我有一台新的 Dell Latitude e7440 和一张 Dell Wireless 5570 HSPA+ 移动宽带卡。我无法让宽带卡工作。
我可以看到卡片：

但是我不能使用以任何方式该卡。
- 没有
/dev/ttyUSBx可以输入 AT 命令的地方。 - 我在网络管理器中看不到移动宽带连接。
mbim-network诸如简单地说调制解调器的连接失败之类的工具
我的戴尔 BIOS 版本是A10，从 BIOS 中我可以看到该卡。它已启用，从这个角度来看，它应该没有任何问题。如果我需要调试驱动程序，我愿意尝试一下，但我需要一些关于从哪里开始的指示。任何帮助深表感谢。
下面是调试输出的列表。如果您认为有任何帮助，请在评论中询问更多信息。

答案1
戴尔品牌的 Sierra Wireless 调制解调器，例如 5570（我自己现在买了一个）需要一个神奇的“DMS Set FCC Auth”命令才能从低功耗模式中恢复，这里有更好的解释：https://sigquit.wordpress.com/2015/02/09/dell-branded-sierra-wireless-3g4g-modem-not-online/
如果您使用的是 ModemManager，您可以尝试libqmi从 git 编译您的 ModemManager 并解决此问题。
答案2
您的选项中缺少 APN --wds-start-network。如果您在 CDMA/EVDO 网络中，则不需要它，但在 GSM/UMTS/LTE 中（通常）需要明确的一个。
dhclient一旦 QMI WDS Start Network 返回且没有错误，只需尝试在 WWAN 界面中运行即可。
