网上给你搜到一个方法
http://linuxg.net/how-to-fix-broadcom-b ... inux-mint/

Remove the default driver: (删除默认的驱动)
$ sudo apt-get remove --purge bcmwl-kernel-source

Install a the Linux Firmware nonfree drivers: (安装linux firmware)
$ sudo apt-get install linux-firmware-nonfree

Load the b43 module: (加载b43模块)
$ sudo modprobe b43

To make it work automatically, do (thank you Ja7i3r for this hint) : (开机加载模块)
$ sudo su
# echo "b43" >> /etc/modules

最后一步我不确定13.10是不是可以这么做, 上面那步没问题的话找个开机加载模块的方法就OK了

问个问题，我家电脑装的是双系统，为什么电脑上win7可以连上wifi而ubuntu却搜不到？
