Broadcom STA Wifi used to work on 11.10

[Kronalias]

Just installed 12.04 and no wifi.

Settings => Settings Manager => Additional Drivers =>

This driver may well be activated, but it certainly isn't in use!

Clicking on the up/down arrow thingy on the top panel reveals:

Nothing there about wifi...

... Is it me? (btw, it worked 100% under Xubuntu 11.10)

Oh, boy! The fun begins! Please open a terminal and show us:

lspci -nn | grep 0280
lsmod | grep -e b43 -e wl

The pipe symbol | is on the right side of my US keyboard on the same key with \. Thanks.

Hi Chili, thank you but no, no to your 'The fun begins'. That started yonks ago!

Usually if it's not broken then you haven't tweaked enough ... but in this instance it's a brand new install..
I've been using the daily builds for some time and everything was going swimmingly until today's release (escape?) when it all went pear shaped.

Here's the output you asked for:

martyn@laptop:~$ lspci -nn | grep 0280
05:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)
martyn@laptop:~$ 
martyn@laptop:~$ lsmod | grep -e b43 -e wl
wl                   2646601  0 
lib80211               14040  1 wl
martyn@laptop:~$

Does this give you the info you were after?

Thanks in advance for any help or advice!

Having the same issue on stock Ubuntu 12.04 64-bit, freshly installed.

Here's the results of the commands:

$ lspci -nn | grep 0280
30:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11a/b/g [14e4:4312] (rev 01)
$ lsmod | grep -e b43 -e wl
wl                  2568210  0
lib80211              14381  1 wl

sudo modprobe b43

Did the trick for me. Any reason why this isn't starting up on its own?

[chili555]

The fun begins because rumor has it that Additional Drivers misidentifies the correct driver for some Broadcom cards and installs the incorrect one. I believe you are my first case!

Please do:

sudo apt-get install linux-firmware-nonfree
sudo modprobe -r wl
sudo modprobe b43

If it works as expected, we'll need additional steps to make it permanent.

Please try what I suggested above and let me know.

Yup, works for me. I tried it the first time with the firmware-b43-installer package, and it also works.

Excellent! Please do:

sudo apt-get remove --purge bcmwl-kernel-source

Look around in /etc/modprobe.d and make sure the purge did not leave any blacklist of b43; if so, remove it:

sudo rm /etc/modprobe.d/whatyoufound

Reboot and enjoy.

@Kronalias--

Verify before you try this fix, please.

Same problem when upgrading from 11.10. After reboot I had to use LAN and then update manager showed error. Then "apt-get install -f" as it said and it removed almost everything including kernel files. Well, home folder was still on it's place and did backup personal files to usb-stick. Then fresh install. Install ready and rebooting to OS - no wlan and restricted driver didin't work. Then googled and found this, and it is for BCM4311

sudo apt-get install b43-fwcutter firmware-b43-installer

And it worked. You may optionally try this first, it removes all broadcom stuff from your system: sudo ap((read_before_copy_paste)t-get purge broadcom-sta-common broadcom-sta-source bcmwl-kernel-source

Now system functions perfectly! Maybe they should update install disk what comes to broadcom chips.
