【原创】UBUNTU9.10下配置LC5730 3G上网教程

htsky

ubuntu 9.10已经把usbserial编译进了内核，再也不能在程序里面动态modprobe usbserial的方法加载usb设备。
因此我们这样来配置LC5730

1、下载附件lc5730.conf.rar解压后以root权限放入/etc/modprobe.d/
再以root权限，在/etc/modules 里加入行usbserial

重启电脑就OK。

加入etc/wvdial.conf如下代码

[Dialer Defaults]
Init1 = ATZ
Init3 = AT+CFUN=1
Init5 = AT+cgdcont=1,"ip","CMNET"
Modem Type = USB Modem
Baud = 460800
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
Phone = *99***1#
Password = any
Username = any
Stupid Mode = 1

使用WVDIAL拨号
hantao@TAGEN:~$ wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
OK
--> Sending: AT+CFUN=1
OK
--> Sending: AT+cgdcont=1,"ip","CMNET"
OK
--> Modem initialized.
--> Sending: ATDT*99***1#
--> Waiting for carrier.
CONNECT 2936012
--> Carrier detected.  Starting PPP immediately.
--> Unable to run /usr/sbin/pppd.
--> Check permissions, or specify a "PPPD Path" option in wvdial.conf.
出现错误，需要修复权限
hantao@TAGEN:~$ ls -al /usr/sbin/pppd
-rwsr-sr-- 1 root dip 277352 2009-02-21 01:25 /usr/sbin/pppd
hantao@TAGEN:~$ sudo chmod +x /usr/sbin/pppd
hantao@TAGEN:~$ ls -al /usr/sbin/pppd
-rwsr-sr-x 1 root dip 277352 2009-02-21 01:25 /usr/sbin/pppd 注意一定要是-rwsr-sr-x才可以正常使用
修复完成，继续测试
