1. 下载64位的BCM4312无线网卡驱动

# mkdir /root/wl/
# cd /root/wl
# wget ftp://ftp.debian.hu/pub/linux/distributions/frugalware/frugalware-testing/source/network-extra/bcmwl/hybrid-portsrc_x86_64-v5_100_82_112.tar.gz
# tar zxf hybrid-portsrc_x86_64-v5_100_82_112.tar.gz

2. 安装驱动

# ln -s /usr/src/kernels/2.6.32-358.23.2.el6.x86_64/ build
# make API=WEXT
# make install
# cp wl.ko /lib/modules/2.6.32-358.23.2.el6.x86_64/kernel/net/wireless/

3. 移除可能冲突的其它BROADCOM无线网卡驱动

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

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

4. 载入新驱动并添加开机启动

# modprobe lib80211
# imsmod wl.ko
# depmod -a
# echo "modeprobe wl" >> /etc/rc.local
