我有一个 alfa awus036h，但我不知道如何在 ubuntu 14.04 上安装驱动程序。当设备插入且无线开关关闭时。这是 的输出lsusb。

答案1
我有一个使用相同驱动程序的设备，只是标记为 ralink USB Wifi Dongle。这是我为使它正常工作所做的事情：
更新：如果您还没有内核头文件，您可能需要下载它们：
sudo apt-get install linux-headers-$(uname -r)
插入加密狗，然后在终端中运行以下行：
git clone https://github.com/porjo/mt7601.git
cd mt7601/src
make
sudo make install
sudo mkdir -p /etc/Wireless/RT2870STA/
sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/
sudo modprobe mt7601Usta
之后，它会在 GUI 网络工具中恢复。可能需要重新启动。
希望有所帮助。
答案2
有一个 ppa repo 用于此 -MT7601 STA 驱动程序我已经测试过了RT2870驱动程序，它对我有用。
插入 USB 适配器并运行以下命令：
sudo add-apt-repository ppa:thopiekar/mt7601
sudo apt-get update
sudo apt-get install mt7601-sta-dkms
安装完成后，单击 Wi-Fi 网络图标，您应该会看到 USB 适配器网络接口。
答案3
在继续使用@Hitsugaya198 解决方案之前，你必须diable 内置 wifi 适配器如下。
将以下行添加到 /etc/network/interfaces：
iface wlan0 inet manual
NetworManager 不管理在接口文件中配置的接口。如果 wlan0 不是内置接口的名称，请将其替换为您要禁用的接口。
然后重新启动网络管理器
sudo service network-manager restart
完成上述步骤后，继续使用@Hitsugaya198 解决方案，效果非常好。
答案4
如果您使用的是 debian 8 或 debian 9，以及 ubuntu 16，则驱动器已安装。问题是驱动器无法处理接口指定的名称。要使驱动器正常工作，只需重命名卡。在文件中/etc/ default/grub更改行，使其看起来像这样：
GRUB_CMDLINE_LINUX = "net.ifnames = 0 biosdevname = 0"
然后运行以下命令：
sudo grub-mkconfig -o /boot/grub/grub.cfg
只需重启机器即可。这样驱动器就可以正常工作了。
