Ubuntu 14.04 无法连接任何 Wifi

我有 Ubuntu 14.04。我尝试连接到公寓中的 AT&T 路由器，但我看不到该符号。我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。

该命令的输出lspci是：

答案1

如果您有安装 USB，请将其插入并向下钻取到池 > 受限 > b > bcmwl，然后将 bcmwl-kernel-source 拖到您的桌面。对池 > 主 > d > dkms 执行相同操作，然后将 dkms 拖到您的桌面。然后安装：

cd ~/Desktop
sudo dpkg -i dkms*.deb
sudo dpkg -i bcmwl*.deb
sudo modprobe wl

你的无线网络现在应该可以正常工作了。

答案2

您需要安装 Broadcom 芯片的驱动程序。为此，请打开终端。

使用有效的互联网连接（使用以太网）运行这两个命令：

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

重新启动并享受您的 WiFi！

如果你无法连接到互联网，你当然可以点击此处下载文件在 Windows 上，将其保存到 USB 记忆棒，重新启动进入 Ubuntu，挂载 USB 驱动器，然后双击该.deb文件。

答案3

我目前遇到了同样的问题。

我使用的是 Android 4.4.2，我通过 USB Tethering 访问互联网。该选项在我的设置中被隐藏，所以我使用免费的“USB Tethering Pro”应用程序来完成这项工作。
