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] :-)
