我昨天（2015 年 12 月 22 日）安装了 Ubuntu 15.10。
我安装了 wvdial 并对 /etc/wvdial.conf 文件做了一些更改。将我的 usb cdma 1x 调制解调器与 UTL Nepal 的 usim 连接。然后我输入 sudo wvdial 并按下回车键。连接已建立，因为它显示了 ip 地址和 dns。但我仍然无法使用互联网。
我关闭了计算机，然后启动计算机并连接调制解调器。但是这次当我输入 sudo wvdial 时，我收到以下消息：
--> WvDial: Internet dialer version 1.61
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATE0
--> Sending: ATQ0
--> Re-Sending: ATE0
--> Modem not responding.
我在 Google 上搜索解决方案，点击了几个链接，但无法解决这个问题。请帮帮我。
/etc/wvdial.conf的内容为：
[Dialer Defaults]
Modem = /dev/ttyUSB0
Baud = 230400
Init1 = ATE0
#Init2 = AT$PBTYPE=1 RPTCON=1 MTRPTTYPE=3 SMSRUIM=0 SMSTYPE=1
Init3 = AT+CTA=0
Init4 = ATEOV1
Init5 = AT
Init6 = ATS0=0
ISDN = 0
Modem Type = Analog Modem
Phone = #777
Username = [email protected]
Password = 9723368036
Stupid Mode = 1
New PPPD = yes
我在下面提到了调制解调器的详细信息：
运行后：lsusb

“067b:2303 Prolific Technology, Inc. PL2303 串行端口”适用于我的 cdma 调制解调器
在我输入以下命令后：
sudo modprobe cdc_acm
dmesg | tail
我收到以下消息：

所以请帮助我.....
我尝试使用 pppd ，我输入 sudo pppconfig 并按回车键。
我按照屏幕上的说明设置了一个名为 providerUTL 的配置。
然后我输入了 pon providerUTL，但没有显示任何消息。
我输入了 plog 并收到消息：
