如何与 Sierra Wireless MC7354 的 WWAN 建立 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 可以看到和控制调制解调器。
$ mmcli --modem 0
返回大量重要信息。（这就是我知道调制解调器是 MC7354 的方式。）

端口列表显示了几个端口：

$ mmcli --modem 0 --simple-connect="apn=internet"
成功了
$ mmcli --bearer 0

如何在 Ubuntu 上建立连接以使用此接口？
$ ifconfig -a

如何与此设备建立 IP 连接？
谢谢您的帮助！
我想你仍然想知道。

你已经这样做了：
\n\n$ mmcli --bearer 0\n\nBearer \'/org/freedesktop/ModemManager1/Bearer/0\'\n -------------------------\n Status | connected: \'yes\'\n因此基本上剩下的就是使用给定的 IP 和网络掩码设置来设置适当的 WWAN 接口。但是，您还必须将想要通过接口的流量路由到定义的网关。
\n\n您也许应该阅读服务器指南中第 43 页的整个部分\n请注意，如果您使用 netplan，它会搞砸您，例如，它将忽略您为网络管理器手动添加的连接。
\n\n IPv4 configuration \n | method: \'static\'\n | address: \'100.232.81.142\'\n | prefix: \'30\'\n | gateway: \'100.232.81.141\'\n | DNS: \'10.177.0.34\', \'10.177.0.210\'\n | MTU: \'1430\'\n它所说的静态是无关紧要的，仅意味着只要承载保持连接，您就会拥有该 IP。除非您购买静态 IP，否则当您重新连接承载时，ISP 很可能会为您提供一个新 IP。
\n\n您收到的设置很可能基于您连接的 APN。
\n\n依赖于 ISP，他们也可以强制使用他们的 DNS。
\n\n所以，我的问题是，当您至少有一个易于使用的网络管理器可以处理这一问题时，为什么还要费心手动执行此操作呢？

It manages ethernet, WiFi, mobile broadband (WWAN), and PPPoE\n devices, and provides VPN integration with a variety of different VPN\n services.\n .\n This package provides the userspace daemons and a command line interface to\n interact with NetworkManager.\n .\n Optional dependencies:\n * avahi-autoipd: Used for IPv4LL, a protocol for automatic Link-Local IP\n address configuration.\n * ppp: Required for establishing dial-up connections (e.g. via GSM).\n * dnsmasq-base/iptables: Required for creating Ad-hoc connections and\n connection sharing.\n * libteam-utils: Network Team driver allows multiple network interfaces to be\n teamed together and act like a single one. This process is called "ethernet\n bonding", "channel teaming" or "link aggregation".\n如果您阅读了上面的内容，它就不是任何需要桌面的地方，实际上它恰恰相反，桌面会将其完全拉入以执行网络部分。
\n\n所以我的建议仍然是一样的，安装网络管理器。
\n\n如果您已经使用任何其他网络管理器（例如networkd），只需将网络管理器配置为仅配置wwan。
\n\n这可以通过编辑来完成/etc/NetworkManager/conf.d/10-globally-managed-devices.conf
unmanaged-devices=*,except:type:wwan,except:type:gsm\n要设置连接，您可以使用nmcli或手动创建配置：
sudo vim /etc/NetworkManager/system-connections/myisp
[connection]\nid=myisp\nuuid=755d5082-e2e3-4691-873a-0669b27aaaa2\ntype=gsm\ninterface-name=cdc-wdm0\npermissions=\ntimestamp=1547308598\n\n[gsm]\napn=internet.public\nnumber=*99#\n\n[ipv4]\ndns=8.8.8.8;8.8.4.4;1.1.1.1;\ndns-search=\nignore-auto-dns=true\nmethod=auto\n\n[ipv6]\naddr-gen-mode=stable-privacy\ndns-search=\nmethod=auto\n希望这会引导您走向正确的方向，祝您好运:)
