Ubuntu 体验（Linux Kernel 2.6.38-9）无线网卡驱动问题

升级UBUNTU11.04后一直搜索不到无线网络，用自带的驱动无法工作，也试过好多方法，自己编译wl，还是失败。

最后解决方法

Add a "contrib" component to/etc/apt/sources.list, for example:

# Debian Squeeze/6.0
deb http://ftp.us.debian.org/debian squeeze main contrib non-free

Update the list of available packages and install thewireless-toolspackage:

sudo apt-get update
sudo apt-get install wireless-tools

Install the appropriate firmware installer package:

For 802.11b/g devices with a BCM4306 revision 3, BCM4311 or BCM4318 chipset, installfirmware-b43-installer:

sudo apt-get install firmware-b43-installer

For 802.11b/g devices with a BCM4312 LP-PHY chipset (PCI-ID 14E4:4315), installfirmware-b43-lpphy-installer:

sudo apt-get install firmware-b43-lpphy-installer

The necessary kernel module should beautomatically loaded.

当然你自己可以加载

sudo modprobe b43

OK,无线网络的指示灯亮了，驱动安装成功！

注：如果开机无线模块不自动加载，可以在配置文件/etc/modules中加入

b43
