网卡型号
ZTE MF832S
系统版本
Ubuntu 17.10 \n \l
通过 lsusb 能够查看到该设备已被识别为网卡
Bus 001 Device 006: ID 19d2:0199 ZTE WCDMA Technologies MSM
通过 ifconfig 命令也能佐证这一点

遇到的问题则是通过 wvdialconf 生成配置文件时，出现了一个 CME ERROR 6003，没能找到对应的错误解释
art1st@thinkpad:~$ sudo wvdialconf

Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?

有些无线网卡是有 SD 卡模式的，确定一下你的是不是属于这种
买这种网卡最好先上网查一下哪种型号最方便 要是熟悉 AT 指令还爱折腾的话，可以安装 mincom 调试....... |

没用过 4G 网卡，用过 GPRS 网卡
那种 GPRS 蜂窝网卡是串口连接的，USB 应该就是一个 USB 转串口，然后 /dev/ttyUSB0，然后通过 AT 指令建立连接 |

可以参考下树莓派上的 3g 拨号，用的是 pppd，选个具有中断功能 /dev/ttyUSB 节点，一般是 ttyUSB2 或 3

可以试一下此文的方法，我也是 MF832s，把波特率改成 9600 就可以正常拨号。系统 Ubuntu 16.04
