BCM43142 quick howto

Emerge driver if not emerged:

emerge net-wireless/broadcom-sta

Find and remove broadcom modules if any:

lsmod  | grep "brcmsmac\|b43\|ssb\|bcma\|wl"
rmmod b43
rmmod wl
rmmod brcmsmac
rmmod ssb
rmmod bcma

Load new driver:

modprobe cfg80211 wl

Should work!

Blacklist all unnecessary broadcom modules to prevent it’s loading:

echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf
echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf
echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf
echo "blacklist brcmsmac" >> /etc/modprobe.d/blacklist.conf
