除了内置的 wifi 设备之外,我还安装了 tp-link usb 设备,运行后我可以在 ifconfig 上看到它sudo ifconfig ra0 up
:
ra0 Link encap:Ethernet HWaddr 50:3e:aa:ac:18:3f
inet6 addr: fe80::523e:aaff:feac:183f/64 Scope:Link

但是它没有在 nmcli 上列出:
$ nmcli d
DEVICE TYPE STATE
E0:AA:96:7E:E2:AD bluetooth disconnected

58:3F:54:3F:0A:54 bluetooth disconnected
wlan0 802-11-wireless connected
eth0 802-3-ethernet unavailable
我缺少什么?
