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

enx00a0c6000000: flags=4163  mtu 1500
        inet6 fe80::afbb:cca8:4511:d902  prefixlen 64  scopeid 0x20

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

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

可以帮萌新指条路吗？

买个
最简单

我竟然不知道如何反驳你的观点，谢谢你的回贴

好简...我都看不懂,话说要给网卡配地址什么的吗?没玩过这东西

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.......

已经能识别为网卡了，我现在怀疑是不是拨号配置的问题

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
