[SOLVED] Wifi working on Macbook Pro 8,2 on Ubuntu 12.04

[raritan01]

I can't take all the credit, but this is what I did to get my bcm4331 to be recognized in Ubuntu 12.04.

Got these instructions from Tim Hentenaar's Blog and tweaked them a bit
http://hentenaar.com/serendipity/ind...s/2012/05.html

Run the following in the terminal:
$ sudo apt-get install b43-fwcutter firmware-b43-installer
$ sudo dpkg-reconfigure firmware-b43-installer
response from terminal:
$ No chroot environment found. Starting normal installation
$ Unsupported device(s) found: PCI id 14e4:4331
Aborting.

then run:
$ sudo modprobe b43
$ export FIRMWARE_INSTALL_DIR="/lib/firmware"
$ cd ~\Downloads
$ wget http://www.lwfinger.com/b43-firmware...00.138.tar.bz2 $ tar -xjf broadcom-wl-5.100.138.tar.bz2
$ sudo b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" broadcom-wl-5.100.138/linux/wl_apsta.o

You'll get a response like this:
This file is recognised as:
filename : wl_apsta.o
version : 666.2
MD5 : e1b05e268bcdbfef3560c28fc161f30e

...and a lot of extracting will happen

Then enter:
$ dmesg | tail -2

You'll get a response like this:
[ 5866.172626] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 5870.282827] applesmc: FS! : read arg fail

Then just enable/disable wireless in Network Manager and it works!

Hi, please try:

echo "blacklist wl" | sudo tee -a /etc/modprobe.d/blacklist.conf

Then:

sudo su 
echo b43 >> /etc/modules 
exit

Reboot
Thanks

This also worked on my Mid-2012 Macbook Pro 9.1 (which was giving me the exact same error message). Thanks very much!

Thanks a lot for this, I have spent the past 5 hours reading forums. This was the only one I have come across that actually worked on my MBP 9,1.

Thanks, going to try this when i get home from work. Hopefully its solves my problems. Only just installed on my 8,1 macbook pro using refit.

EDIT: This worked perfectly for me thanks a bunch!
