网络管理员错过了我的网卡

我有以下网卡：

Bus 001 Device 002: ID 12d1:1506 Huawei Technologies Co., Ltd. Modem/Networkcard

它可以通过ip工具访问并正确使用dhcpcd（下面输出中的第三个条目）：

$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp5s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether bc:5f:f4:3a:84:84 brd ff:ff:ff:ff:ff:ff
3: wwp0s18f2u1i1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 1000
    link/ether 0c:5b:8f:27:9a:64 brd ff:ff:ff:ff:ff:ff
    inet 192.168.8.100/24 brd 192.168.8.255 scope global wwp0s18f2u1i1
       valid_lft forever preferred_lft forever
    inet6 fe80::48d6:a9ee:6db4:1236/64 scope link
       valid_lft forever preferred_lft forever

但NetworkManager似乎忽略了它：

$ nmcli device show
GENERAL.DEVICE:                         enp5s0
GENERAL.TYPE:                           ethernet

GENERAL.CONNECTION:                     --
GENERAL.CON-PATH:                       --

GENERAL.MTU:                            65536
GENERAL.STATE:                          10 (unmanaged)
GENERAL.CONNECTION:                     --
GENERAL.CON-PATH:                       --
IP4.ADDRESS[1]:                         127.0.0.1/8
IP4.GATEWAY:                            --
IP6.ADDRESS[1]:                         ::1/128
IP6.GATEWAY:                            --

我可以继续使用此连接，但有时dhcpcd我需要连接，并且不允许我建立连接，除非确保我有连接。VPNNetworkManagerVPNLAN

将 /etc/NetworkManager/NetworkManager.conf 更改 [ifupdown] managed=false为[ifupdown] managed=true
