I'm not convinced it's actually what's breaking everyone's wifi;
specifically, this couldn't possibly be affecting iwlwifi; since it uses
nl80211 rather than wext -- the code changes are specific to wext. (And
also, because my wifi works just fine).
However, there is sufficient uncertainty with

broadcom-sta-dkms should already build with cfg80211/nl80211, there
shouldn't be a need to patch it to do so -- it's dependent on the kernel
version number, which should be higher than 2.6.32 on all the releases
we care about anyway
But the actual test in broadcom-sta is broken for the 3.0
It's breaking wifi also on broadcom :-)

My broadcom wifi stopped working with network manager (can't find AP,
while iwlist eth1 scan finds them) after the upgrade: downgrading the
package works

I can confirm that the patch fix_driver_wext_for_broadcom_wl.patch is
broken, supplicant stopped working with iwlwifi driver resulting with:
ioctl[SIOCGIWSCAN]: Argument list too long
ioctl[SIOCGIWSCAN]: Argument list too long
ioctl[SIOCGIWSCAN]: Argument list too long
ioctl[SIOCGIWSCAN]:
Mathieu: ¿Can you revert the patch? it's breaking everyone else's wifi,
I will think of a different approach to try to workaround the specific
issue on BCM4353 with wl driver (maybe it's better to submit a patch to
the wl driver itself).

Pau, It seems that your patch made my atheros card fail to find the AP.
I upgraded wpasupplicant from 1.0-2ubuntu1 to 1.0-2ubuntu2 today.
after reboot, my card cannot connect to the AP.
I run
sudo /sbin/wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd
to see what happend, and I got

Looking good so far; I'll just check back on the mailing list posts and
review/sponsor to Precise.

I can't reproduce that delay on 12.04 with a different system (but also
broadcom, using a 4312). I really wish this patch was accepted upstream
in some form or another before applying this to Precise, especially
since it really should be applicable to wpa 1.0 anyway.
Pau, could you please bring

This is a better patch, which fixes the driver_wext in wpasupplicant
when using broadcom's wl driver and shouldn't have effect when using any
other underlying wifi driver, this is adapted from here to the current
version of wpasupplicant in ubuntu:

I have not contacted upstream directly, as the development of
wpasupplicant 0.7.3 is stopped (wpasupplicant stable is now 1.0) and

The attachment fix_wl_timeout.patch of this bug report has been
identified as being a patch. The ubuntu-reviewers team has been
subscribed to the bug report so that they can review the patch. In the
event that this is in fact not a patch you can resolve this situation by
removing the tag 'patch'
Attached is a patch which reduces the waiting timeout from 30 seconds to
10 seconds, it is based on this:

Finally found the root reason of the problem! :-)
Both wl (broadcom proprietary driver) and brcmsmac (the open source
driver) are installed, in 11.10 this wasn't a problem since the
brcmsmac was not blacklisted, and even if the wl driver was loaded, it
failed silently and brcmsmac was used
I've been digging into this a bit more, it seems to me the problem is in
communication between network-manager and wpa_supplicant. I enabled
debugging in wpa-supplicant, see the attached log file.

I have the same issue here, MacBookAir4,2 with a Broadcom BCM43224
802.11a/b/g/n using 'wl' driver.
It takes around 30 seconds to connect to the wireless network after suspend in
12.04, while in 11.10 it was barely 5 or 6 seconds.

I've attached log of network-manager with debug enabled on both 11.10

broken and complains about missing nl80211.

The issue is not related to nl8021: modprobing 'mac80211' makes 'iw'
command work correctly, but the issue with network-manager taking too
long to re-connect still exists.
Any help fixing this would be appreciated.
