网络管理器里可以识别网卡，但无法上网，google后发现很多方法，但都不顶用，最后发现http://linuxwireless.org/en/users/Drivers/b43这篇文章能解决问题，具体方法如下：
Fedora
With Fedora 10 and above, You need to install the b43-fwcutter tool (which will extract firmware from the Windows driver) and wget:
su - 2 yum install b43-fwcutter wget
Next, download the Windows driver:
1 wget http://downloads.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
Next decompress, extract and copy firmware to /lib/firmware directory.
tar xjf broadcom-wl-4.150.10.5.tar.bz2 2 cd broadcom-wl-4.150.10.5/driver 3 b43-fwcutter -w /lib/firmware/ wl_apsta_mimo.o现在就可以连接无线网络了
