3.7-rc8

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.

Hello everybody,

I've got a single disconnection of wifi since i've update my kernel. Still making tests on that issue.

Thanks again for your help.

Joel Chav, thank you for testing mainline kernel v3.7-rc8. Could you please test http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/ ?

I will give you an update about wifi disconnecting.

Thanks.

Joe

[Joel Chav (cdljoel)]

Sorry,

This PPA release does not fix that bug for me.

I've found on ubuntuforums.org a way to track why wifi is stuck (it seems to be solved for some users at least) :

http://ubuntuforums.org/showthread.php?t=1962191

Today i've succeed to reconnect wifi

joe@Mediacenter:~$ rfkill list all
0: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: no

next time i will try again while it disconnects for seeing if i've got an clue to fix that issue.

Thanks again.

Joel Chav, thank you for testing the mainline kernel. Could you please test http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-rc1-raring/ ?

[Joel Chav (cdljoel)]

Hello everybody,

Since kernel-ppa i've no longer need to reboot my computer to activate wifi, only thing needed is to deactivate and reactivate wifi.

That's an improvement (for me), no longer need to connect an ethernet cable while wifi disconnects ...

About rfkill, it seems there is no soft / hard lock on wifi while it disconnects.

Hello Everybody,

Just end to migrate from 12.10 to 13.04. And i've noticed that the issue i've reported is still present ... and not yet resolved.

Less often than it used to be but still happens sometimes.

Sorry Christopher i've ain't see your last message until today. Yes I've update my bios to the latest (no bios update since august 2010). But as i've said before, the problem happens when i've migrate from 12.04 to 12.10.

Hello everybody,

Thanks for your support Christopher.

What do you want me to do? Just use the live image on usb and act as usual?

Nothing else?

I'll be back soon with update ...

Thanks again.

Hello Christopher,

Since a recent update i've noticed a few enhancements and improvements on Ubuntu 13.04.

I've made a try on the latest beta and no disconnections have occured thru my usage ...

Hope the best is going on ....
