我正在尝试在ubuntu核心16.04上配置带有蜂窝接口的新设备。我运行了NMCLI包。在我添加连接之前，我检查了接口
# nmcli dev
DEVICE TYPE STATE CONNECTION
eth1 ethernet connected Wired connection 1
wlan0 wifi disconnected --
eth0 ethernet unavailable --
cdc-wdm0 gsm unavailable --
lo loopback unmanaged --
我添加了我的连接：
nmcli con add type gsm ifname cdc-wdm0 con-name MyConnection apn myapn.com
最后，我尝试通过运行来启动连接：
nmclil con up MyConnection
Error: Connection activation failed: No suitable device found for this connection
我也粘贴了Config的输出：
# nmcli -p con show MyConnection

我的问题是如何启用不可用的设备以及为什么它不可用？我可以检查什么来帮助我解决问题。
任何帮助都会很棒，因为我只是在Snappy上开始。
答案 0 :(得分：0)
好的，所以我设法解决了自己的问题，我采取的步骤如下：
1）检查我的网关上的调制解调器是否被ubuntu核心读取：
$ sudo mmcli -L
Found 1 modems:
/org/freedesktop/ModemManager1/Modem/0 [Generic] MBIM [1519:0020]
2）检查SIM是否正确读取：
$ sudo mmcli -m 0
/org/freedesktop/ModemManager1/Modem/0 (device id 'd8b328efa783ca35a022d6b44b878981e67a5903')

这是我意识到我的SIM卡未在网关中找到并且我的SIM卡已损坏，我已经更换了我的SIM卡并想出了上面的输出。
3）配置新APN或编辑现有APN。 （我发现重新添加连接更容易）
确保您使用root（sudo su -）
a）删除失败的现有连接
#nmcli con delete MyConnection
b）创建新连接
#nmcli con add type gsm ifname cdc-wdm0 con-name MyWorkingConnection apn MyNewApn.com
4）将用户名和密码添加到新连接
#nmcli con edit MyWorkingConnection
此时你将进入nmcli＆gt;提示。输入 help 以获取可帮助您编辑连接的命令列表。对我来说，我需要添加用户名和密码，所以我通过输入以下内容来实现：
nmcli> set gsm.username data
nmcli> set gsm.password <passwordgoeshere>
nmcli> save
nmcli> quit
此时我的连接已建立。我找到了命令
#nmcli m
在另一个会话中打开，有助于检查接口更改的状态。
希望这可以帮助一些人！
