no wlan entry in nm-applet after dist-upgrade to karmic

[Prunus dulcis]

Network-manager applet does not show the wlan entry anymore after I just made a dist-upgrade from ubuntu jaunty to karmic. Only the wired network entry is visible but the wireless entry, which worked in jaunty ten minutes before is now not visible anymore (but the connection details are still in the connection editing panel.

Not sure, where the problem comes from. But it seems, my inbuilt wireles card is not recognized anymore.

1) Ubuntu karmic (develoopment branch) Release 9.10
2) network-manager 0.7.1-0ubuntu1
3) be able to choose the wireles network to connect to
4) the wireles network option does not show in network-manager applet

Now installed jaunty again (but karmic still available by dual-boot) and in jaunty, wlan still works. Just to confirm it is not a hardware issue.

I've been following karmic development for a while, and only in the last week did this bug appear.

I'm using an Intel 3945ABG adapter, while the OP had an Atheros AR5212

I believe this and bug 410492 describe the same problem. Since that one has already been accepted, I'll mark this a duplicate of that.

After having read the other bug-report I am still unsure, if this is the same bug but I do not know anything about kill-switches.

But as far as I understand, in the other bug-report internet works, if the hardware kill-switch was deactivated at boot. If it was activated, the status could not be changed while running.

In my case I do not set any kill-switches and without changing any setting, switch whatsoever myself, the wlan-entry is shown in ubuntu jaunty and not in ubuntu karmic. So as far as I understood it, this seems not to be a duplicate but. I would heartily welcome any clarification or enlightenment on that issue, since for now this renders ubuntu karmic nearly unusable for me [unless I plug in an external wlan adapter, which works] :-)

I don't think this case is a duplicate of bug 410492. In my case my switch toggle appears to no longer function (if not off at boot) where with prior kernels/nm/etc it did). Also in my case, plugging in an external adapter (post boot) will not work. (Another unrelated bug is if I have my usb keyboard and mouse plugged in pre-boot, they will not work, but hotplug works correctly) - I think when the notes say major breakage, they weren't kidding. :)

Removed the duplicate status for now since this also according to the other bug reporter does not seem to be a duplicate.

Is it possible, that the driver was removed from kernels 2.6.31.x onwards? I just tried the 2.6.31-6-generic kernel to get rid of some intel-graphics-driver bugs in Jaunty, and as soon as I use the new kernel, the problems of my bug-report appear in Jaunty as well.

So I would suggest this is rather a problem with the kernel than with network-manager? [I really am not knowledgeable when it comes to linux system internals :-( ]

I installed a daily ubuntu-karmic build from yesterday (02. September) and it works now beautifully (even stronger signal reception than before :-)). Thanks to whoever made it work again!
