我在 Windows 上双启动运行 Ubuntu 16.04。虽然无线网络在 Windows 中运行良好，但 Ubuntu 右上角的网络菜单不显示任何可用的无线网络。
我访问互联网的唯一方式是使用以太网。

这network UNCLAIMED行字让我以为缺少驱动程序，所以我尝试使用ndisgtk我的无线适配器 RT3290 运行 Windows 驱动程序，但它仍然没有显示任何无线网络。我对 Ubuntu 很陌生，所以任何帮助都会很感激，谢谢。
答案1
首先发布输出
rfkill list
确保没有软块或硬块。硬块通常是开关，软块是驱动器。然后
lsmod | sort
查看是否列出了 rt2800pci 驱动程序（我认为这是适用于您的硬件的驱动程序）。它应该在默认安装中，无需特殊操作即可获得。如果没有加载，请检查 /etc/modprobe.d 中的任何文件中是否有类似以下内容的行：
blacklist rt2800pci
并将其删除或注释掉。
使用以下方法找到丢失的固件：
dmesg | grep -i firmware
如果与无线硬件有关，请安装/重新安装 linux-firmware 包（如有必要）。最坏的情况是从供应商处下载固件。一旦固件存在并加载，如果 /etc/modprobe.d 中的任何文件中不再有任何黑名单行，驱动程序应该会自动加载。
