我正在尝试在仅 CLI 服务器上建立 Wi-Fi 连接。我的以太网可以正常工作。我按照本指南操作，但无法连接。 https://docs.ubuntu.com/core/en/stacks/network/network-manager/docs/configure-wifi-connections
适配器已打开，我可以看到可用的 SSID
tom@hass:~$ nmcli d wifi list
IN-USE SSID MODE CHAN RATE SIGNAL BARS SECURITY
mynetwork Infra 6 130 Mbit/s 89 ▂▄▆█ WPA2
-- Infra 6 65 Mbit/s 89 ▂▄▆█ --
othernetwork1 Infra 1 195 Mbit/s 52 ▂▄__ WPA2
mynetwork Infra 11 130 Mbit/s 52 ▂▄__ WPA2
mynetwork Infra 1 130 Mbit/s 45 ▂▄__ WPA1 WPA2
othernetwork2 Infra 3 52 Mbit/s 45 ▂▄__ WPA2
othernetwork3 Infra 6 540 Mbit/s 42 ▂▄__ WPA2
但是当我尝试连接时，出现了以下信息：
tom@hass:~$ sudo nmcli d wifi connect mynetwork password mypassword
Error: Connection activation failed: (53) The Wi-Fi network could not be found.

我无数次确认了拼写和密码。
我刚刚设置了临时 wifi 网络并进行了测试。我遇到了同样的错误

Error: Connection activation failed: (53) The Wi-Fi network could not be found.
