无线设备英特尔公司设备 9df0（修订版 30）已于 18.04.3 禁用

我是 Ubuntu 新手。我会尝试在这个问题上提供尽可能多的细节，但如果我遗漏了任何内容，请在评论中告诉我，我会提供。如果这个问题在其他论坛上更合适，请告诉我哪个论坛。

我的无线接口一直正常工作，直到 3 天前，我记得一个更新，我同意禁用它。当我这样做时sudo lshw -C network，我得到：

*-network DISABLED        
       description: Wireless interface
       product: Intel Corporation
       vendor: Intel Corporation
       physical id: 14.3
       bus info: pci@0000:00:14.3
       logical name: wlo1
       version: 30
       serial: 00:bb:60:08:95:85
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress msix bus_master cap_list ethernet physical wireless
       configuration: broadcast=yes driver=iwlwifi driverversion=5.1.0-050100-generic firmware=46.6bf1df06.0 latency=0 link=no multicast=yes wireless=IEEE 802.11
       resources: irq:16 memory:b431c000-b431ffff

当我这样做时iwlist scan，我得到：

wlo1      Failed to read scan data : Network is down
lo        Interface doesn't support scanning

当我执行此操作sudo service network-manager restart然后sudo service network-manager status，我在输出中收到此错误（此处缩写）：

<error> [1576682510.9833] sup-iface[0x5655383f5240,wlo1]: error adding interface: wpa_supplicant couldn't grab this interface.

最后，当我这样做时rfkill list all，我得到：

0: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: asus-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
2: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
3: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

这些就是我所关注的主要内容。

我重启了电脑几次，重启了网络管理器，并尝试执行ip set wlo1 up（ifconfig set wlo1 up后一个命令对我来说已经过时了，所以不起作用）。

现在介绍一下我的系统信息：我有一台华硕 Zenbook，并且正在双启动 Ubuntu 18.04.3 LTS。同时，我正在使用手机作为以太网连接。当我运行 时lsusb，我得到：

如果我遗漏了任何有用的信息，请告诉我。

首先十分感谢。

答案1

您正在使用不受支持的主线内核。

我建议安装 5.3 HWE Ubuntu 内核。

在终端中运行：

sudo apt install linux-generic-hwe-18.04-edge

然后重新启动。
