未检测到无线驱动程序

当输入 iwconfig 时，我只得到“无无线扩展”

如何让 Ubuntu 无线驱动程序被检测到？

sudo rfkill list：

答案1

输出sudo rfkill list显示你的网卡被“软阻塞”了。

当无线网卡被发出关闭信号时可能会发生这种情况 - 这可能是由于 Fn+ 类型的开关造成的。

如果您无法识别键盘开关，请执行以下步骤：

  1. 在终端中运行：

    sudo rfkill unblock hp-wifi; sudo rfkill unblock wifi; sudo rfkill unblock all

  2. 重新运行sudo rfkill list以确认卡已解锁。

  3. 重启

  4. 再次重新运行sudo rfkill list以确认已保留解除阻塞。

  5. 重新运行sudo lshw -class network-您现在应该看到内核已经识别（或未识别）无线网卡。

如果无线内核模块已经被识别（它不应该显示“无人认领”），网络管理器现在应该能够看到您所在地区可用的无线网络。
