Having the same problem on a Dell inspiron. The culprit seems to be the latest restricted-modules update.
If you still have the 2.6.24-18 kernel in GRUB menu, you can boot that item until this problem is fixed.

Michele (mikelito) wrote :

I think we can confirm this one. The problem is clear, reproducible and the culprit is quite clearly the update of restricted modules.
see also,
which is exactly the same. one of the two should be marked as a duplicate

Confirmed on Hardy 8.04 32-bit - Wednesday's automatic updates of the following components broke the wireless on my HP Compaq 6720s laptop with Broadcom BCM 4310 chipset (wl driver):

I have confirmed this behaviour on 2 different laptops, and 3 Hardy 8.04 installs.

I too have this problem - it seems this file was removed from restricted modules:


This breaks wireless for BCM4310 chips.

a workaround until the fix is in, on Ubuntu that is.

use synoptic and force a version.
at least i had 2 in them.



This fix didn't work for me, as I was unable to force the version of one of the packages as the "Force" option in Synaptic was greyed out. My oldest previous kernel was - perhaps this fix works with but I have no way of trying.

i deleted 2.6.24-19 (just to make sure) and booted 2.6.24-18 (which did work previously) - sadly no dice.

I don't get the error when i do modprobe wl - or the Unknown symbols in demsg - but Wireless connection still does not work.

I will try to reinstall 2.6.24-18 and see if that helps

Tony Flury (anthony-flury) wrote :

Something very odd - i have gone back to the 2.6.24-18 module - and even re-installed it - and still no joy.

wireless connection is not functioning correctly - but it might be me.

Kinap (felix-flux) wrote :

kinda wierd, as my notebook had a choise of 2 version of the generic-modules.

but my main computer don't have them

well i think i was lucky then :)
 44 as being the one from hardy-updates the 42 from some place else, can't see anymore where it is from i think, as it only says (now).

think it was hardy-proposed.

i have selected every think on the updates tab in software sources

Through the Synaptic Package Manager, I enabled the "hardy-backports" repository and was able to remove the 2.6.24-19 modules to install the 2.6.24-18.41 modules and it worked for me (granted, I'm on a 64-bit rather than a 32-bit).

Either way, if you aren't seeing more than one version of the restricted modules, make sure you have the backports repository enabled.

Regression, overwhelming positive feedback, and a trivial one-liner patch in Makefile which only affects wl. Waiving the 7 day maturing period and copied to hardy-updates. Thanks to all for testing!

We will investigate how this could have happend to avoid it happening again.
