我有一台 HP pavillion-g6 笔记本电脑，安装了 Ubuntu 14.04.2 LTS 和 Windows 7 双启动。WiFi 连接非常慢。我在 speedtest.net 上进行了测试，得到 0.20 MB，但预期是 5-7 MB。此外，WiFi 在 Windows 7 上运行良好
以下是有关我的笔记本电脑的一些信息：

我不是专家，但你可能需要为你的无线网卡安装第三方驱动程序。最简单的方法是转到“设置”>“软件和更新”>“附加驱动程序”，然后检查是否列出了你可以启用的无线驱动程序。
否则，您可能需要手动下载驱动程序，在这种情况下，驱动程序附带的文档可能会列出故障排除信息。
要查找无线网卡的名称，请打开终端并运行：
