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

I just add a Linksys WPC600n ultra PCMCIA atapter to my Thinkpad.And after Ubuntu download and installed the driver.NM shows it and and connected. Here is how the Linksys and the Intel cards are listed.

Linksys-Broadcom BCM-4321 802.11 a/b/g/n

Intel PRO/Wireless 2915ABG [Galexico 2]Now with the Linksys driver,nm will connect to both at the same time without crashing.
The driver for the Linksys is listed as wl.
Thanks hope this helps.

Yup, this bug very much looks like it's hardware specific. I definitely can't reproduce this on my own systems, but I also don't have one that runs with the ipw2200 or ipw2100 drivers.

I'll try to get to the hardware lab tomorrow and test this more thoroughly on hardware that uses this driver.

If anyone seeing this bug has a way to try and reproduce it on the same system after either replacing the wireless chip, or trying it with a USB wifi dongle (or any other such way that would use different hardware that doesn't rely on ipw2200), that's a valid test as well.

Marking as affecting linux since this is hardware specific and NetworkManager itself doesn't really handle the devices differently. Seems like there may be an issue with how the wireless device's or AP's capabilities are being reported.

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

apport-collect 908380

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.

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the following commands in a terminal window:

    sudo apt-get update
    sudo apt-get upgrade

If the bug still exists, change the bug status from Incomplete to Incomplete. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

Marking importance as high due to the number of duplicates.

Changed to confirmed in linux because it doesn't work with the latest kernel either (at least for me).

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.3 kernel[1] (Not a kernel in the daily directory). 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.

Sorry I can't test the new kernel. I am running Precise from a USB stick.

Can other folks affected by this bug test the upstream kernel mentioned in comment #13

Also, did this issue also happen in prior Ubuntu releases, or is this new in Precise(12.04)?

This is new in Precise. Going to try the upstream kernel now.

Bug is reproducible in mainline kernel (3.3.0-030300rc6-generic).

Hi,
So it seems that my problem I submitted another bug about is not this problem though it has been marked as a duplicate. I'm not 100% sure though.
I tried to connect to a secured wifi during install, and nm-applet crashed, but that network was remembered and set to autoconnect. Every time I tried to launch nm-applet, it crashed when it was about to ask for the password. So I opened 'network connections' from the dash, and deleted all the remembered wifi networks and added mine with data from the iwlist eth1 s command's output. No I'm connected to the network and nm-applet runs, though it crashes when I select another secured wifi to connect to. Also, it doesn't show the signal quality (it looks as if there was no signal), and it doesn't show which network I'm connected to, it just shows 'disconnect' under wifi connections from what I know that I'm connected to something. Also, I cannot select any networks to connect to (see the attached screenshot).

...And now, after selecting another network to connect to, I'm again unable to use wifi, though nm-applet runs.

Sorry for writing such a long comment, hope it helps :)
If the problem described above is not related to this bug, I will open another bug.
Thank you in advance.

Péter describes my scenario also, down to the letter.

Péter, Jayson, you'll need to check at least what wireless device is in use on your system. That's why it's prefered to file a separate bug report, because in case of crashes Apport will pop up and ask you to file one -- this can then be automatically marked as a duplicate. Otherwise, please let us know the bug number for your bug that was marked as a duplicate if you think it shouldn't be.

Hi Mathieu,
My original but was 945311 (https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/945311) and it was filed automatically with Apport, and was marked as a duplicate of this bug. Is there anything else I need to do on my end in regards to my original bug report?

Thanks for all you do!

Jayson, nothing more to do for that bug report, it indeed is most likely the same issue (sound similar from the description) though there is no crash report now since it was marked as a duplicate by Launchpad. It's most likely correct.

Now the steps needed is to figure out why this fails. I haven't actually been able to reproduce this at all because I don't have access to any hardware that has that chip; what needs to be done is probably figure out what kernel version introduces it (e.g. try older versions), then bisect to find where the ipw2200 driver stopped properly reporting capabilities.

It's ipw2200 here, too. I'll try the older kernels tomorrow or something.

#18 Péter Trombitás,

That is an excellent description of my problem as well. I've only tested 12.04 beta1 from a live USB stick, but I have never before had any troubles with wireless in Ubuntu since I started using it in 2008. The ipw2200 driver is used and the adapter is called eth1 but that's been the case since 8.04. I've installed wicd as well and managed to set up a connection without any problems.

The problem seems to be in parsing passphrase.
After I've changed passphrase on m AP (by deleting double '@@' it contained) all works as charm.

Thus my bet is that some characters in passphrase make aplet crash. Can anyone confirm it?

Maybe this bug should be also reviewed in security context?

My password contains only normal small letters, so here it's not the cause
of the problem.

I tried it with an older kernel

~$ uname -a
Linux crow 3.0.0-16-generic #28-Ubuntu SMP Fri Jan 27 17:50:54 UTC 2012 i686 i686 i386 GNU/Linux

And restarted nm-applet. No wireless networks showed up, so I toggled the wireless off and on again, causing nm-applet to crash.

~$ nm-applet

LIBDBUSMENU-GLIB-WARNING **: Translation has an invalid value 'I-->D' for default text direction. Defaulting to left-to-right.
** Message: applet now removed from the notification area

I installed the previous version of network-manager and the applet does not crash anymore, but neither will it show me any available wifi networks. It works using a USB tethered connection to my Android.

The previous version was found in /var/cache/apt/archives/

~$ sudo dpkg -i network-manager_0.9.2.0+git201202161854.8572ecf-0ubuntu6_i386.deb

Alan, this bug was reported in December with a much earlier version of NetworkManager; (network-manager 0.9.2.0+git201112151936.6b31828-0ubuntu1), so it's not likely to be a problem tied to these versions of NetworkManager.

The problem only popped up for me after installing updates a few days ago, which is why I tried a previous version. On that note, I spoke too soon, the applet has now disappeared, though the USB network still works.

Something changed now. I have latest version of Precise daily(03-12).

Now all available Wifis are shown darkgray in the applet and i cannot select one of them.
But i can still create a Wifi connection manually with the desired SSID. After a reboot, i get automatically connected.

Philipp: that is how it has been for me recently. it shows my wireless but I am unable to select it. Manually creating it works. Choosing to connect to a hidden network crashes.

Jools, and so we have gone full circle. What you experience was what I
experienced after which I sent a bug report. This bug report was marked as
duplicate and merged with another one.

Another piece of information: Network Connections crashes if I try to edit
a wireless network's config that has no wireless key set yet. I get an
error message saying:
(this is in Hungarian for me, so I'm not sure what's the original:)
Error preparing the editor
"No agents were available for this request." (This is in English).
Now what does this mean?
I don't seem to be able to connect to my wifi from terminal, either (with
"sudo iwconfig eth1 essid SMC key s:<mypassword>). This can mean though
that I'm using the worng command.

Peter, first completely (including the password) configure your hidden
wifi network connection via 'Edit Connections' in networkmanager.
Once you have done this you can connect via the commandline with: sudo
iwconfig eth1 essid 'your hidden networkname' . This assumes that the
wifi interface is called 'eth1'. If this is not the case substitute
'eth1' with the interface name you found with typing iwconfig in the
terminal.

Peter,
Sorry to hear that it did not work for you. I would file another bug if I were
you.
That is the only way to have experts look at the perticular problem and solve
it before Precise hits the marked.

There's a bit of work that can be done at the NetworkManager level to avoid crashing when this kind of issue happen, so I've filed the task for this now; and there's a package I just uploaded to the ~ubuntu-desktop PPA: network-manager 0.9.3.995+git201203081848.bba834f-0ubuntu1~mtrudel2; which fixes the crashes (but we still need the capabilities fixed at the driver level for encrypted networks to show properly. See https://launchpad.net/~ubuntu-desktop/+archive/ppa ; the packages should be built and ready in a few hours.

Any help with testing this fix and the new package will be very welcome :)

Gracias Mathieu

I installed your update, it is not crashing and I get a prompt telling me that the avaialble wifi network needs a password, but it does not offer a prompt to enter a password. If I try to edit the connection, I get a message that the editor failed to initialize, No agents were available for this request.

PS: the network-manager-applet package is not installed nor avaialable from apt. Might this be the problem?

Well, the package for nm-applet is called network-manager-gnome so you may want to check the version for that one. Perhaps the update wasn't ready yet as it was uploaded later than nrtwork-manager.

Sucess!

Enabling the ~ubuntu-desktop PPA, installing network-manager-gnome (and network-manager) from there and restarting allowed me to edit the connection and enter the WEP password. Enough of a workaround for me...

Please confirm the version for network-manager and network-manager-gnome, and also attach a screenshot of that notification if possible. Also, have you rebooted after updating?

This bug was fixed in the package network-manager - 0.9.3.995+git201203081848.bba834f-0ubuntu1

After installing the fix, crashes when selecting predefined wlan are gone, but the panel icon still shows disconnected all the time. Also, all the predefined wlan access points show full signal strength (falsely) in the top panel's menu. Should I make separate bugs for those?

Ignore #44 - thought I had installed the fix, but that was not the case.

The attached screenshoot comes up when network manager needs a password but is unable to bring up the prompt. Notice that the Connect button is greyed out.

Alan, make sure you upgrade properly. Right now you have packages installed with different versions. The fixes to NetworkManager to *avoid crashing* with ipw2200 have landed in Precise already; so running a full upgrade will likely fix this.

This doesn't mean that everything is fixed however; WPA-secured networks will still be unavailable for connection, because there is no way to tell whether the device supports it if the driver reports it doesn't. This needs to be fixed at the kernel level.

#47:
For me, Wicd manages to connect to WPA secured networks, so either it "guesses" that the device supports it or it gets the info in another way.

since this device does support wpa, isn't a quick workaround to override what is returned until it is fixed in the kernel ? otherwise. Considering precise release date, this needs to be fixed else networkmanager is useless for anyone with one of these cards.

I have unfortunately little faith after a major issue I reported before natty release, which the fix was relatively simple, was never done, and is still broken and will remain so until natty is out of support, and then closed, yet be broken for all users who ever tried natty :/

that's completely unrelated of course, but a point of annoyance for me as I have to modify a ubuntu distribution I provide for a specific device to work around the issue, but it has left me with "bad vibes" about bugs in ubuntu - #762806 if you are interested.

I realise that fixing it in nm is the wrong way of course. sorry for my previous message if it sounded unappreciative. Thanks for the work with this issue so far.

It should be fixed this week in NM, pending a freeze exception : the fix is
already upstream.

excellent news - do you have any reference/commit id for the fix ? saves me git bisecting to try and locate at what point it broke, which I was considering doing this week.

aah, a fix in nm rather than a kernel fix. I'll give it a try thanks.

I built network-manager/network-manager-gnome packages with those patches in, and I am still unable to connect to my wpa network (my wireless network is disabled in the menu).

All that these patches do is to avoid crashing because of the ipw2200 driver not listing capabilities. Since the capabilities are listed as not supporting WPA (or anything, for that matter), the networks are disabled in the menu.

You may be able to connect anyway by using the "connect to hidden" functionality until this is fixed in the kernel.

Sorry a misunderstanding then. When I posted in #49 I was referring earlier to the kernel not returning correct information about the hardware - then you referenced some patches and I assumed you meant they were a workaround (hence the comment about not having to git bisect). Ill debug it in the kernel then. The patches did seem somewhat unrelated (wpa ad-hoc stuff).

It's a related issue. The fact that this is missing from the kernel module triggers a crash in nm-applet. We've fixed this since it's obviously better to avoid crashing for no reason :)

Small update, after installing the lastest upgrades per 2012-04-03 - straight after a clean install, this problem hit my netbook test install. I was able to fix it by installing the network-manager-gnome package.

Ubuntu 12.04 LTS (Precise Pangolin) Beta 2 - Desktop - AMD64
Samsung n210
Intel Atom N450 1.66 GHz
1GB DDR2

note for those with the problem of not being able to connect to a wpa network on ipw2200 - I have put some packages on my a ppa - https://launchpad.net/~jools/+archive/ipw2200 that use wext instead of the nl80211 interface working around the problem. Would be nice if network manager could have a quick fix for this (checking for the ipw2200 hardware and then using wext instead). as it's clear no fix will make it into the kernel for precise

also see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/973241

Thank you soo much Jools! Now I don't have to use Wicd anymore, it's working great!

Thanks Jools. Works now.

Just posting to say thanks very much for the ppa! My wireless can now recognise WPA again.
