NetworkManager 添加连接但不设置接口

  • 772

我运行以下命令来添加到网络管理器的新连接：

nmcli con add con-name MIDVERCORP ifname wlan0 type wifi ssid "MIDVERCORP"

当我查看我配置的连接时，这个新连接已添加，但接口/设备未设置为wlan0.

# nmcli con
NAME                UUID                                  TYPE      DEVICE

# ip link show wlan0

    link/ether c0:ee:40:50:25:c0 brd ff:ff:ff:ff:ff:ff

为此连接设置 wlan0 接口我缺少什么？

    我的问题是 wpa_supplicant 没有运行。

    systemctl start wpa_supplicant

    然后我可以运行nmcli dev wifi rescan; nmcli dev wifi list并查看可用的 AP。
