移动宽带一旦连接就断开连接- Crunchbang

Question

几个月来，我的移动宽带(GSM)棒一直在与Crunchbang合作。昨天就停了。当我插入它时，它会出现在网络管理器中，我可以连接到它，但是一旦它被连接，它就断开连接。

大约在1.5周前，我改用了液态内核，直到现在，它也起了作用。切换回原来的内核并不能修复它。

电脑:联想U410

GSM棒:塞拉无线USB 308

以前有没有人遇到过这样的问题，知道如何解决？

编辑:尝试设置usb_modeswitch：

sudo usb_modeswitch -v 119 -p 68a3 -S

这方面的产出：

Looking for default devices ...
    No devices in default mode found. Nothing to do. Bye.

编辑:修正了usb_modeswitch命令中的错误

sudo usb_modeswitch -v 1199 -p 68a3 -S

该命令当时运行正常，但没有效果。

在多台计算机和多台操作系统上测试了这款设备后，宽带棒似乎存在硬件问题。
