Last modified: 2013-02-13 11:06:53 EST
Description of problem:
Quoted from Bug 805285, where I was told to file this separately:
I've noticed that with iwlwifi.wd_disable=1 using kernels 3.3.0-4.fc16.x86_64
and 3.3.0-8.fc16.x86_64, I get a different kind of disconnection problem,
sometimes very frequently, sometimes not. dmesg says:

Is the fact that it's setting the regulatory domain to DE unusual since I'm in

Steps to Reproduce:
1. Use the wifi for a while.
The wifi connection stops working, though it still shows up as connected in NetworkManager.
The wifi connection should continue working.
My laptop is a Thinkpad W520.

# Mass update to all open bugs.
Kernel 3.6.2-1.fc16 has just been pushed to updates.
This update is a significant rebase from the previous version.
Please retest with this kernel, and let us know if your problem has been fixed.
In the event that you have upgraded to a newer release and the bug you reported
is still present, please change the version field to the newest release you have
encountered the issue with. Before doing so, please ensure you are testing the
latest kernel update in that release and attach any new and relevant information
you may have gathered.
If you are not the original bug reporter and you still experience this bug,
please file a new report, as it is possible that you may be seeing a
(Please don't clone this bug, a fresh bug referencing this bug in the comment is sufficient).
I've not had this happen with 3.6.2-4.
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '16'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 16's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 16 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" and open it against that version of Fedora.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
