在 ubuntu 13.04 lenovo g580 笔记本电脑中未检测到无线网卡

之前 wifi 在 ubuntu 13.04 lenovo g580 笔记本电脑上无法使用，然后我安装了一些软件包，重新启动了系统。然后所有设置/网络中都没有 wifi 设置。之前它显示断开连接，但现在甚至连这个都没有显示。这是我的网络属性

请建立临时的有线以太网连接并打开终端并执行以下操作：

sudo apt-get install linux-firmware
sudo modprobe brcmsmac

断开以太网。你的无线现在能用吗？如果没有，请查看日志以寻找线索：

dmesg | grep -e wl -e brcm
