Wireless modules blacklisted after update (12.04)

[SThom27]

I was prompted to update today, but something went wrong. It didn't fully update and when I restarted, all I got was a black screen. So I rebooted into "safe mode" and finished the update, but when I restarted my wireless wasn't working.

I checked http://help.ubuntu.com/community/BroadcomSTA(Wireless) and made sure I had the right drivers installed. After making sure the bcmwl-kernel-source package was installed, I went to the Additional Drivers page and tried to install the STA drivers. It didn't work. It told me to check /var/logs/jockeylog for what was wrong. Here's what I saw:

2012-10-10 21:24:23,312 WARNING: /sys/module/wl/drivers does not exist, cannot rebind wl driver
2012-10-10 21:24:23,350 DEBUG: BroadcomWLHandler enabled(): kmod disabled, bcm43xx: blacklisted, b43: blacklisted, b43legacy: blacklisted

So, no wireless still.

Here's the rest:

Dell 1545 with a the BCM4312 wireless card. "lsmod" shows no wireless modules and "iwconfi" shows no wireless extensions. I'm running Ubuntu 64-bit with the 3.5.0-17-generic kernel. Also this:

$ sudo /etc/init.d/networking restart
 * Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces
 * Reconfiguring network interfaces... 

I have no idea what updates were trying to install when all this broke. I've also replaced network-manager with WICD. Any help is appreciated.

Having the same issue with Lubuntu after update. Any help is appreciated.

Will you both please post:

lspci -nn | grep 0280

Thanks.

I tried everything I could find on this forum and on AskUbuntu and finally decided it might be due to installing Gnome Shell, Cinnamon, or the full Kubuntu suite. After fully uninstalling every little app, widget, and library, still nothing worked.

So, I backed everything up and reinstalled. Hope you get some help. I don't know if this forum is just that dead or what, but I don't have time to wait days without wireless.

FYI, there's a lot of threads in this forum and on AskUbuntu with lots of things to try. In my case, I think it was related to having installed the full Kubuntu desktop complete with all libraries and apps. I had uninstalled network-manager and replaced it with WICD and that could have been part of the problem as well.

Good luck!

Edit: I don't know if it'll help now, but here's what was asked for (from my now working re-install)

0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

It's amazing the urban lore that gets spread around and accepted as gospel. It's not your fault. The ONLY reason is that you don't have the correct driver/firmware combo for your device. All the Gnome/Unity/NM/Wicd is red herring and guesswork on the part of the post answering 'experts.'

Please do:

sudo su
apt-get remove --purge bcmwl-kernel-source
apt-get install firmware-b43-lpphy-installer
echo b43 >> /etc/modules
exit

Reboot and let us have your report.

I followed the instructions above, but still do not have wireless.
