Quantal A2 failed to automatically connect Centrino Wireless N

[jerrylamos]

Wireless WPA was working this morning with varying delays from 30 seconds to a couple minutes when I connected manually with systems settings network.

This evening booting cold after 12 minutes still no automatic connect. (After 10 minuties I had booted Acer Aspire 5253 with Broadcom, Quantal A2, connected automatically right away proving network O.K.)

At 12 minutes or so, did ubuntu-bug network-manager. When it asked to send report, I selected systems settings network. Sluggish response, for example 28 seconds to connect even after it found the network name.

Finally up and running, hardly what I'd call connect automatically. Kernel 3.5.0-2 must be having a problem with Centrino wireless N that it does not have with Boradcom.

Is there any way to trace what 3.5.0-2 is doing after cold boot that it does not connect automatically?

Bug #1015096 is related, that was with kernel 3.5.0-1 when it was very difficult to get connected at all.

Thanks, Jerry

Hi, jerrylamos,
I thing that you report against the wrong package. It seems to be not the network manager by itself it is more a problem with the kerneldriver.

I swithc the package to that.

[Brad Figg (brad-figg)]

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1019083

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[jerrylamos (jerrylamos)]

sudo apport-collect 1019083
ERROR: The launchpadlib Python module is not installed. This functionality is not available.
jerry@Aspire-5253:~$ sudo apt-get install launchpadlib

Tried both apport-collect and sudo apport-collect they wouldn't run. What package(s) are needed?

On both netbook and wide screen notebook with wireless WPA almost always have to manually connect to hidden wireless even though wireless is checked enabled, connect is checked automatically, and when I connect manually the menus already have the network name and password.

What do I install to get apport-collect to run?

Thanks, Jerry

[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 v3.5kernel[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(Only that one tag, please 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.

[jerrylamos (jerrylamos)]

Installed latest upstream kernel as in your directions

Distributor ID: Ubuntu
Description: Ubuntu quantal (development branch)
Release: 12.10
Codename: quantal
Linux Aspire1 3.5.0-030500rc5-generic #201206302035 SMP Sun Jul 1 00:43:03 UTC 2012 i686 i686 i686 GNU/Linux

First boot from shutdown, "Disconnected".

Wait 1 minute, nothing

Systems Settings Network response quite sluggish, example on selecting "Connection" takes 30 seconds
Menu already has WPA password, mouse click
16 seconds later "Connect" message.

Shutdown, rebooted, same thing all over again. First thing on boot does "Disconnect" and does not enable wireless and does not connect automatically, and is quite sluggish in responding to menu.

Now I do have partitions with Maverick and Precise as well as a couple Quantal's if they would be useful to try.

My opinion, upstream no better than latest 3.5.0-3 Quantal kernel on wireless WPA
Intel Corporation Centrino Wireless-N 1000 with Intel driver.

Let me see if I can set the tags as you suggest.

Jerry

[jerrylamos (jerrylamos)]

Turned the "confirmed" tag on, I couldn't find the 'kernel-bug-exists-upstream' tag.

Thanks for your attention.

Jerry

[jerrylamos (jerrylamos)]

Turned the "confirmed" tag on, I couldn't find the 'kernel-bug-exists-upstream' tag.

Thanks for your attention.

Jerry

BTW, Precise may disconnect when the applet comes on, but seconds later "connects automatically" no manual manus required.

[Sasa Paporovic (melchiaros)]

Simple copy paste in the tag line for adding tags. Sometimes there is no auto suggestion.

I have removed "needs-upstream-testing".

[jerrylamos (jerrylamos)]

Thanks. Quite a contrast having to manually connecting to wireless WPA between the Intel Centrino with Intel driver with Quantal even taking 30 to 40 seconds to respond to "Connection" mouse click

versus automatic connection with Precise same hardware

and versus automatic quick response with Acer Aspire widescreen notebook on Quantal.

Any idea why the "automatic" code is not being evoked or is stuck?

Thanks, Jerry

BTW, I think I saw a comment that Phillinux has a Centrino but I don't know if he's using wireless WPA.

[Joseph Salisbury (jsalisbury)]

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.

Did not automatically connect from cold start today. Attached whole dmesg to bugzilla 44291. Ed of dmesg copied below.

Note 3 minute wait after boot for connect. Gave up at that point and selected "systems settings > network".
What is the "DENIED" message? What is "epollwakup" and if it is what it seesm, why wasn't it issued at boot?
Note also took over a minute for "systems settings > network" menu to finally complete.

Thanks for any thoughts. Jerry

[Sasa Paporovic (melchiaros)]

Jerry could you please copy paste the link from kernel bugtracker here(full). The link from comment 12 only points on launchpad itself.

[jerrylamos (jerrylamos)]

https://bugzilla.kernel.org/show_bug.cgi?id=44291

I think that's it, copied it from the URL when I was viewing the bug.

Jerry

[Sasa Paporovic (melchiaros)]

In principle yes, but when you not post the full URL launchpad link automatically to a launchpad bug of this number.

By the way, I have looked at the kernel bugtracker ticket. You should set back the "Needinfo" entry to "New" when you have provided the needed information.

[Sasa Paporovic (melchiaros)]

I have linked the bug from kernel bugtracker here. There will be automatically imports of all comments you are doing there. So, bughandling should be primary on kernel bugtracker.

[Sasa Paporovic (melchiaros)]

Please also change in kernel bugtracker the kind of attachmend to text. In moment the dmesg are handeled as bin

[jerrylamos (jerrylamos)]

Comment #18 - they are text. I have no idea why bugzilla marks them as bin.

I downloaded one by selecting it and did a save file.

I selected the saved file and I could read it fine with the normal Nautilus display.

Jerry

[Sasa Paporovic (melchiaros)]

Yes, you have done all correct, it is a known bugzilla issue. And the method you describe work.

[jerrylamos (jerrylamos)]

In weeks of no "automatic connect" I finally got one. dmesg is attached. It looks a lot different at the end than the other dmesg I have posted.

I'll try later to reproduce the bug or success.

Jerry

[jerrylamos (jerrylamos)]

Here's the dmesg from an actual auto connect. Looks a lot different on the last few lines:
[ 54.914767] EXT3-fs (sdb7): using internal journal
[ 54.914789] EXT3-fs (sdb7): mounted filesystem with ordered data mode

[ 87.143210] wlan0: associated
[ 87.145928] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready

Will try again for success/failure. Takes a shutdown - wait - reboot cycle to do it.

Jerry

[Sasa Paporovic (melchiaros)]

Thank you for going further, but bughandling is now primary on the kernel bugtracker and not so anymore here.

And give them time to handle. It may be weeks. No, good info, I know, but it is like it is. No more developers than threre are, are arround.

[Sasa Paporovic (melchiaros)]

Can you try again to run:

apport-collect 1019083

I would like to look at the logs

When this happends again:

ERROR: The launchpadlib Python module is not installed. This functionality is not available.

please install synaptic and type in launchpadlib in the search form.

there should be a package

python-launchpadlib

install this and make sure(when it is still not working) that

liblaunchpad-integration * (also search from)

is installed(6 packages shown not all needed)

[Sasa Paporovic (melchiaros)]

Please also attach your latest syslog manually. Not the compressed ones.

[jerrylamos (jerrylamos)]

Took over 2 minutes for an "automatic connection".
dmesg and syslog are attached to:

https://bugzilla.kernel.org/attachment.cgi?bugid=44291

Tried apport-collect. Installed launchpadlib.

I'm running an upstream kernel as suggested earlier in this bug. Apport-collect wants an Ubuntu kernel so I'll reboot.

p.s. Problem still prevalent.

[jerrylamos (jerrylamos)]

Upstream thinks this is a Ubuntu problem. Once given the authentication request, the kernel goes right ahead and connects with no retries, they see no problem on their end. See below.

So the question is, why does Ubuntu take so long between these next two lines in dmesg? What is Ubuntu waiting for?

[ 54.117720] EXT3-fs (sdb2): mounted filesystem with ordered data mode
[ 185.982020] wlan0: authenticate with 00:0f:b3:b0:d6:3c

In some cases, I've waited 5 minutes for the authentication request from Ubuntu, never came, so I did manual connect.

Excerpt from syslog showing big gap between 14:01:51 and 14:02:29 approximate time as the gap in dmesg with similar messages. Syslog has two additional lines about not being able to open /etc/crypttab and mounting a udisk:

Jul 9 14:01:51 Aspire1 kernel: [ 53.184095] EXT3-fs (sdb7): mounted filesystem with ordered data mode

Upstream's comment:

--- Comment #10 from John W. Linville <email address hidden> 2012-07-09
17:37:49 ---
I'm sorry, but I don't see any evidence of a kernel problem here.

The kernel has no concept of an "automatic connection". Something in userland
(probably NetworkManager in your case) has to tell the kernel what AP to use.
In every case above, the authentication happens on the first try, followed
immediately by the association on the first try. I don't see any significant
delay being introduced by the kernel, and there are not even any retries. At
worst, the kernel could be taking a while to scan -- but I don't see any
evidence of an abnormally long scan either.

Thanks for any ideas.

Jerry

[jerrylamos (jerrylamos)]

Tried copying in Pangolin's /etc/crypttab. That got rid of the message about not being able to open it. No help.

Still no automatic connect. On restart, notice the syslog time lapse between 16:31 and 18:56 where I gave up waiting and manually selected "Connect to hidden wireless network" which took about a minute more.

Jerry

[jerrylamos (jerrylamos)]

Well, maybe it's designated invalid, it's still giving me fits. Not a showstopper. An anklebiter. We'll see if other people hit it.

I'm not a developer. Looking at it from a "black box" standpoint seems that the "script" is delaying issuing "authenticate" from seconds to minutes....I've no clue what it is waiting for...

Thanks for your attention anyway.

Jerry

[Sasa Paporovic (melchiaros)]

Hi Jerry,

do net hesitate. kernel developers are sometimes are a bit unpatient. Give me some days to find time to look at your files.

------------------------------------------------

Jerry, it is not necessary to write so much over one bug. We have over 98.000 open bugs here and someone must read all that what you write if you write. This needs time that we do not have in common. So, lesser is most more here. When you write less and more specific you increase the probalility that someone look at.

[jerrylamos (jerrylamos)]

Alpha 3 still does not automatically connect, even after waiting minuts. Manually select system settings , drop down menu after drop down mneu, wait 40 seconDs Ubuntu finally issues authenticate kernel connects.
3.5.0-9-generic #9-Ubuntu SMP Thu Aug 9 13:55:19 UTC 2012 i686 i686 i686 GNU/Linux
Workaround. boot, wait a little, no connect, then do:
sudo dhclient wlan0
wait 5 seconds, do Ctrl-c connects O.K. Much faster with less manual entry than usung Ubuntu menus. Dmesg excerpt below shows no activity from time 56 to time 112 when the Ctrl-c was issued then authenticate issued right away. Stll no clue why Ubuntu doesn't automatically issue authenticate to kernel at time 56, or why Ctrl-c causes authenticate to issue.

Since I found similar problems with disconnect on QQ Beta2 on Acer Aspire 1 and Aspire 5253 should I start another launchpad bug?

For bug investigation I'd like to try Precise Network Manager on QQ. Is that feasible?

Thanks.

Interesting. Asus transformesr 10.1" tablet running Android connects to same hiidden wireless WPA network instantly.

[penalvch (penalvch)]

jerrylamos, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (3.16). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.
