Ubuntu Server 22.04.2 WiFi设置无法显示任何网络的排查求助

Ubuntu Server 22.04.2 WiFi设置无法显示任何网络的排查求助

我刚全新安装了Ubuntu Server 22.04.2,WiFi网卡明明已经被系统识别了,但在Gnome的设置界面里打开网络列表时,却看不到任何可用的WiFi网络。

无可用WiFi网络的设置界面截图

我查了各种解决方案,但好像都不符合我的情况,有没有大佬能帮我排查下问题?

已执行的排查步骤

1. 查看网络设备状态

执行命令 nmcli device,输出如下:

DEVICE TYPE STATE CONNECTION
wlp4s0 wifi disconnected --
enp5s0 ethernet unmanaged --
lo loopback unmanaged --

2. 检查无线设备软/硬阻断状态

执行命令 rfkill list,输出如下:

0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
2: hci1: Bluetooth
Soft blocked: no
Hard blocked: no

3. 查看网络硬件详细信息

执行命令 sudo lshw -C network,输出如下:
