[Henrik Steensland]

After the following upgrades, wireless stopped working.
Look at ieee80211 and ipw2200 in the logs below:

Running Hardy 2.6.24-21-generic
Rebooting with older kernel 2.6.24-20-generic works -- it doesn't cause the errors above.

Confirming as well.

I just did a fresh install of Hardy from an a CD release with a 2.6.24-16 kernel.
Wireless (ipw2200) works flawlessly but an upgrade to 2.6.24-21 did break my setup.

Confirming the same bug here running Hardy with 2.6.24-21-generic kernel.
After upgrade of linux-ubuntu-modules-2.6.24-21-generic to (2.6.24-21.31) version wireless stopped working with the same error described. Rebooting the system with kernel 2.6.24-20-generic makes the wireless to function again.
I think I'll change the status to Confirmed.

[cpauquez (cpauquez)]

Same bug here.
Hardy Heron with 2.6.24-21 kernel.

Roll-back to previous version solved problem for me:
dpkg -i /var/cache/apt/archives/linux-ubuntu-modules-2.6.24-21-generic_2.6.24-21.30_i386.deb

[Mircea (tramir)]

Same here. Made wireless unusable and had to roll back to 2.6.24-20-generic. Problem is, it took me a while to find out that it was due to the modules upgrade...

[Sébastien Valette (sebastien-valette)]

+1 here... back to 2.6.24-20 also...

[Vicente Balaguer (vbalaguer)]

Same bug here.
Hardy Heron with 2.6.24-21 kernel.

[JoeInnes (joeinnes+launchpad)]

Just adding my voice to the others - yes, I have the same issue.

Rolling back fixes, as does using the previous kernel.

[Hugo Nascimento (hadn)]

I also confirm this bug for a Sony laptop, VAIO VNG-FS415M. Its wireless card stopped working after upgrading the system with the following packages:
 * linux-ubuntu-modules-2.6.24-21-generic (2.6.24-21.31)
 * pciutils_1%3a2.2.4-1.1ubuntu6_i386.deb

Module ipw2200 does not load any longer:

When booting the system with the previous kernel version, the wireless works.

fwiw, unloading ieee80211_rtl, then loading ieee80211 and then ipw2200 will still spit out some errors, but will leave you with working wireless until this bug is fixed.

[Henrik Steensland (henrik-steensland)]

Why is this marked as a duplicate of 258344 ("Hardy does not have support for Realtek 8187 USB ")
This has nothing to do with USB and has been working perfectly until the recent upgrade. Please explain or remove the duplicate status.

[Cinus Marco (cinus-marco)]

adding another wireless network card that doesn't work with this kernel

Intel Corporation PRO/Wireless 2915ABG

downgrading to the previous one solves the issue.

[Philip Peitsch (philip-peitsch)]

If you are still suffering this issue on Ubuntu Hardy with the backports repo enabled, try installing both linux-ubuntu-modules-2.6.24-21-generic and linux-ubuntu-modules-2.6.24-21-386 restores something to its proper location.

I fixed this on hardy by doing the following:
sudo apt-get install linux-ubuntu-modules-2.6.24-21-generic linux-ubuntu-modules-2.6.24-21-386
