如何建立与 Sierra Wireless MC7354 的 WWAN 的 IP 连接？
我有一个带有运行 Ubuntu 18.04的Sierra Wireless MC7354 调制解调器的系统。
ModemManager 可以查看和控制调制解调器。
$ mmcli --modem 0
返回大量重要信息。（这就是我知道调制解调器是 MC7354 的原因。）
/org/freedesktop/ModemManager1/Modem/0 (device id '232972a04adf83122a392fd83b274431de596ebd')
-------------------------
Hardware | manufacturer: 'Sierra Wireless, Incorporated'
| model: 'MC7354'
|
端口列表显示了几个端口：
ports: 'ttyUSB0 (qcdm), wwp0s20u5i8 (net), wwp0s20u5i10 (net), cdc-wdm0 (qmi), cdc-wdm1 (qmi), ttyUSB2 (at)'
$ mmcli --modem 0 --simple-connect="apn=internet"
是成功的
$ mmcli --bearer 0
Bearer '/org/freedesktop/ModemManager1/Bearer/0'
-------------------------

显示调制解调器已连接到互联网 (?)。
如何在 Ubuntu 上建立连接以使用此界面？
$ ifconfig -a
