我想在我的 T480 上使用移动宽带。首先我订购了L850-GL，但它不起作用，因为它使用PCI接口。正如您在这个论坛中看到的那样。同一线程中的人声称他们的设备上有一个可以工作的 L830-EB这个（德语）论坛有人成功地在 Kubuntu 上使用了相同的模块。
我可以在 Windows 10 虚拟机中成功使用该模块。加上我无法找到适合我的系统的“联想激活应用程序”这一事实，我可以假设激活成功或不需要。
我尝试跟随本指南但结果是：
$ sudo ./qmi_setup.sh start
error: couldn't open the QmiDevice: Operation timed out: device is closed
your wwan device may be RFKilled?
的删失输出为mmcli：
$ mmcli -m 0

当桌面环境启动时，系统会要求我提供 SIM 卡引脚。当我想在 NetworkManager 中选择网络时，唯一的选项是“添加新连接”。当我选择此选项时，NetworkManager 窗口将关闭。
我现在不知道还要检查什么。你能给我一些指点吗？
更新：
检查ModemManager的状态发现该设备不受支持。我想知道其他人是如何设法连接的......

答案1
引用自提到的论坛:
Die Lösung war，dass ich vergaß，dass ich im Network-Manager manuell das Profil anlegen muss。 Da ja nicht, wie beim WLAN, abgescannt wrd.战争是einfacher...tollpatschiger，unüberlegter aber mein Fehler。这是功能喷射。
翻译：
解决方案是在网络管理器中手动创建配置文件。因为与 WLAN 不同，它不会被扫描。这是一个简单的……愚蠢的、轻率的错误，但却是我的错误。现在可以了。
我只能同意。但我仍然认为当通过错误的对话框添加连接时 NetworkManager 不应该“崩溃”。
