无法在Ubuntu14.0.4笔记本电脑上连接互联网，使用中兴通讯(信任度cdma) AC2739 USB调制解调器
提问于 2015-05-20 17:56:58
许多Linux/Ubuntu用户都面临着这个问题-->(使用调制解调器zte/等等连接到互联网上……)由于现代软盘具有USB存储器+ modem+CD ROM，usb_modes开关.
我的问题是什么？->我不能**(有时能够)*使用中兴通讯( AC2739 )连接互联网。
Ubuntu是如何检测我的USB接口的？答复:有三种方式：
1)不检测USB设备，但lsusb显示设备。
2)检测设备(插入USB后的10种情况中有1种)，但网络管理器没有将其检测为宽带连接。
( 3)检测设备(在插入USB后的15种情况下)以及网络管理器将其检测为宽带连接
所有3种情况的系统日志：
普通日志(这就是每次插入USB dongle时系统日志显示的内容)。

在仔细分析系统日志之后，这个解决方案对我有效。
造成问题的原因:现代木棍的多种模式。
解决方案：
1.
gedit /etc/usb_modeswitch.conf
2.将此代码添加到顶部的可移植usb交换机中。
DisableSwitching=1
3.省省吧。
4.再次插入usb
5.用鼠标右键弹出usb光盘。
或者使用。
sudo eject /dev/sr1
6.等待5-10秒(检测它为调制解调器的时间)7.现在转到网络管理器
8.通过建立新的连接，信实网络将列在网络管理器与其连接中。
7.现在转到网络管理器。
8.通过建立新的连接，信实网络将列在网络管理器与其连接中。
就这样
信实还提供用户界面软件
只需使用
sudo ./文件名
使用
数独
这是对我有用的。
