系统:Asus Vivobook 15 (X415 / M415) 上的 Ubuntu 20.04 [无其他操作系统]
问题:NetworkManager 未找到任何 Wi-Fi 设备:
root@bhagirathi:~# nmcli device wifi list
root@bhagirathi:~# nmcli device wifi rescan
Error: No Wi-Fi device found.
尽管驱动程序已正确加载(见lspci
下文)且设备未被阻止(见rfkill
下文)。ifconfig
并且iwconfig
未显示任何无线适配器。该设备已被内核识别(见lshw -C network
下文)。
[编辑:解决了。只需按住电源按钮关闭笔记本电脑即可解决问题。参见原答案]
