Fedora15中BCM4312无线网卡的安装

5月底终于出了Fedora 15的最终版，相信很多fedorafans都安装了。但问题就来了，我的小本“惠普CQ40-421TX”的在安装后无线网卡驱动不能识别我的无线网卡，经过一番折腾，这问题总算被我搞定了。

下面我写下安装方法。

先上官网：www.broadcom.com/support/802.11/linux_sta.php下载对应版本的驱动，因为我安装的系统是64位的，我下载了：64-bitdriver 5.100.82.38还要下载补丁：Patchfor compilation problem with kernel versions > 2.6.375.100.82.3。下载后我的到两个文件，分别是：hybrid-portsrc_x86_64-v5_100_82_38.tar.gz和5_100_82_38.patch。我把这两个文件保存在Fedora 15的主目录下。

下面开始安装：
先进入下载目录，即我的主目录
#cd /home/dauser

新建目录
#mkdir hybird_wl

# mvhybrid-portsrc_x86_64-v5_100_82_38.tar.gz hybird_wl/

# cdhybird_wl/

# tar xzfhybrid-portsrc_x86_64-v5_100_82_38.tar.gz

# mvhybrid-portsrc_x86_64-v5_100_82_38.tar.gz ../

然后打补丁
#cd /home/dauser

# mv 5_100_82_38.patch hybird_wl/

# cd/home/dauser/hybird_wl

# patch -p0 <5_100_82_38显示“patchingfile src/wl/sys/wl_linux.c”
# make clean显示“

#modprobe wl

重启，看看你的无线网络灯亮了没？呵呵。安装完成！原创，转载请标明。
