vi /etc/usb_modeswitch.conf
将里面内容改为：
DisableSwitching=0
DefaultVendor= 0x19d2
DefaultProduct= 0x0026
TargetVendor= 0x19d2
TargetProduct= 0x0152
MessageContent="5553424312345678240000008000061b000000020000000000000000000000"
CheckSuccess=5
HuaweiMode=0
运行usb_modeswitch -W -c /etc/usb_modeswitch.conf
vi /etc/wvdial.conf
内容为：
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
New PPPD = yesPhone = #777
Modem = /dev/ttyUSB0
Username = ctnet@mycdma.cn
Password= vnet.mobi
wvdial 3g拨号正常上网。
时间久了不定时掉线
掉线提示：A modem hung up the phone (exit code 16)
dmesg 显示多出如下信息：
option1 ttyUSB0: option_instat_callback: error -108
option1 ttyUSB0: GSM modem (1-port) converter now disconnected from ttyUSB0
option 1-1.3.2:1.0: device disconnected

在掉线以后再用wvdial 3g拨号则会出现如下情况：
--> WvDial: Internet dialer version 1.61
--> Initializing modem.
--> Sending: ATZ
--> Sending: ATQ0
--> Re-Sending: ATZ
--> Modem not responding.
无法拨号
拔掉3g上网卡再重新插上，重新拨号又可以正常上网，求教一下3g上网卡掉线提示是什么意思，该如何解决。
本人刚入论坛不久没法给出多余金币望见谅。
