无法连接到Ubuntu 14.04中的任何Wifi
我有Ubuntu 14.04。 我已经尝试连接到我公寓的AT＆T路由器，但我看不到符号。 我已尝试从附加驱动程序安装WiFi路由器的驱动程序，但列表中没有驱动程序。
lspci命令的输出是：

如果您已安装USB，请将其插入并向下钻取到pool> restricted> b> bcmwl并将bcmwl-kernel-source拖到桌面上。 对pool> main> d> dkms执行相同操作并将dkms拖到桌面上。 然后安装：
cd ~/Desktop sudo dpkg -i dkms*.deb sudo dpkg -i bcmwl*.deb sudo modprobe wl
您的无线现在应该正常工作。
您需要为Broadcom芯片安装驱动程序。 为此，请打开终端。
使用有效的Internet连接运行这两个命令（使用以太网）：
wget https://launchpad.net/ubuntu/+source/bcmwl/6.30.223.141+bdcom-0ubuntu2/+build/5254885/+files/bcmwl-kernel-source_6.30.223.141%2Bbdcom-0ubuntu2_amd64.deb -O driver.deb sudo dpkg -i driver.deb
重启并享受您的WiFi！
如果您无法连接到互联网，您当然可以在Windows上下载文件 ， 将其保存到USB记忆棒 ，重新启动到Ubuntu，安装USB记忆棒，然后双击.deb文件。
我目前遇到同样的问题。
我使用的是Android 4.4.2，我通过USB Tethering访问了Internet。 该选项隐藏在我的设置中，因此我使用了免费的“USB Tethering Pro”应用程序。
