The firmware works great on my new mac mini ( mid 2011 - no optical drive ). Thanks a ton Marco !!!

Just published *.deb packages in my ppa for mactel. You can fix issue from a terminal doing:

sudo apt-add-repository ppa:mpodroid/mactel
sudo apt-get update
sudo apt-get install linux-backports-modules-cw-3.2-3.0.0-14-generic firmware-b43-installer
sudo modprobe b43

Marco: Your PPA is the best support for MacbookPro8,2 until they fix this bug.

I don't see a package by that name on your PPA right now. Could you update / fix it for me?

Thanks Buck

Di you checked https://launchpad.net/~mpodroid/+archive/mactel/+packages expanding b43-fwcutter?

Let me know if this solve your issue

Dear Marco, after many trials I am not able to apply your solution. I have a macbook pro 15'' of December 2011 (8.2? 8.3?). I feel absolutely frustrated with the broadcom 4331. After several re-installations of ubuntu 12.04 alpha, beta, I just got working (miraculously) the wireless after some patching + update, but it messed up afterwards and I had to reinstall from scratch. No more luck afterwards.

I see linux-backports-modules-cw-3.2-3.0.0-14-generic in one of your subdirectories but I dont know how to load it ( when I try "sudo apt-get install linux-backports-modules-cw-3.2-3.0.0-14-generic" it isn't found)

 I would extramely appreciate any help.

Hi Jose Manuel

Your laptop should be 8.2 (x.3 are 17" models).

I packaged wireless module for Ubuntu 11.10 only. So, try that stable
version

Remember to carry on installation in bios mode, not EFI

Hi there,

It looks like the patch downloads the firmware from "www.lwfinger.com/b43-firmware", I'm a bit curious where the firmware comes from and is it trustworthy? (I know that linuxwireless.org does have this link, but still ...)

D.

That link is mentioned in official linuxwireless page: http://linuxwireless.org/en/users/Drivers/b43#Other_distributions_not_mentioned_above

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm that the patch is working fine on my MacBook Pro 8,1 (early 2012) running Ubuntu 12.04. Thanks, Marco.

Thanks Marco Pozzato. The version in your repo got wireless up and running on my Mid-2011 Mac Mini on Linux Mint 13 (ubuntu precise branch). The version in the official repo still doesn't have this patch as of today as I tried it earlier and it was a no go.

Just an FYI though. If you already have kernel 3.2 then linux-backports-modules-cw-3.2-3.0.0-14-generic isn't needed.

shinji@shinji-Macmini ~ $ uname -a

Does this add support to n mode? I have been having problem when trying to connect to certain access point at work. While the wireless card support b/g/n/ when I do iwconfig the out put is always
wlan0 IEEE 802.11b/g ...
I am running ubuntu 12.10.

I can confirm I cannot run wireless N with the patch. Without the patch, wireless doesn't work at all. I'm running ubuntu 12.10 on a macmini 2012.

Also created a thread with some details: http://ubuntuforums.org/showthread.php?t=2095426

Hi, all.

Debian already have an "should work" version in experimental.

I believe that anyone know better than me can do something.

Marco Pozzato, as per https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx your chipset is supported. Could you please advise if this is still an issue for you in a supported release?
