BCM4331 Wireless

I've searched and and it looks like the best way to get this running is through NDIS. However I'm having a heck of a time actually trying to locate Windows XP drivers for this. Anyone have any information?

Thanks
 
Reading this alongside Get Broadcom BCM4331 wireless network card running in 9.1 (reportedly a duplicate of Is it possible to use the Broadcom BCM4313?) and How do I install the src component post install?

When asked to suggest updates to https://wiki.freebsd.org/AppleMacbook I took the nearest available Apple notebook, an early 2011 MacBookPro8,2 with BCM4331. I overwrote an installation of 12.0-CURRENT with 11.0-RC2 and here, for the record, are my notes. Some use of sudo(8) because I'm from a TrueOS Desktop background.

https://www.freebsd.org/cgi/man.cgi?query=bwn&sektion=4

Code:
$ sudo portsnap auto && sudo pkg install b43-fwcutter dialog4ports gmake subversion && \
sudo svn checkout https://svn.freebsd.org/base/releng/11.0 /usr/src && \
cd /usr/ports/net/bwn-firmware-kmod && sudo make install clean

Code:
$ cat /boot/defaults/loader.conf | grep bwn
if_bwn_load="YES"               # Broadcom BCM43xx IEEE 802.11 wireless NICs
$

Code:
$ kldstat

16    1 0xffffffff82b6e000 393a     ng_socket.ko
$

Code:
$ sudo ifconfig wlan create wlandev bwn0 ssid piano up
Password:
ifconfig: SIOCIFCREATE2: Device not configured
$

I might retry with 12.0-CURRENT but no rush.

Postscript

From Any success stories for BCM 4331? (2015-04-27):

… currently not supported - full stop (at least on 64bit installs, apparently it is possible to make 32-bit ones work with ndis(4) ). I am currently working on upgrading bwn(4) to support these newer cards however I am still a way off. I’ll let you know what I find! …

Hi everyone,

I seem to have the same problem as a lot of other people who are trying to run FreeBSD on a Macbook/Macbook Pro. The Broadcom 4331 is not supported by bwn or bwi. I've read that it is possible to use ndis with a 32 bit driver but I would like to have native support...

I read an email on freebsd-wireless that someone was going to have a crack at adding functionality for the 4331;

Does anyone know how this is going? I am asking because I have picked up a copy of 'FreeBSD Device Drivers' by Joseph Kong from NoStarch.com. I was thinking of trying to write a driver, but if someone is already doing it I would be happy to help out in some way. I have a Macbook Pro 10,1 that is dual booting OS X and FreeBSD 10.3-RELEASE
 
NDIS with Windows drivers failed on 11.0-RELEASE. Guess I'll be back in a few years to see if any progress has been made on this.
