wifi adapter not resumed after hibernate

[Séverin Lemaignan]

After resuming an hibernation, my wifi adapter doesn't show up anymore when I type "ifconfig". Thus, no wifi connection. I'm using an Intel 3945ABG wifi adapter on an ASUS A7J laptop. The ipw3945 module is loaded. If I unload and reload the module, "dmesg" says:

[30242.124000] ipw3945: Radio Frequency Kill Switch is On:
[30242.124000] Kill switch must be turned off for wireless networking to work.

The "kill switch" is however "on", and, actually, if I reboot my laptop, I work flawlessly again.

Thanks for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description doesn't yet have enough information.
Please include the following additional information, if you have not already done so (please pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command 'uname -a' in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command 'dmesg > dmesg.log' and attach the resulting file 'dmesg.log' to this bug report.
3. Please run the command 'sudo lspci -vvnn > lspci-vvnn.log' and attach the resulting file 'lspci-vvnn.log' to this bug report.
For your reference, the full description of procedures for kernel-related bug reports is available at https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks in advance!

Thanks, Brian, for your answer.

Here are the infos you asked for :
Linux skadge-portable 2.6.20-15-generic #2 SMP Sun Apr 15 07:36:31 UTC 2007 i686 GNU/Linux

Now, you know everything about me :)

I'm getting the same problem on my Asus S6F laptop, with one significant difference. Mine isn't fixed by a reboot. The only way I have been able to resolve this is to reboot from a 6.10 live CD and then reboot back into 7.04.

The output from uname -a is "Linux archiegemmill 2.6.20-15-generic #2 SMP Sun Apr 15 07:36:31 UTC 2007 i686 GNU/Linux"

I have attached the output of "lspci --vvnn" and dmesg, taken from

1) before the hibernate,
2) after the hibernate,
3) after a reboot
4) after a reboot with the 6.10 live CD and then reboot into 7.04

Don't hesitate to let me know if there is more information I can provide to help get to the bottom of this.

Regards,

Dave MacLeod

I'm running a stock Feisty install on am IBM Thinkpad T41, with an atheros-based wifi card, and I have exactly the same problem, although for me a reboot works fine.

After hibernation the wifi seems to be trying to connect but failing, making me think this might be a network-manager problem?

[Brian Murray (brian-murray)]

mrben could you please submit a separate bug as your laptop contains different hardware? Thanks in advance.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

As of today, Jan 7, 2009, I am having the same issue: wireless adapter is undetected after resume from hibernate, the only workaround for me is reboot; however, it is odd that it only happens in my desktop with USB wireless adapter (linksys WUSB54G). My laptop pc using Intel internal wifi card is completely fine.

[Leann Ogasawara (leannogasawara)]

touareger, care to open a new bug report? The reason I say this is because you have a different wireless card than the original bug reporter. Even though you may be experiencing the same issue, it really is likely hardware specific.

Séverin Lemaignan, since you are the original bug reporter, can you comment if this is still an issue with Intrepid Ibex 8.10? Thanks.

Hello!

Actually Suspend and Hibernate just do not work on my laptop with Intrepid. So I can not say... sorry!

[Leann Ogasawara (leannogasawara)]

Hi Séverin Lemaignan,

Thanks for the response. Sorry to hear the issue has become a bit worse :( Would you be willing to test the latest pre-release of Jaunty 9.04 (currently Alpha3) - http://cdimage.ubuntu.com/releases/jaunty/ . It contains a newer 2.6.28 based kernel. You should be able to at least test suspend (not hibernate) via a LiveCD. Thanks.

[Andres Mujica (andres.mujica)]

Séverin, i'm closing this bug report ass Won't Fix, mainly because the IPW3945 module was deprecated by upstream some time ago (http://ipw3945.sourceforge.net/)

So if your suspend/hibernate problem is caused by the ipw3945, or if you're still using ipw3945 please migrate your system to iwl3945. Check this page for reference (take into account is a bit old, so it doesn't apply completely but you can use it as a guide).

Also if you're still having trouble with suspend resume, please check https://wiki.ubuntu.com/KernelTeam/SuspendResumeTesting/Feedback and look for your test results for your model. If not there, please check https://wiki.ubuntu.com/KernelTeam/SuspendResumeTesting and open a new bug as described there.

Thanks in advance !!

[Séverin Lemaignan (skadge)]

Hello! Thanks for the commitment!
I, of course, migrated to iwl since a couple of Ubuntu version.

The suspend and resume still doesn't work with Jaunty, but we can definitely close this bug report :-)
