双启动Ubuntu 14.04非常慢的Wifi
提问于 2015-07-24 12:30:45
我有惠普展览馆-g6笔记本电脑，我安装了Ubuntu14.04.2LTS与Windows 7双引导。WiFi连接非常慢。我在speedtest.net上做了测试，得到了0.20MB，但预期值是5-7MB。此外，WiFi在Windows 7上运行得很好
以下是关于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Settings > Software &Update>其他驱动程序，并检查是否有您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。
要查找您的无线网卡的名称，请打开一个终端并运行：
sudo lshw -C
