笔记本电脑：HP Spectre X360 15-bl001na
Ubuntu 22.04 没有看到任何 wifi 网络，然后我用下面的命令检查，看到“DISABLED”。
我怎样才能启用该接口？
$ sudo lshw -class network
*-network DISABLED

和 的结果sudo ifconfig eth0 up如下ifconfig -a：
$ sudo ifconfig eth0 up
eth0: ERROR while getting interface flags: No such device
$ ifconfig -a
enx00e04c689b6e: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

结果为frkill：
$ rfkill list all

Soft blocked: no
Hard blocked: no
2: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no
这是的内容/etc/network/interfaces：
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
我还可以补充一点，在 Ubuntu 配置面板中，WiFi 当然是启用的，但“可见网络”却一直在旋转 截屏
还添加有关 iwlwifi 模块的信息：

同样的问题。我发现我移动了一些硬件，特别是 LSI 磁盘控制器。这个看似无关的良性行为导致我的网卡地址发生变化！
要解决此问题，只需编辑自动生成的 netplan 文件
sudo /etc/netplan/00-installer-config.yaml
cat /etc/netplan/00-installer-config.yaml
# This is the network config written by 'subiquity'
network:
ethernets:
enp6s0:
dhcp4: true
version: 2
ifconfig包括、等在内的许多工具ip a都会向您显示正确的接口 ID。在我的示例中，接口 ID 已从 enp5s0 更改为 enp6s0。
希望这可以帮助！
