lucid: iwlagn stopped working after an update posterior to beta2

[Mirto Silvio Busico]

(Tried to submit erroneously as launchpad bug as #560554
Hope this is the correct procedure to submit a bug).

Kubuntu Lucid 64Bit updated at 12 Apr 2010
The wireless card doesn't work and the antenna led is off

With kernel 21 the problem remains

uname says:
Linux msb02 2.6.32-21-generic #31-Ubuntu SMP Tue Apr 13 20:37:36 UTC 2010 x86_64 GNU/Linux

[Mirto Silvio Busico (m-busico)]

Found a workaround procedure:

- update system (now uname says: Linux msb02 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:09:38 UTC 2010 x86_64 GNU/Linux)

- reboot

- uninstall completely everything network-manager related

- reboot

- install plasma-widget-networkmanagement (which installs other network-managere related packages)

- reboot

- give the commands:
rmmod iwlagn
rmmod iwlcore
rmmod mac80211
modprobe -v iwlagn

At this point the wifi antenna led switchs on

- reboot

Now the wifi is on again

Hi Mirto,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. 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. Please let us know your results.

Thanks in advance.

This appears to be resolved in mainline kernel 2.6.34-999 - although as it can be a transitory problem, more testing is required.

[Gareth Halfacree (o-launchpad-halfacree-co-uk)]

Cancel that - after half an hour, the wireless became unresponsive again on kernel 2.6.34-999 generic 64-bit.

A 3Com USB wireless dongle connected to the same system works fine.

Whoops - sorry for the false apport-collect. Disregard last attachment.

Sorry, I have only this 64 bit laptop (that I use for work) and cannot
test the upstream kernels.
All the other sacrificable machines I hace are 32 bit
