Installing Broadcom wl driver v 5.10.27.11 for linux kernel 2.6.27-r7

Since apparently linux kernel no longer supports bcm43xx, and for some reason 2.6.27-gentoo-r7 doesn't include b43 or b43legacy, I was pleasantly surprised when I learned Broadcom released native linux drivers [finally]: http://www.broadcom.com/support/802.11/linux_sta.php

I couldn't find any directions for v 5.10.27.11 - everything was for v 5.10.27.6 (and the patch file for that hosted by jaux.net didn't work for the new version released in Dec 2008)

credit for these directions goes to:

http://djkaos.wordpress.com/2008/10/25/installing-broadcom-80211-linux-sta-driver/


1] Download driver from http://www.broadcom.com/support/802.11/linux_sta.php

my file was "hybrid-portsrc-x86_32_5_10_27_11.tar.gz"


2] Create and enter workspace:

~ # mkdir /usr/src/wlan
~ # cd /usr/src/wlan/
wlan # mkdir build


3] Extract Broadcom download

wlan # tar -zxvf /path/to/hybrid-portsrc-x86_32_5_10_27_11.tar.gz


4] Get patch hybrid_wl-5.10.27.11_patch-2.6.27-ARCH

NOTE: this is NOT hybrid_wl-5.10.27.6_patch-2.6.27-ARCH

You can find this patch at the very bottom of this page.

wlan # cp /path/to/hybrid_wl-5.10.27.11_patch-2.6.27-ARCH /usr/src/wlan/


5] Install the patch:

wlan # patch -p1 < hybrid_wl-5.10.27.11_patch-2.6.27-ARCH output: patching file src/wl/sys/wl_iw.c


6] Compile the patched Broadcom source

wlan # make -C /lib/modules/2.6.27-gentoo-r7/build M=`pwd` clean
wlan # make -C /lib/modules/2.6.27-gentoo-r7/build M=`pwd`

output: make: Entering directory `/usr/src/linux-2.6.27-gentoo-r7' CC [M] /usr/src/wlan/src/wl/sys/wl_iw.o CC [M] /usr/src/wlan/src/shared/linux_osl.o LD [M] /usr/src/wlan/wl.o Building modules, stage 2. MODPOST 1 modules WARNING: modpost: missing MODULE_LICENSE() in /usr/src/wlan/wl.o see include/linux/module.h for more information CC /usr/src/wlan/wl.mod.o LD [M] /usr/src/wlan/wl.ko make: Leaving directory `/usr/src/linux-2.6.27-gentoo-r7'


7] Check to make sure the module works:

wlan # insmod wl.ko]


8] Ensure b43/b43legacy/bcm43xx are not in use by adding them to the blacklist in /etc/modprobe.d/blacklist:

wlan # echo "blacklist b43" >> /etc/modprobe.d/blacklist
wlan # echo "blacklist b43legacy" >> /etc/modprobe.d/blacklist
wlan # echo "blacklist bcm43xx" >> /etc/modprobe.d/blacklist


9] Check to make sure it actually is working:

There should be a new wireless interface...eth1 or wlan0:

wlan # iwconfig
wlan # iwlist scanning


10] Install the new driver:

wlan # mkdir -p /lib/modules/2.6.27-gentoo-r7/build/drivers/net/wireless/

wlan # cp wl.ko /lib/modules/2.6.27-gentoo-r7/build/drivers/net/wireless/

wlan# depmod -a

wlan # rmmod wl

wlan # modprobe wl
