How to get the Broadcom wireless drivers working in Chromium OS

Update 16/12/13. Please Note: You need to use the special edition builds noted to use Broadcom drivers


A shameless cobbling of the build files from leads to a fix for the Broadcom wireless issues!

As ever, boot your device and get to su command line  ([ Ctrl ] [ Alt ] [ F2 ]), log in as chronos and then:

sudo su
mount -o remount, rw /
sudo echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf
sudo echo "blacklist b43legacy" >> /etc/modprobe.d/blacklist.conf
sudo echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf
sudo echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf
sudo echo "wl" >> /etc/modules
sudo touch /etc/modprobe.d/wl.conf
sudo echo "alias wlan0 wl" >> /etc/modprobe.d/wl.conf
cd /lib/modules/3.4.0/kernel/drivers/net/wireless/
sudo insmod /lib/modules/3.4.0/kernel/net/wireless/cfg80211.ko
sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211.ko
sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211_crypt_ccmp.ko
sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211_crypt_tkip.ko
sudo insmod /lib/modules/3.4.0/kernel/net/wireless/lib80211_crypt_wep.ko
sudo insmod /lib/modules/3.4.0/kernel/drivers/net/wireless/wl.ko
sudo depmod -a

Wireless networks should start to miraculously appear and you can connect as required.

One minor gripe is that the driver doesn’t seem to like hidden SSID and bombs out when attaching to them. Other that that it seems to work fine!

Huge thanks to Doug Anson @ Dell for providing the driver.

As per the readme located a good few variants should be supported. As ever, its tested on a Dell Inspiron 910 only (Mini 9)!
